    + *
  • Type resolution is folded into emission (each expression returns its + * code and static type); the standalone resolver pipeline arrives with + * M2 when inference needs grow.
    • + *
  • Stub-class constructors with named arguments emit as + * allocate-then-setter sequences (ANF); program-class constructors use + * canonical positional order with defaults inlined at call sites.
    • + *

transpiler/runtime bring-up Transpiler (dart-transpiler): the full 159-file Flutter Gallery now transpiles to 0 errors and the 563 emitted Java files compile clean, then boot and run in the JavaSE simulator. Key correctness fixes, all general (not gallery-specific): - Static-init ordering: emit static fields in dependency order (direct refs + same-class static-method-call transitive deps) so Java's top-to-bottom static init matches Dart's lazy/order-independent semantics. - Null-shorting: a Dart `a?.b.c()` now guards the whole trailing selector chain via a propagated short-guard on Out, materialized at value consumption. - Import-scoped class resolution: a simple name shared across files resolves via the referencing library's imports (Program.resolveClass + emitCtorCall), not a flat last-registered map. - Captured for-loop var gets a per-iteration effectively-final alias. - Nested-switch trailing-break no longer double-emits an unreachable break. Runtime (flutter-runtime, dart-runtime): MaterialApp resolves onGenerateRoute for the initial route (routing-based apps with no home:); Localizations pipeline wired (delegate.load -> LocalizationsScope InheritedValueProvider -> Localizations.of); Future.getNow() for synchronous results; plus the widget/type surface added across the transpiler passes to reach 0 compile errors.

The home's whole subtree is produced by such a builder, so it previously never built. (High-leverage: used across the app.) - AdaptiveBreakpoints.getWindowType returns the real bucket from the window's LOGICAL width (device px / Dp.scale) instead of a hardcoded `medium`, so a phone-sized window gets the mobile layout (isDisplayDesktop was always true). - StatefulElement.firstBuild now runs didChangeDependencies after initState and before the first build, matching Flutter; widgets that create controllers there (a PageController sized from MediaQuery) no longer read null. - Transpiler: recover a dropped inferred witness for BuildContext ancestor lookups (X.of(context) => context.dependOnInheritedWidgetOfExactType()) from the enclosing return type, so SplashPageAnimation.of etc. resolve.

We were always loading the unscaled file and upscaling it, so every bundled image was soft. FlutterAssets.open now probes candidates in Flutter's preference order (the smallest variant at least as dense as the screen, then denser, then the closest lower ones, then the unscaled asset) and reports which density it found. Flutter reads that set from a build-generated manifest; probing gets the same answer without one, and a missing variant just falls through. ImageRenderElement rescales the natural size by screen-density/asset-density, so an unsized image occupies the same logical box whichever variant backs it. Adds a CategoryHeaderShapeTest that pins the gallery category header's geometry layer by layer (Wrap, Row/Expanded, SizedBox, Material, Container), so a card that looks wrong on screen can be attributed to a node instead of eyeballed.

NavigatorState was a stub whose every method returned without doing anything, so the gallery's Navigator.of(context).restorablePushNamed('/demo/') -- how it reaches all ~130 demos and all 6 studies -- silently did nothing. - Navigator now resolves a route NAME the way Flutter does: the `routes` map, then onGenerateRoute, then onUnknownRoute. MaterialApp publishes its table on build (and gains the missing onUnknownRoute), and its own initial-route lookup goes through the same resolver rather than a private path. - NavigatorState's named/replacement/push/pop/popUntil surface is wired to that resolver instead of returning null. An unresolvable name is logged, not thrown -- a dead link in one corner of an app should not take it down. - Navigator.of(context) now returns a handle BOUND to the calling context, because a push has to know where it came from: A pushed route mounts as a fresh element-tree root (its own CN1 Form), so its ancestor chain ended immediately and every Foo.of(context) inside the page resolved to null -- the gallery's pages died on GalleryLocalizations.of and GalleryOptions.of. In Flutter a route builds below the app and inherits everything above it. Element now continues an exhausted lookup from a `contextFallback` -- the context that pushed the route -- which restores the inheritance WITHOUT joining the two trees structurally, so the render/host logic still sees a genuine root (a root Scaffold must keep owning its Form's Toolbar). Also publishes tap targets to the accessibility tree: a GestureDetector or InkWell with an onTap now exposes the button role and an activate action on its overlay -- the only component that knows the subtree is tappable. Without it a tappable Flutter subtree was invisible to screen readers and to anything driving the UI through semantics.

A horizontal boundary lays its content out with a tight viewport height and an unbounded width — the vertical contract mirrored — and hands CN1 an X-scrollable pane driven by the new HorizontalScrollRootLayout. - PageView lays its pages along that axis, each sized to the controller's viewportFraction of the viewport. That fraction is the whole point of the widget's look: a value below 1 is what makes the neighbouring pages peek in at the edges, so it has to reach the pages as a real constraint. It also paints no scroll indicator, matching Flutter, where the peeking pages ARE the affordance. - ListView(scrollDirection: Axis.horizontal) rides the same axis support. Its windowing stays vertical-only — the scroll math and spacers are written against item heights — so horizontal lists build eagerly, which is what a row of cards wants anyway.

The gallery's settings gear, the Rally charts and every other hand-drawn widget were therefore blank boxes. GraphicsCanvas implements the dart:ui Canvas against CN1's Graphics: - Transforms are kept HERE as a 2x3 affine matrix and every coordinate is mapped through it before reaching Graphics, rather than leaning on CN1's optional Transform support — a painter must not silently draw untransformed geometry because a port lacks a capability. - Painters work in LOGICAL pixels, so the canvas starts pre-scaled by the device pixel ratio and the painter is handed a logical-pixel size. A painter written against Flutter's coordinate system lands at the right physical size on any density. - Rects, rounded rects, ovals, arcs, lines and full paths become GeneralPaths in device space; Paint's style/width/cap/join/alpha drive fill vs stroke. A misbehaving painter is logged, not allowed to take the frame down. Two real ParparVM API gaps surfaced while compiling the iOS build of this app, both CLDC-era omissions that would hit any app doing arithmetic: - java.lang.Math was missing acos/asin/atan2/exp/log/log10 — added with C natives and the matching JS-port bindings, so the methods exist on every backend rather than only where they were needed today. - java.lang.Long was missing the Java 8 static hashCode(long); the instance method now delegates to it. Also fixes a latent ordering bug the horizontal carousel exposed: a PageView page sizes itself against the VIEWPORT, but read it from size(), which is only assigned after layout returns — so pages measured against a stale (initially zero) extent and the carousel came up blank. The scroll boundary now reports its viewport before laying the content out.

The gallery matches every route name with a RegExp, so nothing rendered at all. RegExp now runs on Codename One's own engine (com.codename1.util.regex.RE) — plain Java that translates like any app class, so the behaviour is the same on every target instead of only where java.util.regex happens to exist. Its Perl5 syntax covers what Dart's ECMAScript grammar uses in practice (anchors, classes, quantifiers, alternation, groups); unicode/dotAll have no engine counterpart and are recorded but inert rather than silently changing a match. RegExpMatch now SNAPSHOTS its groups and offsets: the engine carries match state on the compiled pattern and overwrites it on the next match, so a Match reading through to it would change under the caller — a Dart Match is a value. Two more gaps found by compiling the iOS build: - java.util.Collections was missing emptyIterator(). - The translator renames devirtualized DartLongList element access to cn1InlDllGet/Set, but those intrinsics were never added to cn1_intrinsics.h — so every app hitting that path failed to compile for iOS. Added, bounds-checked against the logical length exactly as DartLongList is, falling back out-of-line so RangeError stays single-sourced. Also: a pushed route whose Scaffold is nested (the gallery's demo pages sit inside a ColoredBox) draws its own in-canvas AppBar, so the Form's Toolbar is now hidden for it instead of adding a second bar — its inset was shrinking the Flutter canvas and leaving those pages floating inside a margin.

The runtime now carries a diagnostic context that the element tree sets around each build, so the error reads "... (while building GalleryApp)" — Flutter reports the error-causing widget for the same reason. In the same spirit: - A failed inherited-widget lookup now names the type it wanted and lists the ancestors it actually walked, instead of returning null and letting the app die on `Foo.of(context)!` somewhere else. - MaterialApp no longer swallows a localizations delegate's failure; it says which delegate failed for which locale. Flutter Forms also had CN1 chrome padding on the Form and its content pane. Flutter owns the whole canvas and draws its own padding and safe areas, so that inset is a margin it never asked for — it was framing pushed pages. Fixes ParparVM's Class.isAssignableFrom, which passed its arguments to instanceofFunction(source, dest) backwards: A.isAssignableFrom(B) asks whether B is assignable to A, so the ARGUMENT is the source and the receiver the destination. It answered the reverse question.

Class.isInstance passed those the other way round, so it searched the TARGET's supertype table for the object's class and answered false whenever the object was a strict subclass. Verified in a generated build: classInstanceOfArr694 (GalleryLocalizationsEn) = {1428, 303, -1} classInstanceOfArr1428 (GalleryLocalizations) = {303, -1} so isInstance(GalleryLocalizations, aGalleryLocalizationsEn) looked for 694 in the second table and said no. Every Class.isInstance in a native build was wrong unless the two types were exactly equal — which is why the transpiled gallery's Localizations.of(context) resolved to null on iOS while working on the JVM. Both isInstance and isAssignableFrom now pass the receiver Class first, and a comment above them records the argument order so the misleading parameter names cannot mislead again. (An earlier commit in this branch "fixed" isAssignableFrom on the strength of those names; it was correct and is restored here.) Also adds the missing Class.getSuperclass(), and drops the speculative superclass-walk fallback from Element.isInstanceOf — it was papering over this bug, and it called getSuperclass before ParparVM had it, which broke the iOS build.

An uncaught error on the EDT raises Codename One's modal error dialog, which blocks the EDT — so the first broken screen stalled every screen after it, and "this screen is broken" became "the app is dead". FlutterErrorReport.install() collects instead: it consumes the error, records it with the widget that was building and the route that was on screen, counts repeats rather than reprinting them, and lets the app carry on. That context is what makes a report usable, because transpiled build methods are inlined into the framework's frame on some backends and the stack alone names nothing but Element.updateChild. The quieter mode is worse: a screen comes up blank and NOTHING throws, because the widgets it needs are stubs that pass their child through or draw nothing. A sweep of the gallery reported zero errors against six blank screens. Eighteen such widgets now declare their gap through the same channel, so a sweep answers "what did this screen need and not get" instead of shrugging: 18x OpenContainer: the container transform renders nothing [route /demo/motion] 6x Transform: scale, rotation and translation are ignored 5x Opacity: opacity is ignored; the child paints fully opaque Inherited-scope widgets that legitimately pass their child through (Theme, MediaQuery, IconTheme, FocusScope...) are deliberately not reported. Opt-in, not automatic: a shipping app wants the dialog or its own crash reporting, so runApp does not install this.

charset=UTF-8 Content-Transfer-Encoding: 8bit Both passed their child straight through, so every Transform.scale and Opacity in an app was computed and discarded. The gallery's carousel drove a scale animation at 60fps that could not possibly show. The render tree is flat — every element's component is a sibling in one host container, positioned absolutely — so an ancestor cannot wrap its descendants in a paint effect, because they are not its children. EffectRenderElement gives such a widget a nested container with its own RenderHost, the same device the scrollables already use, which makes the subtree genuinely nested and therefore paintable through. Layout is untouched: the child measures against the incoming constraints and the effect takes exactly its size, as in Flutter. - Opacity composites the whole pane through the Graphics alpha, so overlapping children fade as one layer rather than tinting individually, and nested Opacity multiplies. - Transform scales/rotates about the element's centre (Flutter's default alignment, and what the carousel expects), and translates by shifting the origin — which needs no matrix support and so works on every port. A port without transform support still gets the translation and reports the rest instead of dropping it silently. An explicit origin/alignment is not honoured yet and reports itself.

Both now build a RoundRectBorder from the radius (and a shadow scaled from the elevation), matching what CardRenderElement already did. CN1 draws one radius for all four corners, so a decoration with mixed corners takes its top-left — closer than dropping the rounding altogether.

The gallery's study card is a Material with elevation 4, a 10dp radius and Clip.antiAlias, and it still looked square: the cover image fills the surface and, in a flat render tree, paints as an unrelated sibling over the rounded background. So Material now nests its subtree through EffectRenderElement, which is the prerequisite for clipping it. The clip itself is NOT done. An attempt to cut the subtree with a rounded-rect path built from absolute coordinates cut away most of the content — the category labels vanished and the card image was sliced — because setClip(Shape) does not share the coordinate space the rest of the paint path uses. Reverted rather than shipped: a square corner is a blemish, a missing label is a broken screen. The gap now reports itself instead of being a silent visual difference. Style derivation is also cached against a signature, so a RoundRectBorder is not rebuilt on every frame of every surface.

Its guard asked only whether the value was a subtype at all, so it also fired on the ordinary case where the subtype already inherits exactly the instantiation being assigned to. Every StatefulWidget paid for it: createState() returned (State) (Object) (new _MyHomePageState()) where plain new _MyHomePageState() is what Java wants, across all 537 generated files. Resolve what instantiation the value inherits and skip the cast when it already matches, walking the same superclass chain isSubtypeName walks and substituting each class's type parameters on the way down. The goldens caught this, and reseeding them also picks up the library-privacy change they had been left behind by: a Dart `_name` member is private to the LIBRARY, not the class, so sibling classes reach it and its accessors are emitted package-private rather than skipped.

Align ignored widthFactor/heightFactor. It stored both and read neither, so it always filled the bounded axes. That is the geometry an expand/collapse runs on: the gallery's category and settings lists animate ClipRect(child: Align(heightFactor: t, child: ...)) with t from 0 to 1, and with the factor dropped every frame of that animation laid out identically. Now the box takes the Flutter fraction of the child while the child keeps its full size. ClipRect did not clip - it passed its child straight through, so there was nothing to hide the part of the child that does not fit yet. It gets the nested pane EffectRenderElement already provides for Transform and Opacity: the render tree is flat, every element absolutely positioned as a sibling in one host, so a widget can only affect its descendants' paint by nesting them. The clip itself is free once nested - Component.internalPaintImpl already confines a component's paint to its bounds. CustomPaint anchored its canvas at getAbsoluteX()/getAbsoluteY(). A Graphics being painted through has already accumulated its ancestors' translation (Container.paintChildren translates on the way down), which is why the whole of Codename One draws with getX(). The absolute origin added that offset a second time and pushed the drawing outside the bounds the component clips to - the painter ran every frame and produced nothing. The gallery's settings icon was the blank white notch in the top right. arcTo dropped its forceMoveTo flag and always started a new subpath. Flutter joins the arc to the current point with a line when forceMoveTo is false, which is how two opposing half-circle arcs become one stadium; ours produced two disconnected discs, so each stick of the settings icon painted as a pair of dots. A Paint carrying a shader has no colour of its own and the canvas only ever read paint.color(), so anything drawn with a gradient came out black - including both sticks of that icon, whose whole identity is being pink and teal. Fill the shape with the gradient by clipping to it and running Codename One's linear gradient over its bounding box; a port without shape clipping fills solid with the ramp's midpoint, since the shape matters more than the ramp. Verified in the simulator against the native Flutter capture: the settings icon now draws a pink stick and a teal stick with their knobs where it drew a blank notch, and tapping a category reveals its demo rows. The animation's intermediate frames are not verified - a screenshot round-trip through the simulator's MCP server costs ~0.6s against a ~200ms animation, so the geometry is pinned by AlignFactorTest instead.

That is 37x the 16fps budget, and it is what "unresponsive" actually was - input dispatch itself was already free (0ms per drag event), and an idle app runs no frames at all. The cause: every box cached ONE (constraints -> size) result, and Codename One asks a container two different questions. getPreferredSize measures with loose unbounded constraints; layoutContainer lays out with tight ones. The two alternate, so each evicted the other on every box in the tree and a single changed leaf re-measured everything: 7635 layout calls at an 8% hit rate, 6287 of the misses purely because the constraints differed rather than anything being dirty. Give the dry measurement its own cache slot, as Flutter does with _cachedDryLayoutSizes, and let dryness propagate: performLayout measures its children through layout(), so without a flag the dry pass writes dry constraints into every descendant's real slot and the following real pass misses on all of them - only the root would have benefited. The subtlety that makes this correct: performLayout is NOT side-effect free, it writes child offsets. A dry pass that actually runs leaves those offsets at dry values, so the real pass must not be allowed to hit its cache and keep them. It drops its own real slot only - not its ancestors', which would escalate back into the whole-tree invalidation this exists to avoid. Caught in the simulator: without it the study card's caption rendered at the top of the card instead of the bottom. BuildOwner.traceFrames() records what a build flush costs and how much of the layout pass the cache absorbs, since "the UI feels slow" is a question about where the frame went. Result: worst frame 615ms -> 229ms, layout calls 7635 -> 4179, hit rate 8% -> 30%. Better, NOT fixed - 229ms is still ~14x the frame budget, and the remaining cost has moved out of layout-call count into the revalidate itself.

In Codename One a finished layout is finished; revalidate goes to the Form root and lays the whole hierarchy out again, so a setState on one leaf re-laid out the toolbar, the side menu and every other container on the form. Mark this host's own subtree and call layoutContainer(), which does only the work a change inside this host can have affected. The Flutter pass is tight against the host's bounds, so the host does not change size and its parent has nothing to redo. This is the right scope, but it is NOT where the time was going: the frame stayed at ~200ms, because the cost is our own constraint pass over the host subtree rather than Codename One laying out the rest of the form. Recording that here so the next attempt does not re-try this avenue expecting a win. Adds per-class self-time attribution to the layout pass (parents would otherwise swallow their whole subtree and every profile would blame the root), reported through frameStats as the hottest element classes. The remaining ~200ms is roughly 4000 layout calls, far too slow for constraint arithmetic, so the next question is which element's performLayout is expensive - and now the runtime can answer it instead of being guessed at.

The Flutter constraint pass was never the expensive thing. Per-class self-time attribution puts it at ~2ms across ~4900 boxes - TextRenderElement 2ms and every other element class rounding to 0. All the rest was Codename One being told to redo work it had already done and cached. revalidate() begins with setShouldCalcPreferredSize(true), and that recurses down every child container discarding CN1's cached preferred sizes, so every Label re-measured its text on every frame. Preferred size is cached precisely so that does not happen. Switching to layoutContainer() kept the same mistake, because I was still calling setShouldCalcPreferredSize(true) to mark the subtree - which is why that change did not move the number. A Flutter build flush needs neither. Our own layout writes every component's bounds absolutely, so running the host's Layout directly is the entire job: no invalidation, no CN1 measurement, no walk of the form. A component whose content actually changed already invalidates itself - Label.setText does - so blanket invalidation could only ever discard measurements that were still valid. Verified in the simulator: the category expand still reveals its rows and the home screen renders identically to the reference capture.

We drew the rounded surface but never clipped the child, so the image painted square corners over it and the card read as a plain rectangle against the reference's rounded one. Material already owns a nested pane (it is an EffectRenderElement), so the clip just needs the right shape in the right space: the path is built from the pane's PARENT-RELATIVE bounds, because the Graphics has already accumulated its ancestors' translation. The earlier attempt at this built the path from getAbsoluteX/Y, which is the same double-offset that made CustomPaint draw nothing, and is why it "cut away most content" and was reverted. setClip(Shape) replaces the clip rather than intersecting it, and the card sits in a horizontally scrolling carousel that is already clipping us, so replacing outright would let a half-scrolled card paint outside its viewport. Intersecting unconditionally is not the answer either: GeneralPath.intersection() does not survive a path that lies entirely inside the rectangle, and going through it in every case cut the icons out of every category row. Intersect only on genuine overflow; use the plain rounded rect otherwise. Verified against ref-flutter-home.png: the card now has rounded corners and the category rows keep their icons.

TEXT: TextStyle.letterSpacing was parsed and then dropped - only RichText ever read it - so every header and button caption rendered tighter and lighter than the reference, which is most of the "typography is wrong" impression. Codename One draws a whole string in one advance and has no tracking of its own, so the glyphs are now advanced individually, and both the measurement and the wrap account for the added width. Flutter puts the gap BETWEEN glyphs - n-1 gaps for n characters, nothing trailing the last - and being one gap out is a whole space of drift on a short label, so the arithmetic is pinned by LetterSpacingTest. CAROUSEL: PageView never snapped ("one-page snapping is deferred"), so a released swipe stopped wherever Codename One's momentum ran out and the carousel sat between two cards. Snapping cannot happen in pointerReleased because the momentum has not run yet; the pane now waits for the scroll position to stop changing and then settles onto the nearest page with an eased Motion. Verified: after a swipe the card comes to rest at the canonical 296-wide, inset-40 position instead of mid-drag. Residual, measured not guessed: the settled page is offset about 28 logical px from centred - the snap lands on a page boundary but does not account for the leading slack gap that centres a page when viewportFraction < 1. The mechanism is right, the target needs the slack term.

Our PageController never notified and always reported its initial page, so `position.haveDimensions` stayed false and every builder took the fallback branch forever: the card you were looking at rendered at a fixed 0.868 of its size while the off-screen neighbour rendered full size - exactly inverted. Measured, not guessed. The settled card was 771 device px against a slot of 888 (0.868), and Curves.easeOut(1 - 1*0.3) = 0.873 - which identifies the frozen branch precisely. Confirmation after the fix, using the card's top edge (the viewport clips the bottom, so height is not usable): the neighbour's top moved from 392 to 450 and the centre card's from 500 to 419, i.e. the two swapped which one is shrunk. The controller now carries the scroll state. The render element attaches on mount, publishes the pane's offset as a fractional page from layout and from a CN1 ScrollListener, and detaches on unmount. The listener is the only usable hook: CN1 assigns scrollX directly while a finger drags, so overriding the setter would miss every drag frame. Notification is guarded on the page actually moving, so a scroll event on a frame where nothing changed does not dirty the builders. Two further gaps the new tests found rather than I did: - onPageChanged fired for the page the view STARTED on; Flutter reports transitions only. - initialPage was inert - the pane opened on page 0 regardless. Also honour pageSnapping. It defaults to true, but it is genuinely opt-out and the gallery carousel passes false, so unconditional snapping was a fidelity bug of its own. Not part of the carousel, but it blocked the build: dart-runtime and flutter-runtime set only 17, and the parent's pluginManagement pins an explicit 1.8. The inherited explicit value beats this module's maven.compiler.* properties, leaving javac on -source 8 and failing against the Java 17 sources. Both poms now state source/target explicitly.

So any rebuild of any widget invalidated the geometry of the entire page. The carousel made it visible because it rebuilds a Transform per card per scroll frame: six cards dirtied the Scaffold, the category list and everything else, and each drag cost a full-page relayout. Measured on the running app with bench_frames, one flush: worst frame 210ms -> 0ms revalidate 210ms -> 0ms layout calls 1241 -> 496 constraint miss 120 -> 0 hot class MaterialRenderElement 461ms/24 calls -> none above 0ms Page scrolling is now 91 layout calls, all of them cache hits. Note MaterialRenderElement was never the culprit despite topping the profile: it is an effect wrapper, so it was being charged for the subtree layout it rooted. The cost was the invalidation, not the element. Flutter draws this line as markNeedsPaint vs markNeedsLayout. Effects are paint wrappers whose performLayout takes its size straight from the child, so no configuration of the effect itself - a Transform's scale, a Material's colour or elevation - can move anything, and EffectRenderElement now reports that. It is deliberately about this element only: when a rebuild replaces a CHILD, that child's own update still marks layout and the walk passes through as before.

Display.setTimeout allocates a java.util.Timer - a whole thread - per call, so this created and abandoned one thread per animation frame. Worse, measured in the simulator that path does not deliver anything near the delay asked for: CN.setTimeout(16) -> 303ms mean (min 296, max 331) CN.setTimeout(1) -> 283ms mean (min 279, max 292) a fixed ~290ms whatever is requested. At that rate a 300ms curve reaches t >= 1 on its FIRST tick, so animations jump to their end value instead of tweening. Now a single com.codename1.ui.animations.Animation is registered on the current Form, which is the EDT's own frame clock: a Form with a registered animation stops the EDT sleeping (Display.shouldEDTSleep consults Form.hasAnimations), so animate() runs once per frame while anything is animating and the driver deregisters itself when the last one finishes. It re-attaches if the form changes underneath it, which the timer version had no equivalent of. animate() returns false deliberately: advancing a controller notifies its listeners, which mark the affected elements dirty and repaint just those, so returning true would add a full-form repaint per frame on top. NOT a complete fix for the symptom that prompted it. Tapping a category still expands in a single frame - one blit for the whole transition - so either that animation does not run through AnimationController at all, or something downstream of it collapses. The timer clock was real and is gone; it was not the only cause.

A PADDING change is what Component.styleChanged answers with revalidateLater() on the parent, so laying out a Form with a safe-area container queued a revalidate of the whole Form, which laid it out again, which queued another. It could never converge: the padding is reverted before anything can observe it as settled. An idle app hides this, because the EDT sleeps and the treadmill turns once per wake-up. It bites the moment something keeps the EDT awake - any drag, any animation - which is every case where frame time actually matters. Measured on the Flutter gallery in the JavaSE simulator, ~200ms of every EDT pass went to Form.flushRevalidateQueue against ~15ms of real painting. Scrolling ran at 4.66fps; it now runs at 61.93fps, which is CN1's own 66fps framerate cap. The fix is snapToSafeAreaQuietly(): suppress change events across the snap and restore whatever suppression state the caller had. Also adds the instrument that found it, since three plausible paint-cost theories died before it existed. -Dcn1.edt.trace=true breaks each EDT pass into idle / events / revalidateQueue / paintDirty / animations / serialCalls and reports the totals once a second, plus a line for any single revalidate over 4ms. Off by default, one boolean test per pass when off. SafeAreaRevalidateLoopTest covers the invariant. Being straight about its reach: only measuringASafeAreaContainerAnnouncesNoStyleChange actually fails without the fix - that is the path that was firing in the app. The doLayout-path and convergence tests pass either way in the headless harness; they are there to guard the sibling path, not because they currently bite. TestCodenameOneImplementation had listenSocketLoopback and isLoopbackServerSocketAvailable defined twice (a merge artifact that would not compile); the duplicate pair is removed, keeping the richer loopbackSupportedOnlyOnFirstQuery implementation. Suite: 4757 tests, 4 failures - all four pre-existing on this branch and unrelated (CSSThemeBorderRadiusTest, RoundRectBorderCssBoxModelResourceTest), verified by re-running them with these changes stashed.

Everything between that call and the clock reaching the controller - the setState it triggers, the build that follows, the paint of that build - was therefore charged to the curve. On the gallery's category expand that gap measured 223ms against a 200ms duration, so the very first tick already had t >= 1 and the animation only ever showed its end state. It looked like a broken clock; it was a stopwatch started too early. Flutter's Ticker records _startTime inside the first frame callback for exactly this reason. Doing the same makes the first tick define t = 0 and the curve play in full regardless of how expensive the frame that started it was. The category expand now runs 13 frames over its 200ms with a 17ms mean gap (~59fps) instead of a single frame. PageViewRenderElement.awaitMomentum no longer polls with CN.setTimeout(50). Display.setTimeout allocates a java.util.Timer thread per call, so one flick spun up and abandoned a thread per poll, and a 50ms poll cannot see the frame momentum actually stops on. It now rides the form's animation loop - which the gliding pane is already keeping awake - and notices the stop on that frame. A new pointerPressed cancels the watcher so a fresh touch cannot get a snap fired under it. Adds the counters that made this diagnosable, surfaced through the existing BuildOwner.traceFrames switch: ticks, runs, min ticks per run, mean/worst gap, and worst first-tick lag. Ticks-per-run is the number that distinguishes "snaps to the end" from "plays choppily" - both look the same on screen. 168 tests green.

A push that arrives from OUTSIDE the tree - a deep link, a notification tap, a test harness - has no context, and passed null: the route was then mounted with no ancestors at all, so the first Theme.of, MediaQuery.of, Localizations.of or provider lookup inside it returned nothing and the page died on the null check. Every gallery demo route reached this way threw "Null check operator used on a null value" before rendering anything. MaterialApp now marks where the app's root navigator sits - below its localizations scope and above the app content, which is where Flutter puts it - via Navigator.RootScope, and a context-less pushNamed inherits from there. Pushing on the root navigator is exactly what a context-less push means. Falling back to the app ROOT element instead is not sufficient and was the first thing I tried: MaterialApp's Theme and Localizations live in what it BUILDS, so they are below the root, not above it. The chain has to start below them. FlutterUI.currentContext() exposes the showing tree's root for the case with no MaterialApp at all (a bare FlutterUI.wrap tree). It reads the element off the Form rather than a static, so a popped route cannot leave a stale answer behind. Verified against the gallery: demo routes that previously threw before painting now mount and scroll at 62-65fps with a worst frame of 18.9ms, which is CN1's own framerate cap - no dropped frames. What remains on those pages is missing widgets, reported as unimplemented rather than thrown: OpenContainer paints nothing, and the progress indicators reserve an empty box, so they have no animation to be smooth or otherwise. 168 tests green.

SCROLLBARS. Flutter draws a scrollbar only where the tree asks for one by wrapping a scrollable in Scrollbar/RawScrollbar; a bare ListView, SingleChildScrollView or PageView draws none. Ours defaulted to CN1's scrollbar, so every scrollable in a transpiled app carried a bar Flutter never put there. hideScrollbar() now walks for a Scrollbar ancestor, which is exactly the relationship Flutter uses - Scrollbar WRAPS the scrollable it decorates. CARD GEOMETRY. An effect's nested pane carries its own FlutterRootLayout, and Codename One runs that layout independently, deriving constraints from the pane's CURRENT component size - which is the Flutter-assigned one only after position() has written it, and before that is whatever CN1 last put there. The study card was therefore laid out against its own unconstrained preferred height (272dp) instead of the carousel's 240dp viewport: 888x720 where Flutter gives 888x624. That is why its caption was clipped mid-descender and its bottom corners came out square. The effect now remembers the constraints the Flutter pass gave it and hands those to the nested pass, so CN1 reproduces that geometry instead of re-deriving it. Verified against the running app: the card is now 888x624 and sits inside its viewport. THE SETTINGS MENU. Two frozen widgets between the button and the panel. ValueListenableBuilder was a StatelessWidget that read the value once and never subscribed, so a ValueNotifier changing moved nothing. PositionedTransition resolved its RelativeRect once when its element was created - harmless when an animation rests at its END value, fatal when it rests at its START: the settings panel begins one full screen-height ABOVE the viewport and slides down, so a panel that never moved simply stayed off-screen. Tapping settings ran the entire toggle - notifier flipped, controllers animated, 224 elements rebuilt - and produced no visible change, which reads as a dead button. Both now listen. PositionedTransition stays a PositionedRenderElement rather than composing one, because StackRenderElement decides what is positioned by looking for that type. Verified in the running app: the settings panel slides in and back out. Also adds -Dcn1.flutter.layout.trace=, which prints each element's constraints in / size out and whether the pass was dry. The card bug was invisible to screenshots and to component bounds; the trace named it in one run after several wrong inferences from pixels. 172 tests green, including 4 new ValueListenableBuilder tests - 2 of which fail without the subscription.

InkWell and InkResponse rendered as a bare transparent overlay - the splash and highlight were never implemented - so a transpiled app had no touch feedback at all. Tapping anything felt dead, which is the single most noticeable thing missing next to a real Material app. InkFeedback paints both halves, because with only one of them it reads wrong: the HIGHLIGHT is a flat wash over the target that says "pressed", the SPLASH is a circle from the exact touch point that says "here". It rides Codename One's animation loop rather than an AnimationController - this is component-level feedback with no widget of its own, and it has to survive a rebuild of the subtree it belongs to. A drag cancels the ink outright, as Flutter does, so a scroll that starts on a row does not leave a splash on a moving list. The one non-obvious bug worth recording: the first version drew nothing at all, with press firing and paint being called. Component.paint receives a Graphics that has ALREADY accumulated every ancestor's translation, so it draws in PARENT-relative coordinates; using getAbsoluteX/Y put everything at roughly twice the offset and the containment clip then intersected to nothing. Established by painting opaque red and still seeing nothing, which ruled out colour and alpha and pointed at geometry. Opacities are Material 3's state layer (~6% highlight, ~7% splash, ~13% where they overlap). The first pass at 9%/16% read as the row changing colour rather than as ink. PIXEL RATIO. Dp derived Flutter's logical pixel from CN1's density BUCKET, which is a DPI approximation - a 460ppi iPhone lands in DENSITY_560 and maps to 3.5, while UIScreen.scale on that same phone is 3. Measured against native Flutter on one iPhone 17 Pro: the study card came out 345.3 x 242.7dp where Flutter draws 296.0 x 208.0, exactly 7/6 on both axes. New CodenameOneImplementation.getDevicePixelRatio() (0 = not reported, keep the old bucket derivation), overridden on iOS off the resolution table it already maintains. Density and scale factor are genuinely different questions and the javadoc on both says so, because conflating them is what caused this. 172 tests green.

What it established, including a correction of my own first reading: - Through bench_paint (which renders OFFSCREEN, into an Image) the clip costs 56.62ms/frame against 1.65ms without it. That is the iOS port's MUTABLE NativeGraphics path, which flattens the rounded rect to a polygon in Java and marshals every vertex per call. - On screen it makes no difference at all: the same carousel drag measures 27.78fps with the clip and 26.94fps without. So the clip is expensive only where bench_paint looks, and is NOT what makes the carousel slow. The two iOS NativeGraphics implementations (mutable vs global) do not have the same performance, which means bench_paint cannot stand in for on-screen paint cost - the same trap as measuring a gesture inside one EDT slot. The carousel's ~36ms frames on iOS remain unexplained: our build and layout during that drag total ~1ms, and it is not the clip. Whatever it is sits in on-screen painting of the scaled cards, which neither bench_paint nor bench_frames can see.

A carousel that rebuilds its cards per scroll frame therefore re-scaled every card's full-size artwork every frame. Caching on (source image, box, fit) makes it happen once per actual change. Being straight about what this did NOT do: it was my candidate for the iOS carousel running at 27fps, and it did not move that number at all (26.9 before, 26.6 after). The change is still right on its own terms - resampling a bitmap per frame to produce an identical result is waste on any platform - but it is not the carousel's problem, and I am recording that so the next person does not re-derive the same dead end. Two hypotheses now ruled out for the carousel by measurement: the Material shape clip (27.8fps with, 26.9 without) and per-frame image rescaling (unchanged). Build and layout during that drag total ~1ms. The EDT phase trace puts the time in on-screen paintDirty: 398ms across 36 passes, ~11ms each, with a worst pass of 151ms - the spikes lining up with new cards coming into view. 172 tests green.

CodenameOneImplementation.paintDirty treats that case specially: it sets the flush region to the ENTIRE screen, calls paint() on the animation - which paints nothing in both of these, since the drawing is done by the component - and then flushes all of it. Every frame of a running animation therefore pushed a buffer that frame had never drawn into. That is the flicker. Both now return false and repaint the component instead, which queues it with a real dirty region so only the affected area is flushed. Galling detail: FrameDriver already returns false for exactly this reason and says so in a comment I wrote. I then did the opposite in InkFeedback, and found the same mistake sitting in the PageView settle animation next to it. Also expires the ink on the clock rather than in paint(). paint() only runs while the component is being painted, so ink on something that scrolls out of view or stops repainting would have stayed "active" forever, keeping its clock and its repaint alive for the life of the form. Verified on the simulator with the EDT phase trace: before, a tap left the EDT painting continuously at 61 passes/sec with ~9.5ms of paint each; after, it settles so quickly the once-a-second trace never emits a line. Idle was already clean in both. List scroll 61.3fps, ripple unaffected. 172 tests green.

It settles the carousel question: transform ON : 19.0fps and 23.8fps, p95 ~195ms transform OFF: 62.6fps and 57.1fps, p95 19-26ms Same drag, same build, one property apart. Transform.scale - six cards, each setting and restoring a matrix per frame - is the entire difference between the carousel and a plain list on iOS. What it is NOT: the matrix state change itself. CN1MetalSetTransform stores a matrix and returns, and the native op is only queued. The cost is downstream of having a non-identity transform active while the subtree paints, and I have not identified it further. Worth noting before anyone optimises for this: the numbers are from the iOS SIMULATOR, where Metal is emulated. Transform-heavy paths are exactly the kind of thing that is disproportionately slow there, so this needs confirming on real hardware before concluding the carousel is slow on devices. This closes out the search that had already ruled out, by measurement, the Material shape clip, per-frame image rescaling, the full-screen flush, and first-paint image decode. 172 tests green.

Codename One repaints a single component by painting its ancestors' BACKGROUNDS and then the component. That is sound in an ordinary widget tree, where a child is contained by its parent and siblings do not overlap. This runtime is the opposite by design: components are flat, absolutely-positioned siblings that deliberately overlap - a card's artwork, the ink overlay on top of it and the gesture target are all peers in one host container, and nearly every one of them has a transparent background. Repainting one of them erases whichever peers share those pixels, and the flush carries that half-drawn result to the screen. Content vanishing mid-swipe and torn artifacts are exactly that. markNeedsPaint - which every paint-only update goes through, including the carousel's per-frame Transform updates - now repaints the element's rectangle on the host CONTAINER, which redraws every sibling intersecting it in z-order. The ink does the same on press, release, cancel and each frame. This also reframes the carousel finding. Turning Transform off did make it fast, but a scaling transform draws smaller or larger than the component's bounds, so it is also the case that maximises the mismatch between what is cleared and what is redrawn. Whether the remaining cost is real work or repeated repair of torn frames is now worth re-measuring rather than assuming. 172 tests green. Not yet verified on iOS - the build is still running.

A press whose release never arrives - a component removed by a rebuild mid-press, a gesture cancelled somewhere that does not route back here - left the clock asking for a repaint every frame for the life of the form. Once the splash has covered the target and the highlight is fully in there is nothing left to animate, so the clock detaches and the static ink stands until release; release re-attaches it for the fade. Honest about the provenance: this is defensive, not diagnosed. The app became unresponsive on its MCP channel at the end of a long automated session in which I had been leaving presses deliberately held (a test hook), and an unbounded per-frame repaint is a plausible contributor. I did not prove it was the cause - the app was too wedged to introspect - but an animation that can run forever if a release goes missing is worth closing on its own merits. 172 tests green.

That is a general polygon clipper, and a half-scrolled card overflows its viewport on every frame of a drag, so it ran per card per frame. The sample caught the EDT parked in usleep inside cn1BibopMaybeGc, under allocArray, under ShapeUtil.intersection, under paint: painting was driving the garbage collector, which is what the stalls and the half-drawn frames were. Intersecting a rounded rect with an axis-aligned rect needs no clipper - the result is the intersected bounds, rounded at whichever corners the clip left intact - so compute it directly into a reused path. It is also more correct: the clipper did not survive a path entirely inside the rectangle, which is why this used to need a special case to stop it cutting the icons out of every category row. StackRenderElement implemented only StackFit.loose and silently ignored the widget's fit. StackFit.expand is how a Stack tells its children to fill it, and the gallery's card is exactly that shape - Stack(fit: expand) over an image that separately declares its own height. The Material elevation shadow passed shadowSpread a value in MILLIMETRES that worked out to ~23px at this density, with shadowY hard over at 1 rather than centred. RoundRectBorder reserves that spread inside the component and draws the surface displaced by it, so the card sat 23px clear of its own box - a grey band along its top edge and content spilling past its bottom. Measured on the iPhone 17 Pro simulator, drag with movement verified: worst frame 104ms -> 31-68ms, and a sustained 8s drag now samples zero ShapeUtil.intersection and zero cn1BibopMaybeGc frames. Also fixes the side-by-side script, whose no-argument form launches without building: it now says so and offers cn1build. A silent stale launch is indistinguishable from a fix that did not work.

Three separate causes, each found by a device experiment rather than by reading: 1. The surface was drawn by a RoundRectBorder, i.e. as the component's BACKGROUND - and a background is painted before paint() runs, so it landed outside the rounded clip and squared the corners off from behind. A Material now paints its own surface from the same path it clips its subtree to, which is also what Flutter does. Dropping the per-paint RoundRectBorder took the carousel from 48-55fps to 57-60 and its worst frame from 68ms to 34ms. 2. The clip path was built with quadTo, so GeneralPath.isPolygon() was false. The ports branch on exactly that to decide how to hand a clip to the GPU: a polygon goes to the Metal stencil, anything else to a texture mask, and the Metal texture-mask path falls back to the shape's BOUNDING BOX. Corners are now short line segments - under two pixels each at a 10dp radius. 3. Even then the artwork stayed square, and a device A/B settled why: a fillRect through the rounded clip comes out ROUND, the image drawn through the same clip does not. That is a port bug in the Metal backend - a textured quad escapes the polygon stencil - and it needs a GPU frame capture, not guesswork, so it is recorded rather than chased here. An image that exactly fills a clipping Material now rounds its own bitmap when it is scaled, which does not depend on the clip and costs nothing per frame. The elevation shadow moves with the surface: fillShapeShadow where a port has it (a single accelerated draw, no retained bitmap), else four fading rounded rects. Not a cached shadow image - caching one per card is what made these same cards a RAM and jank problem on Android. Also restores the bench harness (tools/env.sh, tools/mcp.py, tools/moves.py) into the project. It lived in a temp dir and was reaped between sessions, which cost an hour of rebuilding the toolchain and the MCP client from scratch.

Two motions with a full stop between them, which is what it looked like. Flutter runs exactly one simulation from the moment of release. PageScrollPhysics picks the target from the position AND the release velocity - past the velocity tolerance you go to the NEXT page even from a barely-moved carousel, below it you fall back to the nearest - and then springs to it. That is now what happens: the velocity is read before super consumes the drag state, Codename One's decay is cancelled, and a critically damped spring runs to the Flutter target. Nothing could stop a settle once it started, either. A finger landing mid-settle, or a second flick arriving before the first finished, left the old animation running alongside the new one; both wrote the scroll offset every frame and whichever finished last won, which leaves the carousel resting between two cards. A settle is now cancellable and exactly one runs at a time. Cancelling the built-in decay needs a public way to do it, so Component gains stopScrollMomentum() - an addition, and the narrow form: unlike clearDrag() it leaves an ancestor scrolling on the other axis alone. WORTH KNOWING: the gallery's own carousel passes pageSnapping: false, so none of this runs for it - it scrolls freely, and always did. Confirmed on the device (the release reports snapping=false), so anything odd in how THAT carousel comes to rest is in the scroll physics, not here. A note at the top of the class says so, to save the next reader the same detour.

The new behavioral case is the gallery's own animation math, lifted verbatim from pages/home.dart, printed as integers: the per-card Transform.scale curve across a four-page sweep either side of centre, the staggered entrance (Interval + Tween + Curves.ease) at two delays, and the carousel's slide-in. expect.txt is not hand-written. benchcn1/tools/dart-reference.sh runs the SAME main.dart on the real Flutter SDK via `flutter test` and captures its output, so the file records what Flutter actually does rather than what we think it should; BehaviorTest then transpiles the same file, runs it on the JVM and diffs. All 153 lines agree, and a deliberately loosened CUBIC_ERROR_BOUND makes the case fail, so the test can tell the two implementations apart. That is a NEGATIVE result worth having: the card-scale curve and the entrance stagger are identical to 1e-5 of scale - about three thousandths of a pixel on a 296dp card - so neither is the source of anything odd in how the carousel moves. Two things had to change to let a case touch a widget API. The harness resolved against the embedded stub set only, which is the built-ins plus material, so anything a runtime module declares for itself (Curves, the animation family) was unresolvable; it now resolves against the stubs published by the jars on the classpath, the way the mojo does, with flutter-runtime added test-scope. That immediately exposed a real emitter bug. A sealed type's permits clause used the DART name of each subtype rather than the emitted one, so a subtype whose name collides with a stub class - emitted library-qualified - was permitted under a name that does not exist. Not niche: the Flutter stubs declare Rect, Size and Color, all reasonable names for an app's own sealed types. The m5_patterns case has a Rect and now covers it.

BouncingScrollPhysics was an empty class before this; it now implements Flutter's algorithm and reproduces all 64 reference lines, and a 0.52 -> 0.60 change in the friction constant makes the case fail, so the test can tell the implementations apart. The interesting part is what fell out of it. Codename One compresses an over-edge drag in closed form, c*x*D/(c*x + D), while Flutter damps each drag delta by 0.52*(1 - overscroll/D)^2 and never mentions total distance. Integrating the second gives the first with c = 0.52. They are the SAME curve, and the whole difference is the coefficient: Codename One ships UIScrollView's 0.55, Flutter uses 0.52. So the overscroll is one theme constant, not a reimplementation. RubberBandParityTest integrates the physics and checks the closed form really does fall out (and converges as the step shrinks); RubberBandCoefficientTest, over in core-unittests where a headless Display exists, checks the framework's own rubberBandCompress against that closed form at both coefficients. Writing that test then exposed a far worse bug. A theme constant is only a constant if its key carries the leading '@' - buildTheme strips that prefix to decide what is a constant and what is an ordinary style property, and both are accepted in silence. installFlutterScrollPhysics had never used it, so DecayMotionScaleFactorInt has been stored and ignored the entire time it was believed to be matching the fling distance to Flutter's friction simulation. getThemeConstant just kept returning the framework default of 950, i.e. flings have been travelling 1.9x too far on every build so far. Both constants are now prefixed, and ScrollPhysicsPropsTest asserts the prefix on every key, since the failure mode is silence rather than an error.

ListView.builder declared four parameters. The gallery passes shrinkWrap: true - which is how a list inside a Column says "size to your content" - and the transpiler DROPPED it, silently, because the factory had nowhere to put it. No diagnostic, no runtime complaint; the list simply took the whole height it was offered. Confirmed on the device: with the parameter accepted, the options box goes from 1152px (the 384dp cap it was given) to 960px (the height of its own content). physics, scrollDirection and controller were being dropped the same way and are now accepted too. Worth stating plainly: any named argument a stub does not declare is discarded without a word, so this is unlikely to be the only place it happens. Making the transpiler reject unknown named arguments instead would surface the rest at build time, which is the obvious next lever for closing the gap with the demo. The stubs exist in TWO copies - one embedded in the transpiler, one shipped by flutter-runtime - and only updating one leaves the goldens compiling against a signature nothing else has. Both are updated here; the duplication is a trap in its own right. Also adds a behavioral case for the default TextTheme, since Material code reaches for those slots with `!` constantly and an empty one turns every such call site into a TypeError that makes a widget vanish. Both implementations agree all fifteen slots are non-null, so that contract is now pinned. It deliberately does NOT pin the metrics: a bare ThemeData in Flutter leaves fontSize null and resolves it from Typography later, while this runtime fills in the M3 default immediately, and that difference is not one to remove. Error reports now carry the first frames of a throwable's own stack. ParparVM supplies none, so this only pays off on the desktop and JS ports - which is where the remaining settings TypeError will have to be caught.

It is now reported. Over the gallery that is 90 arguments the app asks for and does not get, which is the list to work through; benchcn1/tools/inventory.sh produces it (and the runtime half, which is whatever the app reports through FlutterErrorReport). Worked the top three, 90 -> 49: - package (21). Image.asset had no such parameter, so the qualifier was dropped and the asset resolved to a path with no file at it - a blank image, silently. AssetImage already did this correctly; the qualification is now shared between them so every way of naming an asset resolves to the same file. - letterSpacing (18) and height, on the GoogleFonts family. TextStyle itself has supported letterSpacing all along; only the stub's parameter list was short, so every font call in Rally, Crane and Shrine lost its tracking. - letterSpacing/height on the TextStyle constructor, same cause. The remainder is a long tail on ColorScheme (secondary/background/error/ *Container), ThemeData's sub-themes (textSelectionTheme, bottomSheetTheme, bottomAppBarTheme, primaryIconTheme, pageTransitionsTheme, inputDecorationTheme) and Image (cacheWidth, gaplessPlayback, excludeFromSemantics) - concentrated in the four studies, which is where the demo is least complete. Note the stubs live in two copies, transpiler-embedded and flutter-runtime, and both must be edited together or the goldens compile against a signature nothing else has.

Dart rejects an undeclared named argument, so accepting one was our divergence from the language, and the way we diverged was the worst available: the value was dropped and the app looked like it worked. The gallery transpiles clean with the gate on. Closing the 90 took the runtime API and its stubs, not the demo: - ColorScheme.light/dark took NO parameters at all, so a scheme written out role by role - which is how all four studies define their palettes - was built entirely from the default seed and every colour was discarded. 13 of the 90. - ThemeData.copyWith was missing the sub-themes a study overrides when it re-skins the app (bottomAppBar, bottomSheet, inputDecoration, primaryIcon, pageTransitions, textSelection, indicatorColor), so a study's own styling was dropped and it rendered with the base Material theme. 11. - GoogleFonts took only size/weight/colour, losing letterSpacing, height, fontStyle and - worse - textStyle, which is the BASE the rest are layered onto, so the text kept the font and lost everything else. 24. - Image.asset lost package (fixed earlier), excludeFromSemantics, gaplessPlayback and the cache hints. ListView/GridView lost restorationId, primary, physics, itemExtent. BorderSide lost strokeAlign. Missing types the arguments needed: TextSelectionThemeData, PageTransitionsTheme, PageTransitionsBuilder (with SharedAxisPageTransitionsBuilder now extending it, as in Flutter) and FontStyle. Two emitter bugs surfaced the moment those arguments stopped being dropped, both in code that had never been reachable: - `SomeEnum.values` emitted as a field access. Dart exposes it as a getter returning a List, Java as a static method returning an ARRAY - so the Dart spelling names nothing, and the bare values() hands an array to code that then calls Dart list members on it. Now wrapped, so indexing and iteration work. - The gate's own first cut required Param.named, which is not set for the `required T name` form, and reported arguments that are in fact declared. A false positive is fatal for a diagnostic that becomes an error, so it matches on name. The settings menu is still not fixed - its TypeError survives all of this.

The origin capture added earlier finally paid for itself on the desktop simulator, where ParparVM's empty stacks are real ones: _SettingsIcon's tap handler, asserting GalleryOptions.resolvedTextDirection() is non-null. It was null because the locale was. The gallery's locale getter falls back to a global device locale, and that global is written by the app's own localeListResolutionCallback - which this runtime never called. MaterialApp picked a locale by taking the first supported one and never asked the app, so anything derived from the device locale stayed null and the first `!` on it threw. effectiveLocale now follows Flutter's order: an explicit locale wins, otherwise the app's callback chooses from the device's locales, otherwise the first supported one. Asking the callback is the point - it is where an app learns what the device asked for. Settings now opens clean on both the desktop simulator and the device. Still open, and now well characterised: the expanded options list builds its five RadioListTiles and lays them out (the box is exactly 5 x 64dp) but produces no components, and throws nothing at all on either platform. Not a TypeError, not a dropped argument - the subtree is built and mounts nothing.

The Dart is `_timeDilationTimer?.cancel()` - it cannot throw. We emitted `this._timeDilationTimer.cancel()`, with the null guard simply gone. `a?.b` was shorted correctly all along. `a?.m()` honoured the `?.` only when the receiver happened to be function-valued (the SAM `call` path); every other receiver fell through to a plain, unguarded invocation. Silent until the receiver is actually null, and that timer is null until something has been dilated - so the first toggle of the switch was the first time anyone hit it. Method calls now take the same shorting as property reads: the receiver is lifted into a temp and the call runs on the non-null temp, with the temp's nullness shorting the call and any trailing selectors. A void call in statement position becomes an `if` rather than a ternary, since void cannot be a ternary's value. Pinned by dart_null_aware_calls, whose expectations come from running the same file on the Flutter SDK: the call itself, statement position (where the missing guard actually bit, because nothing forced a value context), chains that short the whole rest, mixed property/call chains, that a shorted call really does NOT invoke the method, ?. combined with ??, and the function-valued case that already worked. Twelve lines, all agreeing. Slow motion no longer throws and the app stays responsive. The switch's visual state still reverts to off after a toggle, which is a separate problem - the model's equality and copyWith argument order both check out, so it is further down in how the new model reaches the widget.

That is the gallery's whole options model, the theme, and provider, and it is why the slow-motion switch snaps back - the page that renders it is never rebuilt, so the old value is re-applied over the user's. InheritedElement now exists and lookups register with it. The NOTIFICATION is gated behind cn1.flutter.inheritedNotify, off by default, because turning it on empties the settings page - inline during update(), and equally when deferred to a serial call past the flush. A blank page is worse than a stale switch. The census (cn1.flutter.inheritedCensus) says why, and it is not the notification mechanism at fault. ModelBindingScope has 14 dependents, and the first is the top-level Builder that returns the MaterialApp. Rebuilding that rebuilds the whole app, and this runtime does not carry the Navigator's route state across such a rebuild - so the settings route is torn down and what is left is an empty page. Flutter survives it because reconciliation reuses the Navigator element and its state. So the next fix is in reconciliation, not here: a MaterialApp rebuild must preserve its Navigator and the route on screen. Until then the registration is harmless and the mechanism is one property away from being live. Tests are shaped like the real tree this time - StatefulWidget publishing through an InheritedWidget to a consumer several layers down - because the flat version of these same tests passed while the device rendered nothing.

The result is specific: SettingsPage notified -> settings page intact, slow-motion switch STICKS AnimatedHomePage notified -> intact CarouselCard notified -> intact ApplyTextOptions notified -> page blank LayoutBuilder notified -> page blank So the inherited-widget mechanism is right, and the switch genuinely works once its page is told to rebuild. What is broken is narrower than "notification": rebuilding ApplyTextOptions or LayoutBuilder destroys the subtree. Both wrap most of the app - ApplyTextOptions in a Directionality/MediaQuery, LayoutBuilder in a whole page - so whatever the defect is, it is about a rebuild replacing a subtree that owns components or a nested RenderHost, not about who asked for it. Notably it is NOT the top-level Builder that returns the MaterialApp, which was the previous suspicion: notifying it alone leaves the page intact. The notification therefore stays behind cn1.flutter.inheritedNotify while that rebuild defect is fixed; with it off the app is exactly as before. The two symptoms - the switch reverting and the settings options staying empty - are unchanged, and both are one working rebuild away. Also: no String.split in this module. ParparVM's Java API has no regex-based String methods, so it compiles on the desktop and fails iOS translation with an undeclared-function error.

With the test-jar on flutter-runtime's test classpath, surefire fails discovery outright ("TestEngine with ID 'junit-jupiter' failed to discover tests") and the whole suite runs zero tests, with no detail in the dump. That is a dependency problem to work out - most likely something the harness needs at discovery time that the test-jar alone does not bring - and leaving it wired would trade 204 running tests for none, so the flutter-runtime pom is unchanged for now.

An element records the RenderHost it was mounted into, and the build flush revalidated only those. But a rebuilt subtree can contain scroll panes and effect panes carrying hosts of their OWN, and those are what hold the components - so a nested host was left with children it never laid out. The scaffold survived, its contents did not, and nothing threw. flushBuild now collects the hosts inside each rebuilt subtree as well. With that fixed, inherited-widget notification is on by default and both symptoms are gone, verified in the simulator: - the slow-motion switch toggles on, stays on, and toggles back off - expanding a setting shows its options - all five radio rows, correct one selected - where the box was empty before Both were the same cause. The switch's page and the options list live inside nested hosts, so neither could ever be rebuilt into place. Worth recording how this was found: the Codename One simulator reproduces it exactly and answers in ONE minute what the device answers in fifteen, with real stack traces and the same MCP tooling (its channel is on 8765, not the app's 8766). Four attempts at this bug were spent on device build cycles that a simulator run would have settled immediately.

AnimatedWidget never subscribed to its listenable, so every subclass sampled a value once, painted a correct first frame and then stood still. That is why the settings button never swept from the sliders into the close X: the icon is an AnimatedWidget over the controller driving that very transition. Shrine's backdrop title and Rally's pie chart were frozen the same way. The builder-callback form already listened; only the subclass form went without. AppBar laid out its title and dropped leading and actions on the floor. Every gallery demo page carries its BACK BUTTON as AppBar.leading and its options/info/code/documentation controls as actions, so each page arrived with a heading and no way out. Rewritten as Flutter's NavigationToolbar arrangement, including the back button Flutter implies when a route can pop. The back arrow itself rendered nothing, and a button consumed only a literal Text or Icon child - anything else fell through to toString(). Together those drew the back button as the string "com.codename1.flutter.material.BackButtonIcon@1a2b3c", which the bar clipped to a cryptic "com.c". Buttons now look through wrappers and composed widgets for the glyph they should draw. PopupMenuButton rendered nothing at all when written the usual way (no child, no icon - Flutter falls back to the overflow glyph) and never presented its menu. It is now a real CN1 Button: an InkWell's gesture pane is an ordinary sibling in the flat component list, so an enclosing scroll view's pane sat above it and ate the press, leaving a button that drew correctly and did nothing. Verified in the simulator on the app bar demo, which now shows its back arrow, menu, title, favourite, search and overflow, and whose settings icon animates. 26 new tests; 230 pass.

But it also sat ABOVE any control in that subtree, so a button inside a scrollable or inside a tappable region never saw a press - and Flutter's hit test does the opposite, giving the innermost target priority. The failure is invisible: the control draws correctly, responds to nothing, and looks exactly like a screen that was never finished. It is why the app bar's overflow button did nothing at all even once it was a real CN1 Button - the demo page's scroll pane had a gesture overlay stretched across everything, including the bar. The overlay now looks through its OWN subtree for an interactive component under the touch and hands the press to it, staying CN1's event target so an enclosing scroll still sees the drag. A drag is still treated as a scroll rather than a tap on the control, as CN1 would. With that, the popup menu opens; it is anchored beside its button with the CN1 popup's arrow and dimming stripped, since a Material menu has neither, and its items get Material's 48lp rows. Verified in the simulator: the app bar demo's overflow opens First/Second/Third. 233 tests pass.

Its Dart holds the sort column in a RestorableIntN - nullable, and null until a column is sorted - and passes it as `sortColumnIndex: _sortColumnIndex.value`. The stub declares that parameter `int?`, but the Java setter took a primitive `long`, so the transpiled call unboxed null and threw before the page could build. Every nullable-declared numeric and boolean setter on both data tables had the same shape and would fail the same way the moment its value was null; they are all boxed now. Found by walking all 41 demo routes and reading back what each one reported (tools/sweep.py, added here). 36 were clean. The rest name features that are genuinely not built yet rather than broken: OpenContainer renders nothing (the whole motion demo, 18 instances), CupertinoContextMenu, CupertinoScrollbar, FlutterLogo, and Ink's decoration.

Each was a silent hole: a plausible screen with a piece absent, reported only to a diagnostic channel nobody reads while using the app. The transition family never applied its effect at all - a FadeTransition never faded, a ScaleTransition never scaled, a SlideTransition never moved - so every animated reveal in the app was a cut. They are AnimatedWidgets now, rebuilt on each tick, composing the Opacity and Transform elements that already worked. SlideTransition and FractionalTranslation share a render element that reads the offset at PAINT time, because the fraction is of the child's own size and a per-frame rebuild would relayout a subtree for a change of where it is drawn. OpenContainer rendered an empty box, which took the whole motion demo with it - eighteen containers' worth. It shows the closed state and pushes the opened page as a route; the growth between them is a cut rather than a morph, which is the one part of the container transform we cannot composite. Also: FadeScale/FadeThrough/SharedAxis transitions follow the animations package's own curves; RotatedBox rotates its LAYOUT (an odd quarter turn swaps width and height, which is its whole difference from Transform.rotate); PositionedDirectional resolves start/end against the ambient direction; GridTile stacks its header and footer; Ink paints its decoration; FlutterLogo is drawn from the artwork's polygons; SimpleDialogOption responds to a tap; SliderTheme is a real InheritedWidget, so slider styling stops being discarded; LicensePage renders; CupertinoContextMenu opens on long press; and ClipRect's Clip.none finally does not clip - it was cutting content and merely reporting it. The seven remaining reports are all conditional: platform-capability notices and debug-gated diagnostics, not absent features. The data table now uses Material's metrics - a label column that absorbs the slack instead of an equal share that squeezed the names to two characters, right aligned numerics, sort arrows that re-sort, and a working pager. The popup menu drops CN1's speech-bubble arrow and stops tinting the page behind it, neither of which a Material menu does. 19 new tests; 250 pass.

Dividing the width between them regardless turned "16.0" into "16." above "0" and stood every row two lines high, and pinning the row to Material's 48lp then sliced the taller ones through the middle of their second line. Flutter's answer is to scroll the table, so that is what this does: SingleChildScrollView gained the scrollDirection its stub never declared (the render element already knew how to scroll horizontally), and the table asks for the width its columns actually need. That exposed the other half. The gesture overlay forwards a PRESS to an interactive component inside it, but a horizontal drag over a scroll pane was still the overlay's, and CN1 routes a drag from whoever took the press to the nearest scrollable ANCESTOR - so every horizontal drag went to the page's vertical scroll and the inner pane never moved. A scroll pane now counts as an interactive target and receives the drag, which is the same fix as the button case: the innermost thing wins, as it does in Flutter.

Selector and Consumer looked their model up with providerValueOfType(Object.class) — the NEAREST provided value of any type, which is right only when a single model is in scope. Reply has its localizations and its EmailStore above the same Selector: it took the localizations, and Java erasure meant nothing could tell it otherwise. The lookup was always type-aware (InheritedValueProvider.providedValueFor). The missing piece was the type, so the emitter now writes the Dart type argument out as a class literal at the construction site and the widgets pass that instead. Only for a plain class — a generic or dynamic argument has no class literal and keeps the nearest-wins default, which is no worse than before. Worth noting how differently this presented. On the desktop it was an honest ClassCastException naming both types. On iOS the cast is unchecked, so the wrong object flowed on untouched until an unrelated switch over MailboxPageType matched nothing and threw "No matching switch expression case" — a message that points nowhere near the cause. The same bug, and only one of the two reports is worth reading. Verified in the simulator: /reply renders its mailbox, senders and avatars with no errors reported.

Three defects stacked, all in the same place: MediaQueryData.fromDisplay() called the three-argument constructor, so padding defaulted to zero on every device. Every MediaQuery.of(context).padding read returned nothing to work with - the gallery sizes its settings button as height + padding.top, so that button came out short by exactly the notch. Codename One already knows the answer (Form.getSafeArea, backed by the port's getDisplaySafeArea); the runtime never asked. SafeArea rendered its child unchanged, on the stated theory that "Codename One's Form already keeps content within the safe area". That is not true of a Flutter subtree laid out inside a raw container, so every SafeArea in the app was a no-op. It now resolves to a Padding over the ambient insets, taking only the edges whose flags are set and never less than minimum. And MediaQuery.of ignored its context entirely, always recomputing from the Display, so an in-tree MediaQuery was decorative - a subtree could not be given different metrics, which is what Flutter's removePadding/copyWith idiom is for. It is a real InheritedWidget now. Why no test caught this: an error report cannot see geometry, and the Flutter goldens I diffed against were rendered in a widget test with NO device insets, so the reference shared the defect and the comparison came out quiet. The tests here assert the CONTENT's position, not the root's size - a root under a tight constraint fills the screen whether or not anything was inset, which is precisely the assertion that would have kept passing. 261 tests pass.

Asking for /shrine logged "no route for '/shrine'" and left whatever was already on screen showing, so the sweep — which reads the error inventory — called it clean, and the visual diff compared the gallery's home page against a Shrine reference and reported a number as if it meant something. Three stacked causes: * One route table per PROCESS. A study is a whole MaterialApp of its own, so opening Reply replaced the gallery's table with Reply's, permanently: popping back does not rebuild the outer app. The table now belongs to the app that published it and a push resolves against the nearest app above the pushing context, falling back to the root app's. * The same for the root scope. Reply's MaterialApp claimed the remembered "push from outside the tree inherits from here" position; once Reply was popped that element was unmounted, and re-entering Reply mounted its page with GalleryApp as its only ancestor — above the app's Localizations, where `GalleryLocalizations.of(context)!` is null and AdaptiveNav dies on the null check. Only the outermost app claims the scope now. * A dead route name was a log line. It is a reported failure now, so a screen that never opened can no longer read as a screen that opened cleanly. With the routes reachable, Shrine and Crane failed in their library's static initialiser. Dart initialises top-level variables lazily, on first read, so shrine/theme.dart may write final ThemeData shrineTheme = _buildShrineTheme(); // reads the scheme final ColorScheme _shrineColorScheme = ColorScheme(...); Emitted as Java fields in textual order the first one reads null. The emitter now gives any top-level variable whose initialiser is not a bare literal a lazy accessor pair, named get$x/set$x so reads and writes route through the existing accessor handling. A behavioural case pins it, run from the same file on the Dart SDK. Both studies then threw on `base.iconTheme.copyWith(...)`: Flutter's ThemeData() fills every slot in, ours left iconTheme null. It defaults now, as sliderTheme and navigationRailTheme already did. Also fixes the reference corpus the visual diff is measured against: the four deferred studies were rendering as black frames (a deferred load never resolves under flutter test's fake clock), '/demo/null' was never a route, and screens that animate forever failed on pumpAndSettle instead of producing a golden.

Both carried a comment promising the real behaviour later. Crane is built on the first one: its back layer is an IndexedStack over the Fly / Sleep / Eat forms, so the study opened with all three printed on top of each other — "Travelers" over "Diners", "Choose Origin" over "Select Location". Nothing threw, so the sweep called the screen clean. The unselected children stay mounted, which is the reason to reach for an IndexedStack in the first place; they are laid out against a zero-size constraint, which is how a subtree draws nothing here without being torn down. Visibility falls back to its `replacement`, defaulting to an empty box as Flutter does.

The options (tune) button was absent from all 41 demos. A button consumes its icon rather than mounting it, so it walks the widget to find the glyph — and the gallery hands it `IconButton(icon: FeatureDiscovery(child: Icon(...)))`, whose state builds a LayoutBuilder. The walk knew about wrappers, stateless and stateful widgets but not that, so it gave up and drew nothing. The walk now goes through WidgetPreview, which takes one step of composition whatever the shape is — including building a LayoutBuilder's builder — and attaches a throwaway state to its widget first, since a State's build reads `widget.x` on its first line. Nothing read AppBarTheme at all. Every bar fell back to the M3 default of colorScheme.surface, so the demos lost the Material purple bar the gallery themes them with (`AppBarTheme(color: colorScheme.primary)`) and came up the same grey as the chrome around them. Resolution is Flutter's order now — AppBar.backgroundColor, then AppBarTheme, then the M3 default — and AppBarTheme.color is read as the alias for backgroundColor that it is. The bar's foreground follows the same path; AppBar.foregroundColor and AppBar.iconTheme were being dropped on the floor by no-op setters.

Label handles that by locking its ICON while it is on screen, which is why nothing had to think about it before: components that show a picture show it as an icon. FittedImage does not. It paints its source directly under a BoxFit rule rather than holding a scaled copy as an icon -- that is what keeps one bitmap in memory instead of two -- and in doing so it stepped outside the locking Label does for free. A picture drawn every frame and collectable between them is a picture decoded every frame. It now takes the lock on the same boundary Label uses: on screen when the component initialises, off again when it deinitialises, and following the source when the source is replaced. The bookkeeping lives in ImageLock rather than inline, because that is where the two failures are -- a lock left on a replaced picture is never released, and a second lock on an already-locked picture is never balanced -- and because it can then be tested at all: constructing any Image needs an initialised Display, which the headless suite does not have. Whether the component is on screen is tracked rather than read back from isInitialized(), since the framework clears that flag before it calls deinitialize() and a lock that depends on the order of those two is a lock that leaks the day the order changes. Measured on the merged tree, best of nine interleaved launches: physical footprint 121MB against 86MB, where the same comparison was 219MB against 106MB this morning. The benchmark dataset and STATUS.md are updated, and iOS is recorded as deliberately unmeasured -- the Flutter iOS build is always debug, so that comparison would flatter Codename One and mean nothing.

Uploading a picture allocated a full-size scratch buffer, rasterised into it, and then copied the whole thing AGAIN through replaceRegion. On a unified-memory device the texture can be a view onto an MTLBuffer, so CoreGraphics is pointed straight at the memory the GPU will sample and the picture is rasterised once, into its final home. Discrete GPUs keep the copying path: a linear shared-storage texture there lives in system memory and every sample crosses the bus, which trades a one-off copy for a permanent sampling cost. This matters past the copy itself -- libmalloc on this platform never returns the pages a peak touched, so a transient full-size buffer per image at start-up is charged for the life of the process. That change needed a CGContextFlush, and finding out why is the useful part. A self-check comparing the new reader against CoreGraphics pixel by pixel (CN1_VERIFY_RGB) reported 4344 of 215040 pixels reading back as ZERO on two runs out of twenty. Releasing a bitmap context is not documented to flush it; the old shape got away without one because replaceRegion copied the bytes out through CoreGraphics' own accounting, whereas the texture here IS that memory. Without the flush the upload produces occasional torn images -- the shape of bug that survives testing and shows up in the field. Reading pixels back from a mutable image allocated a scratch texture the size of the whole image, blitted the whole image into it, and malloc'd the whole image again, in order to hand back a sub-rect: a 100x100 getRGB on a full-screen mutable moved 12MB three times to deliver 40KB. It now stages only the rect, when no scaling is in play. getRGB on an ordinary image rasterised through CGContextDrawImage on every call, and the decoded copy CoreGraphics caches to do it stays resident next to the Metal texture uploaded from the same picture -- the image is in memory twice. Where the texture is CPU-addressable the bytes are taken from it directly, with the row order and channel order the sampler's layout implies, and the check above is what says that is right. Finally, the #5349 revalidation re-rasterised every image after every foreground or memory warning. Only PRIVATE storage is at risk of iOS discarding contents; a shared-storage texture is ordinary memory and revalidating it buys nothing.

A pixel-level check of the resulting texture against CoreGraphics found regions reading back as ZERO, unwritten: 1554 and 45856 pixels of a 560x384 image, on two reads out of eighteen. CGContextFlush before creating the texture did not fix it, it only made the clean runs more common -- three consecutive clean runs preceded the two that failed, which is exactly why one clean run proves nothing here. The cause is not pinned down (CoreGraphics deferring into a linear destination, or getMTLTexture racing another thread), and it does not need to be: the failure is intermittent, silent, and corrupts what is DRAWN as well as what is read back. An occasional torn image in a shipping port is not worth a memory optimisation that could not even be measured on this machine. replaceRegion copies the bytes out through CoreGraphics' own accounting and has never shown a hole. The finding is written into the comment where the next person will look. The getRGB texture reader and the shared-storage revalidation skip go with it -- both only ever applied to a shared-storage texture, which no longer exists. Kept, because both were verified: Image.createImage(int[], w, h) now premultiplies in ONE PASS. It used to wrap the caller's array in a CGImage, malloc and zero a second full-size buffer, draw the first image into the second through the whole CoreGraphics pixel pipeline, and make a third CGImage out of the result -- to multiply three bytes by a fourth. This is on the start-up path: it is how the runtime rounds the corners of every card image. Premultiply is rounded rather than truncated, or every semi-transparent pixel drifts a level darker. CN1_VERIFY_ARGB reproduces the old conversion and compares pixel by pixel: 36, 24 and 36 images across three runs, zero differing pixels. Mutable-image readback stages only the rect that was asked for. It used to allocate a scratch texture the size of the whole image, blit the whole image into it and malloc the whole image again, in order to return a sub-rect: a 100x100 getRGB on a full-screen mutable moved 12MB three times to deliver 40KB.

That made each on-screen picture resident TWICE -- CoreGraphics' decoded raster on the CPU plus the texture on the GPU -- which is the whole of this port's "CG raster data" against a competing toolchain's zero. It was never needed for an EncodedImage. That class already holds the encoded bytes and already re-decodes on demand; it is a complete recovery path, and the UIImage was a second one duplicating it. So EncodedImage now decodes through createImageNoBackingCopy, and the iOS peer releases its UIImage the moment the texture exists. Recovery is a static generation counter: applicationDidEnterBackground bumps it, and each instance compares its own generation the next time it is asked for pixels, dropping the stale decode and decoding again from the bytes it kept. A counter, deliberately, not a registry and not a sweep. Nothing is walked and nothing is touched at suspend; an image that is never used again is never looked at. A locked image keeps its stale decode until it is next asked for, and then discards it unused -- so locking cannot pin a decode the platform invalidated, and the lock protocol is not disturbed. Width and height are NOT reset, because they are a property of the encoded bytes, which have not changed; resetting them would make every layout that measured the image wrong until it re-decoded. The peer also stops revalidating itself on the texture-validate generation when it has no backing copy: that recovery is both impossible (nothing to re-decode from) and unnecessary (its Java owner rebuilds the whole image, peer included). Default createImageNoBackingCopy is plain createImage, so every port that never kept such a copy is untouched. core-unittests: 5214 pass, including four that pin the generation -- a decode is cached when nothing invalidates it, invalidation forces a re-decode, it reaches locked images without breaking the lock, and it leaves dimensions alone.

Gated on CN1_STARTUP_PHASES, so a shipping build pays one cached getenv. Probes at main (initConstantPool), at UIApplicationMain, and at didFinishLaunching. The reason for it: two trivial C programs, identical source, one native macOS and one Mac Catalyst, timed launch to main best-of-15 -- AppKit 6.6ms against Catalyst 19.4ms, with Catalyst loading 1565 dylibs to AppKit's 738. So Catalyst costs about 13ms and that is now measured rather than assumed. It also kills a hypothesis: adding all 26 of the frameworks this port links took that same trivial Catalyst binary from 19.4ms to 20.8ms. The framework list is a real difference against the competitor's and an irrelevant one; Catalyst already pulls everything. And it reframes the rest. Codename One reaches main at the same ~20ms any Catalyst app does, so the ~97ms this branch had been calling pre-main overhead is mostly AFTER main -- VM init, UIKit bring-up, Display.init -- about 77ms of our own initialisation, three times the size of the gap being chased, never decomposed until now.

This is the number vsync cadence cannot give you: a renderer presenting at a steady 60fps looks identical whether it used 2ms or 15ms of the 16.67ms budget, and the difference is exactly what decides whether there is room to repaint more. The question it exists to answer: the offscreen screenTexture costs a fixed full-screen texture -- 12MB, about 43% of the remaining memory gap against the competitor -- to allow partial repaint. CN1_REPAINT_RATIO, with the application properly foregrounded, says the application repaints 64-86% of the screen per frame, so partial repaint is saving only 15-35% of the pixel work. On the face of it that is a bad trade, but removing the texture makes every frame a full repaint and nobody should do that without knowing the GPU has the headroom. Two traps this work uncovered, both worth knowing before trusting any rendering measurement on this platform: Launching the binary from a shell leaves it reporting as BACKGROUNDED, and drawFrame returns early there, so the renderer never runs. Use `open -a .app`. bench_fps keeps reporting ~60fps either way because it reads the Java-side EDT counter, not GPU frames -- a terminal-launched fps figure is EDT cadence, not rendering throughput. And both applications use meaningfully more memory when active: Codename One 128.8MB against 148.4MB, the competitor 100.0 against 114.6. The comparison survives, since both sides are measured identically and move similarly, but the absolute figures describe an idle unfocused application rather than one a user is looking at.

The two halves are alternative implementations of the same conversion, so the fix is to take one of them whole. This takes the branch's, which the merge otherwise loses: Codename One hands over straight (un-premultiplied) ARGB and CoreGraphics wants it premultiplied, and master's way of getting there wraps the caller's array in a CGImage, mallocs a second full-size buffer, memsets it, wraps THAT in a bitmap context, draws image one into image two through the whole CoreGraphics pixel pipeline, and makes a third CGImage of the result -- to multiply three bytes by a fourth. Image.createImage(int[], w, h) is on the start-up path (it is how the runtime rounds the corners of every card image), so that ran once per picture during the first frame. The single pass also has to round rather than truncate: CoreGraphics rounds, and a truncating premultiply drifts one level darker on every semi-transparent pixel. Channel order and premultiply rounding are invisible in a stack trace and show up as an image that is subtly dark or blue, so the conversion carries its own check: CN1_VERIFY_ARGB reruns the old CoreGraphics path and reports any pixel that differs. Verified against a 256x256 image covering every alpha 0-255 against a full colour sweep -- all 65,536 pixels identical, "CN1_VERIFY_ARGB: 256x256 matches". cn1ArgbImageFreeData comes back with it: the provider owns the premultiplied buffer and frees it through that callback, and it must be a C function pointer, so it lives at file scope.

Rendering: the CAMetalLayer is replaced by a plain CALayer fed from one IOSurface-backed MTLTexture. The layer's drawable pool has a minimum of two buffers that a framework which owns its own framebuffer never needs, and handing the surface over from addCompletedHandler instead of waitUntilCompleted takes a 16ms stall off the first frame. Window: the build is queued on the main queue before [NSApp run] so it overlaps VM boot rather than following it, the primary display scale is published before the window exists so the first layout does not have to wait for one, and macMonitorForMainWindow no longer builds a window just to answer a question about monitors. displayWidth/displayHeight return a default size when no window exists yet; a size change is delivered later, and the extra layout that costs is cheaper than the stall it removes (reverting it cost 15ms). Fonts: registering all 33 bundled font files up front is replaced by registering the single file a font resolution actually names, with the whole-bundle scan kept as the fallback for a name that will not resolve. Instrumentation: cn1StartupPhase() markers behind CN1_STARTUP_PHASES (one cached getenv) report where cold start goes, including the VM's constant pool. They are what showed that the constant pool costs 1ms, that the window costs 41.8ms of which 27.4ms is inside AppKit's own initWithContentRect:, and that an earlier 46.7ms "present path" was machine load rather than a real cost.

An allocation census counted 6,443 of those callbacks on one screen, the largest anonymous-class count in the runtime. One collector now serves the whole walk; it holds no per-node state, so reusing it down the recursion is safe. ImageRenderElement read a PNG/JPEG/GIF header for its dimensions instead of decoding the image to answer getWidth(), so an image that is only measured is never decoded. That is 38% off simulator start-up (402ms -> 262ms in invokeMain) and near zero on a native build, where decoding was already cheap. RenderElement decides per UIID, keyed on the theme generation, whether a component needs its Codename One styling neutralised, instead of asking per component; FlutterUI emits zero margins for the Flutter UIIDs up front so four of eleven stop needing the treatment at all.

This runtime read that default as `contain` and BoxFit.scaleDown itself fell through to the `contain` arm, so every under-sized picture was blown up to fill its box with no way to ask for the real behaviour. Image.asset also accepted cacheWidth and cacheHeight and dropped them on the floor. They bound the decoded bitmap, so they bound everything downstream: the intrinsic size layout constrains and the size the picture is painted at. They apply in decoded pixels, before the density variant is rescaled to the screen, and they never enlarge -- ResizeImage passes allowUpscaling false. dart:ui decodes to exactly both dimensions when both are given, so the aspect ratio survives only while one of them is left open. Layout now constrains the way RenderImage does, preserving the aspect ratio rather than clamping each axis on its own; clamping independently gave a box with the constraint's width and the picture's own height, which sat the artwork in vertical slack and pushed everything below it down by half the difference. Measured against the reference gallery, worst-first over 47 routes: the mean share of the screen that is wrong falls from 4.64% to 4.45%. The lead photo route goes 19.11% -> 9.50%, and the reply study's attachment thumbnails, which were drawn at 432px against the reference's 200px, now match it exactly.

That question arrives as a real layout call -- not a dry one, so the existing guard did not catch it -- with the width unbounded, and the answer to it is discarded a moment later when the parent comes back with the box it actually chose. A Flutter builder is allowed to LATCH. The 2D-transformations demo centres its board against the first constraints.maxWidth it is ever shown and keeps that matrix for the life of the route, so the speculative call decided the screen: it was handed an infinite viewport, computed a centring offset from it, and the board drew in the corner with its left edge cut off. Flutter never reaches the builder that way -- LayoutBuilder refuses intrinsic queries outright rather than running the callback against a box it will not be painted at. So sit out one unbounded pass. If the next one is unbounded too then this really is an unbounded layout -- a viewport's child -- and the builder runs against it as Flutter would. Sitting out has to drop this element's cached layout result or the pass that follows is served the placeholder instead of running the builder, which turns "sit out once" into "never build" for exactly those viewport children; the dry path already does the same thing for the same reason. Worst-first over 47 routes, the mean share of the screen that is wrong falls from 4.45% to 4.18%. The transformations demo, previously the worst route, goes 23.38% -> 14.72%, the reply study 19.98% -> 15.65%, and no route regresses.

AppBarTheme.titleTextStyle ?? textTheme.titleLarge`. The last link was missing, so a bar whose theme names no title style -- which is most of them -- fell through to whatever size a bare Text picks. That is about 16 logical pixels against titleLarge's 22, and every title in the gallery rendered at roughly seven tenths of its size: the typography demo's title measured 43 device pixels tall where the reference is 56, and 241 wide where the reference is 335. Measured against the reference it now matches exactly -- 56 tall, and 323 wide against 335. The aggregate diff does not move: a title drawn at its real size covers more of the screen in glyph edges, and our rasteriser and the reference's disagree along every one of them, so nine routes drift by three to six hundredths of a percent while the typography demo, whose title this most obviously fixes, does not change at all. The absolute measurement is the check that matters here, not the aggregate.

Reply's compose button is centreDocked: it belongs centred, with its centre ON the bottom bar's top edge, which is what lets a notched bar cut a hole for it. Its centre now lands at 562 device pixels, which is where the reference puts it. The FAB was also mounted third of six, and components attach in mount order, which is this host's paint order -- so the bottom bar and the persistent footer were painted over it. Flutter's _ScaffoldSlot orders the FAB after both. A docked FAB lost its whole bottom half that way. Its shape came from whatever the Codename One theme in force carried for the UIID, which for this runtime's theme is nothing, so a background colour filled a hard-cornered block. A Material 3 FAB is a rounded square of 16 logical pixels, not the disc Material 2 used. And its colours were never resolved at all: Material 3 defaults them to primaryContainer over onPrimaryContainer. The bottom-app-bar demo drew a pale lavender button with a purple glyph where the reference is purple with a white one -- the two roles exactly inverted. Separately, Material understood RoundedRectangleBorder and nothing else, so a CircleBorder fell through to a corner radius of zero. Reply's compose button is not a FloatingActionButton on mobile at all: it is an OpenContainer whose closedShape is a CircleBorder, and it drew as an orange square. A CircleBorder is the circle inscribed in the box, so as a rounded rectangle it is a radius of half the shorter side; the button now measures 168x168 filling 0.743 of its box against the reference's 167x168 at 0.745. Worst-first over 47 routes the mean falls from 4.17% to 4.01%. Every study improves by about one and a third points -- their Back buttons are extended FABs that were wearing the wrong colour -- and nav_rail moves the other way by 0.13 because its FAB is now correctly purple while the navigation rail it belongs to is still missing entirely.

Codename One's text field has no icon slot, so the icon and the editor now share a container and the decoration's surface moves onto it, because in Flutter the fill and the border enclose the icon too. Every read and write of the editor goes through a held reference rather than through component(), which is no longer the editor when there is an icon. Two units traps on the way in. FontImage sizes glyphs in MILLIMETRES, so passing 24 logical pixels asked for a 24mm glyph and drew a person icon taller than the row it sat in; Dp.mm is the conversion, the same one IconRenderElement uses. And the glyph's colour falls back to the ambient IconTheme when the Icon names none, without which it is painted in the default ink -- black, on Crane's purple rows. Measured against the reference the icon now lands within a few pixels of it. TextField.style was also stored and never read, so a field rendered at whatever size Codename One's default font happens to be. Crane moves 17.22% -> 17.33%. The icons are right and were absent before; what the extra tenth measures is the hint beside them, which is still half again too tall -- 56 device pixels of ink against the reference's 36 -- so drawing the icon correctly shifts a still-wrong placeholder into a new wrong position. Applying Flutter's hint chain on top of this was tried and reverted: it changed the colour and not the size, because Codename One's hint label does not take the derived font, and that measured worse still at 17.80%. The size is the thing to fix first and it is not a styling problem.

That theme was held opaquely on ThemeData and never read, so a study that names its field styling once on the theme rather than on each field got none of it. Rally is the case that shows what it costs. Its login fields carry nothing but a labelText; the dark fill they sit in is named on the theme. Without the fallback they rendered as two white blocks on a dark page -- the largest wrong area on the route by a wide margin. The route goes from 11.30% of the screen wrong to 6.26%, and the mean over 47 routes from 4.01% to 3.90%. Shrine, which names content padding the same way, moves with it. `filled` is a primitive on both sides, so "unset" and "false" cannot be told apart; a theme that asks for a fill therefore wins over a decoration that simply did not mention one, which is the case the studies exercise. The borders stay opaque: most of them are shapes this port cannot draw, and none of the gallery's themes depend on one to be legible.

Codename One clips every component to its bounds -- Component's internalPaintImpl does it unconditionally -- and those bounds are read in the coordinates the graphics is currently painting in.

The board was clipped to the surface's own width first and then shifted, so the rightmost 64 logical pixels of the viewport were bare background: a dark strip down the right-hand side exactly as wide as the shift. Hexagons stopped at device x 884 where the reference carries them to 1072. The shift is recoverable rather than guessed. A graphics being painted through has accumulated exactly its ancestors' offsets, so absent a transform its translation plus the component's parent-relative position is its absolute position; whatever that identity is out by is the transform.

Unbounded on its own is not the signal. A viewport's child is legitimately unbounded along the scroll axis and Flutter hands it infinity too: a mail card in a vertical list gets a TIGHT width of 367 and a height of zero to infinity, and its builder is meant to run against exactly that. Sitting it out returned a zero height, which the list then kept, so every card in the study collapsed and the route rendered as bare background. What separates a real pass from a measurement is the CROSS axis. A viewport gives its child a tight cross-axis extent; "how big would you like to be" is loose in both directions, which is what the transformations demo was answering when it latched an infinite viewport. The diff score did not catch this. It went DOWN, 18.96% wrong to 15.65%, because blank background differs from the reference less than mis-rendered cards do -- the metric rewards deleting content. It is caught now by a test that pins the viewport-child case directly, and that test fails against the old rule. Restoring the cards puts the route back at its real 20.22% and the mean over 47 routes at 3.93%, up from a 3.80% that was partly measuring an empty screen.

Its SIZE came from the component's preferred size, which is the glyph plus whatever padding the theme in force carries. With no theme entry for the UIID that is 83 device pixels against the reference's 168 -- less than half. Material fixes it: a regular button is a 56 logical pixel square, and an extended one fixes its height too and lets only the width follow its label. That height is 56 in Material 3, not the 48 Material 2 used, which is what the reference draws. It also could not use Codename One's own FloatingActionButton at all. That class re-installs its own circular border from styleChanged() every time the background colour is set, so the Material 3 shape put on it was replaced the moment the colour followed and the button painted 96 device pixels of surface inside its 168 pixel box. The extended form already had to be a plain Button wearing the same UIID, for its own reason; both forms are now. And it sat too LOW. Flutter measures the button from the bottom of the CONTENT, which excludes the display's own bottom padding, so measuring from the bottom of the scaffold put it over the home indicator instead of above it -- 102 device pixels out on the starter study. The starter study's button now lands at exactly 168x168 at (909, 2118), which is where the reference puts it. Eight routes improve, the motion demo by 1.15 points and the starter study by 0.98, and the mean over 47 routes goes from 3.84% to 3.78%. The navigation-rail demo moves 0.34 the other way: its button is now correctly sized and placed in a screen whose rail is still missing entirely, so there is more of it to be wrong.

Everything that makes a rail a rail -- the destinations, their icons and labels, the selection, the surface it all sits on -- was captured and dropped, so the navigation-rail demo drew its create button floating in the middle of an otherwise empty page. The rail is now a fixed-width column: the leading widget between Flutter's vertical spacers, then a slot per destination, then the trailing widget. A destination shows its selectedIcon when it is the selected one, and its label when labelType asks for it -- all of them, only the selected one, or none. Two defaults were also wrong by being absent. useIndicator is a primitive that read false, so the selected destination had no pill behind its icon; Material 3 draws one, tinted with secondaryContainer. And a rail that names no backgroundColor falls back to colorScheme.surface, without which the demo's rail was invisible -- white destinations on a white page, which is why the whole control could be missing and the diff barely moved. Separately, the FAB's glyph was rasterised BEFORE its style was applied, so the theme's default ink was burned into the image and the button wore a dark plus sign on a purple surface where the reference has a white one. The glyph now follows the style, in both the create and update paths. The demo goes from 2.68% of the screen wrong to 1.68%, the starter study from 2.25% to 1.95%, and six other routes follow the glyph fix. The mean over 47 routes goes from 3.78% to 3.73%, with nothing regressing.

Every file this branch's parity work touched was in that state, which would have turned the gate red on a change that has nothing to do with licensing. This covers only the twenty-six files that work touched. The condition is branch-wide and much larger -- 763 of flutter-runtime's 772 sources and all 38 of dart-transpiler's carry no header -- and sweeping those is a separate change that would swamp anything it travelled with.

Material 3 makes it 80, which is what the reference draws -- exactly 80 in the bottom-app-bar demo, measured at the pixel. Where the reply study's bar looks 114 tall it is that same 80 over 34 of the scaffold's own dark background showing through the display's bottom padding; the padding is not the bar's to carry, and giving it to the bar made every embedded bar 34 logical pixels too tall. The floating action button was also clearing the bottom twice. It measures from the bottom of the CONTENT, and a bottom bar IS what holds the content off the edge, so adding the display's padding on top of the bar's height double-counted it. On the reply study that lifted the docked button clear of its own bar and into the mail list, where a card painted over it and it disappeared entirely -- a button that had been visible a commit earlier.

The reason was a bad probe: it derived from whatever font the theme had left on the component, and a SYSTEM font does not derive -- Font.derive returns it unchanged -- so every size handed to a placeholder was dropped on the floor. TextRenderElement does not hit this because it resolves the style's named family to a bundled TrueType face first, and those do derive. So the field does that too, and with the size actually landing, Flutter's chain is right after all: titleMedium merged with the field's own style, recoloured with the theme's hintColor, then merged with an explicit hintStyle. The recolour matters on its own -- a placeholder that keeps the INPUT's colour is white on every row of Crane's search form, where the input colour is white. Crane's placeholder now measures 36 device pixels of ink against the reference's 36. It was 56. Crane 17.15% -> 16.75%, shrine 3.02% -> 2.74%, and the mean over 47 routes 3.65% -> 3.63%.

The reply study's bar reads as one 114 logical pixel block of colour with its Inbox row in the top 56; laying Material's 80 flush instead put a white strip where the reference is dark and pushed the whole body 34 lower -- the single largest wrong band on the route, 280 device pixels tall and 97% wrong. So the strip is laid out that much taller, stays flush, and holds its content at the top. The body stops short of the band with it. Only when the scaffold IS the display. That is the one thing separating a full-screen study from a demo shown inside a card, and it is why keying on root mode failed earlier: both are embedded in the gallery's page. The size says it, and by the time the strip is positioned the size is known -- which is why this belongs in layout and not in the widget, where an earlier attempt had to guess before anything had been measured. Measured against the reference the band is now 114.0 logical pixels against 114.0, from 2094 to the bottom edge in both.

The reference set covers 47 demo and study routes and the home screen is not one of them, so no golden existed, the sweep never opened it, and the first thing anyone sees was the one screen nobody was checking. Measured against a golden generated for it, it came in at 20.10% wrong -- worse than any route in the set. Almost all of it was one thing. Flutter's BoxScrollView does not leave a null padding null: it takes the ambient MediaQuery padding along its OWN axis, applies it, and removes it for everything inside so it is not counted twice. That is how a full-screen list keeps its first item out from under the display cutout without anyone writing a SafeArea, and the home list relies on it entirely -- it has no padding, no SafeArea and no app bar. Without it the title sat 133 device pixels too high, under the island, and every following thing with it. It now lands at rows 215..271 against the reference's 216..272. The Scaffold's half of the same rule was also missing: the body loses its top padding when an app bar stands in for it, and its BOTTOM padding when a bottom bar or a footer does. Leaving the bottom in place under a bottom bar counts it twice. The home screen goes 20.10% -> 3.10%. Three routes move the other way by 1.9 between them, and the 48-route mean lands at 3.59. The home golden is generated with isTestMode OFF, unlike the demo routes. There it does not only suppress the coach mark: the home page reads it as `initiallyExpanded: ... || isTestMode`, so a reference captured with it on shows the Material category already open, which is not what the app does when someone launches it.

Only the iOS port implements isRoundedImageDrawSupported, so a rounded picture is a rounded COPY of the bitmap on the desktop and a drawImageRounded call on iOS. That call rounds what is DRAWN. A cover fit paints a rectangle larger than the component, so its rounded corners land outside the clip and what shows is four hard ones. Measured on the simulator: the reference's corner walks in 188, 176, 169, 163, 160, 159 over the first 35 rows and ours sat flat at 159 the whole way. An overflowing fit therefore goes through the copy, which scales to the box first and rounds that. Nothing on the desktop moves -- it was already taking that path for every rounded image -- so this is verified on the device, not in the sweep.

That is true of a conforming PNG and false of the ones an iOS app ships: Xcode rewrites every bundled PNG into Apple's CgBI form, which prepends a four-byte CgBI chunk. We were reading that chunk's payload as the width and its CRC as the height, so every bundled picture on device was measured to a garbage aspect -- the gallery's category icons drew 139x84 where the reference draws 139x154. Nothing on the desktop can see this. The desktop port reads the same asset straight from the jar, where it is still an ordinary PNG, so the sweep was pixel-exact on the very screens that were visibly wrong on the device. Walk the chunk list to IHDR instead. Anything without one -- a truncated file, or a container we do not know -- answers {-1, -1} and falls back to the decoding path, which is slower but never wrong.

The two agree until a matrix is not a pure translation. Container.paint's g.translate(getX(), getY()) then moves the origin by getX()/scale user units rather than by getX(), so the clip the cull tests against drifts further with every level of nesting, and a child that is plainly on screen gets dropped. The gallery's carousel is where this shows: it scales the card on either side of the current page, and the 1019px translate out to the next card became 1171 user units, carrying the clip clear of the card's own bounds. The card was not clipped, misplaced or scaled to nothing -- it was never painted at all, which is why the next card never peeked in the way the reference's does. Measured with the existing cn1.flutter.noTransform A/B: 0 pixels painted in the peek strip with the transform on, 58250 with it off. So render the subtree into an offscreen layer and transform the RESULT. Everything downstream of the layer then paints through an untransformed Graphics, in the device pixels Codename One expects, and a pure scale needs no matrix support at all -- it is one drawImage into a destination rectangle, which also fixes the pivot, which was being given in absolute screen coordinates rather than in the space the Graphics was actually in. This is Flutter's own model, where Transform is a layer rather than a paint mode. RotatedBox had the identical defect and gets the identical fix. Its layer takes the child's box rather than the pane's, because its performLayout reports the child's footprint with the axes swapped -- a pane-sized layer would cut the child in half before it was ever turned. Only a desktop width reaches a non-zero quarterTurns in the gallery, so the sweep cannot see this one. The buffer is kept and cleared between frames rather than reallocated: a carousel drag scales a card on every frame, and a fresh full-size ARGB image per frame is exactly the allocation rate that drives a collection mid-drag. Sweep: 48 routes, no route regressed, / 3.10% -> 2.86%. The metric moves little because the peek strip is 2.4% of the screen; the defect is not 2.4% of the screen to look at.

The gallery's settings button is exactly that shape, BorderRadiusDirectional.only(bottomStart: 10): it rendered as a plain white block against a reference that has a rounded bottom-left corner. BorderRadiusDirectional was not recognised at all, so even a uniform directional radius came out as zero. The clip already carried a radius per corner -- clipGeometry has taken four since it was written, to square off a corner the viewport cut through -- so this is only a matter of resolving the four and passing them down instead of collapsing them on the way in. clipRadiusPx() answers with one radius, for descendants that round their own bitmap because a clip is not reliable on every port. It has no honest answer for a non-uniform surface, so it returns 0 there and the caller falls back to the clip, which carries all four. Directional radii resolve left-to-right, as AlignmentDirectional and EdgeInsetsDirectional already do here. Sweep: 48 routes, no regression.

Anything animated by one of them did not move: it sat at its start value for half the duration and then appeared, already finished. The gallery's settings panel is a RelativeRectTween. It begins a full screen-height above the viewport and slides down over 80ms, so tapping the settings button produced a menu that popped into place fully formed rather than one that slid in -- while the settings ICON, which is driven by a separate controller through a painter, animated normally. That mismatch is what makes it read as broken rather than fast. Each value type gains the interpolation, next to its storage: RelativeRect.lerp, EdgeInsets.lerp (which keeps two directional insets directional, so an animation between them does not become left-to-right at the first frame), Matrix4.lerp. BorderRadius.lerp already existed and simply was not being called. The base class still steps for a type nothing knows how to interpolate. That is the deliberate fallback and the tests pin it, so it cannot start returning nulls instead. Sweep: 48 routes, no change -- these are animations, and the sweep photographs screens at rest.

The first screen is BUILT BEFORE IT IS SHOWN -- runApp mounts the tree into a new Form and shows it afterwards -- so nothing was current throughout that build and every inset came back zero. On the launch screen of the gallery that meant the home page's title was laid out under the status bar and its ListView took no top inset: on an iPhone 17 Pro the title sat at y=69 where it belongs at y=255, running into the clock and the Dynamic Island. Any route pushed afterwards was correct, because by then a Form is current -- which is also why every measurement taken after opening a route showed the right geometry and this survived. The context knows which Form it is in, so ask that instead of asking what happens to be on screen. Verified on the device: a fresh launch now puts the title at y=255 and the SafeArea band at y=186, matching the reference frame for frame. Not unit tested: the path needs a live Display and a real Form, neither of which exists headlessly, and a test that faked them would be asserting against its own fake. Sweep: 48 routes, unchanged. The home route stopped REPORTING, which is a harness bug the fix exposed -- parity.py proved a route opened by requiring the screen to change, and home is the screen every route is pushed from, so not opening leaves exactly the right picture up. It only ever measured because the pushed home form had the correct insets and the launch form did not. Fixed in benchcn1 by detouring through another route first.

On iOS it is simply ignored: isShapeClipSupported() answers true, the clip is installed, and the ramp still fills the path's bounding BOX. The gallery's settings icon is two stadium-shaped sticks painted that way, and on the device they came out as square blocks. On the desktop, where the clip is honoured, they were correct -- which is why no sweep ever saw it. Probed on the device: shapes=true shapeClip=true pathBoundsIsRect=false, and the fill is still a rectangle; forcing the solid-shape branch at runtime drew a perfect stadium, so fillShape honours the path and only the gradient does not. So stop asking a shape clip to do it. A rectangular path still goes straight to the port's ramp, which is exact. Anything else fills the SHAPE once per band of the ramp with a RECTANGULAR clip confining each fill to its band -- a rect clip and fillShape are honoured everywhere. The shape is then right on every port and the ramp is quantised rather than absent, which is the correct trade: the old fallback for a port without shape clipping painted the shape in one flat midpoint colour, losing the ramp entirely. The band colour comes from the whole ramp rather than its ends, so a gradient with three or more stops no longer loses everything between the first and the last. Sweep: 48 routes, no change on the desktop, where the shape clip already worked.

Nothing here is third-party -- these are all files this branch wrote -- so they take the standard Codename One GPLv2 + Classpath Exception header like the rest of the tree. Ten of the 828 are excluded instead. maven/dart-transpiler's golden fixtures are its EXPECTED OUTPUT, compared byte for byte against what a transpile emits; a header there is not a licence statement about the fixture, it is an assertion that the transpiler emits one, and it does not -- the files it emits are generated into a build directory and are nobody's source. Adding headers to them broke the comparison they exist to make, which is how they were found. flutter-runtime, dart-runtime and dart-transpiler all build and their tests pass with the headers in place (357, 20 and 47).

      The counters — per-class build time, per-class layout self time, component + * creation cost, glyph rasterisation cost — are what turned "the app takes + * 250ms to start" into a list of things to fix. But they are not free: layout + * attribution alone costs two {@code nanoTime} reads, a + * {@code getClass().getSimpleName()} (which allocates a String) and a map + * lookup on EVERY box laid out, and a screen lays out a few thousand boxes per + * frame.

It advanced by charWidth, which returns an INT, so every glyph's advance was rounded up to a whole pixel while the measurement used stringWidth of the whole run. Two consequences, both systematic: * the drawn run is wider than the box it was given, so the last glyph is cut off -- on iOS that clipped the final letter of Reply's sender lines ("15 minutes ag"), and * every tracked string is wide by roughly the rounding error per character. Measured on the device against the reference: the same sentence drew 607px where the reference draws 589. 3.1%, about 0.6px per character. Text that is systematically wide ellipsises strings that fit and clips the ones that do not. stringWidth measures the whole run in one go and does not carry that error, so keep measuring with it and let the per-glyph widths decide only the PROPORTIONS: scale each advance by stringWidth / sum(charWidth). The run then ends exactly where spacedWidth said it would, on every port. Note this is NOT the same as measuring each glyph with stringWidth: a standalone space measures ~0 there, which is why the paint path uses charWidth in the first place. As a proportion a space is right; as an absolute width it is not. Device: the same sentence now draws 591px against the reference's 589, down from 607. Sweep: 48 routes, mean unchanged.

Probed on the device: set an oval clip and fill the box, and a green SQUARE appears -- with or without the clipRect Codename One narrows to each child, so it is not the intersection losing the shape either. That means every shape clip in the runtime has been inert on iOS: ClipOval, ClipRRect and Material's own. Everything that looks correctly shaped there today is shaped by something else -- fillShape, which IS honoured, or drawImageRounded, which is why a carousel card has round corners. Reply's avatars are ClipOval around a photograph. They drew as squares on the device and as perfect circles on the desktop, whose clip works, so the sweep could not see it. This is the same class of defect as the gradient fill fixed a few commits ago; that one was fixed where it was found rather than where it lives, which is the mistake this corrects. So render the subtree into a layer and hand the LAYER to drawImageRounded, which the port implements natively, whenever the port offers it. Ports whose clip works keep using the clip: it is cheaper and exact for any shape. One mechanism in EffectRenderElement, used by both clip widgets. drawImageRounded takes one radius, so it draws a circle exactly (an oval in a square box is a rounded rect of radius w/2 -- and every ClipOval in the gallery is square, an avatar being as wide as it is tall) and a uniform ClipRRect exactly. A true ellipse, or four differing corners, cannot be expressed that way; those keep the shape clip and now REPORT through FlutterErrorReport where it does nothing, rather than drawing square in silence. Sweep: 48 routes, unchanged -- the desktop keeps the clip path.

The clip bookkeeping asks exactly that question before deciding a setClip changes nothing and can be skipped. Codename One narrows the clip to a component's bounds before painting it, so a circle or rounded rectangle inscribed in that component arrives with bounds equal to the current rectangular clip, compares EQUAL, and is DISCARDED. Shaped clipping is then a silent, total no-op wherever the shape fills its own component, which is the usual case. That is why every round avatar in the transpiled gallery's mail study drew as a square photograph on iOS while the desktop drew circles: only ports whose clip state goes through this comparison are affected, and the desktop's is not. It is also why it survived so long -- nothing is reported, and a screenshot of the simulator looks right. isRectangle() walks the path, so it is asked only once the bounds have already matched, which is the rare case; a clip that genuinely changed is still rejected on the bounds alone. The flutter-runtime side of this commit is the consequence: the clip widgets and Material now use pushClip/popClip, which is the idiom the shaped-clipping tests in scripts/hellocodenameone use and the only one that can restore a shaped clip. Saving getClipX/Y/W/H and restoring with the four-int setClip -- which is what they did -- cannot express a shape, so a nested clip degraded its ancestor's to a bounding box. The layer-and-drawImageRounded workaround added for this two commits ago is removed: with the comparison fixed, the real clip works. Verified on the device: the avatars are circles, drawn through setClip(Shape) with no layer and no rounded-image path. Sweep: 48 routes unchanged on the desktop, which was never affected.

That is right only while subtrees arrive in tree order, and they do not: a LayoutBuilder sits out a speculative measurement pass and builds on a later one, by which time its siblings are already attached.

The bar and the button were not missing or mispositioned -- they were underneath the body, showing only where it did not cover them, which is exactly what "badly layered" looks like. The replacement path already anchored its insertion for this reason; the insert path now does the same. The anchor is the next element in TREE order after the new child: the first of our own later children, and failing that -- the late builder is usually a leaf with no later sibling of its own -- the first later sibling of an ancestor. A Scaffold's body has to be painted under a bottom bar three levels up, which nothing the builder can see would have found. Sweep: /reply 13.80% -> 12.16%, mean 3.58% -> 3.54%, no route regressed.

Codename One reports one as soon as it sees pointer movement, so a control inside a scrollable could be pressed, show its ink, and then do nothing because the finger moved a pixel. Flutter measures the DISTANCE and only stops calling it a tap past kTouchSlop, 18 logical pixels, which is far short of any real scroll. Measured: a scroll drag still correctly fires no tap, and the mail study opens a message on a tap. Separately, and worth recording because it wasted a day: "tapping a mail does nothing" was the HARNESS. benchcn1's bench_pointer floored its `steps` at 1, so every tap it injected carried a drag event -- and it injects those by calling Form.pointerDragged directly, which bypasses Codename One's own drag threshold entirely.

Declare getOuterPath there so a transpiled strategy can be called -- the mail study's WaterfallNotchedRectangle is one, fully transpiled and until now unreachable. The bar is then painted through that outline rather than coloured. A Container fills its box, and the whole point of a notched shape is that the box is not what should be filled; behind the cut-out the page shows through. Two things this cost, worth recording: The geometry is read at PAINT time. The bar is built before the scaffold lays its button out, so at build time there is nothing to read -- Flutter has the same ordering and hands the value over as ScaffoldGeometry a frame late. The fill goes through Graphics.fillShape, not GraphicsCanvas. A canvas draw from this position produces NOTHING -- probed with an opaque magenta box through both a painter and a foregroundPainter, and neither landed anywhere on screen, while the same CustomPaint works on the home screen. fillShape from the same element paints. That is still unexplained and is worth its own look; it is why an earlier attempt through CustomPaint was reverted rather than shipped. Sweep: /reply 12.23% -> 12.06%. The notch is a thin curve, so the metric moves little; it is the difference between a bar that looks like the design and one that does not.

Flutter names an arc by its end point and a radius, the way SVG does, and both path converters replaced it with a straight line -- the note claimed that "keeps the outline closed", which it does, but a chord is not an arc. A bottom app bar's notch is two quadratics either side of one of these, so the dimple curved down, cut straight across, and curved back up. It was reported as "curves then bumps and curves", which is exactly what it was. Solved as SVG does, endpoint to centre, and flattened; a filled path is flattened by the rasteriser anyway. BackButtonIcon.iconData() answered the material arrow unconditionally while build() picked the platform's. The shortcut is the path an extended FloatingActionButton takes for its icon, so the gallery's back button wore Android's long arrow on iOS where the reference wears the chevron -- the wrong platform's glyph, not merely a different shape. Ink stayed lit. Two paths: a forwarded press whose release was withheld when the gesture turned out to be a drag -- the target was told the pointer went down and never that it came up -- and a drag that Codename One hands to the scroller, after which nothing tells the forwarded target anything and a HELD press deliberately keeps its highlight standing. Now the release is always delivered, the cancel is forwarded, the splash drops past Flutter's slop rather than waiting for Codename One's verdict, and the ink's own clock notices a drag took the gesture over. Measured on the desktop: a row goes white again after a scroll, and a real tap opens the mail and returns the row to white. ChangeNotifierProvider never subscribed to its model, so notifyListeners() rebuilt nothing. It does now -- traced firing end to end -- though that is not yet sufficient; see below. Sweep: 48 routes, /reply 12.06% -> 11.90%, mean 2.91%.

Scaffold.extendBody was an EMPTY SETTER -- the flag was read from the widget and thrown away, so the body always stopped above the bottom bar. A bar with a notch then had nothing to reveal through it: the mail study's cut-out came out opaque, showing the scaffold's own background where the list should run underneath. Honoured now, and the notch shows the page. SizeTransition handed its child through at full size; the note called the clip "deferred". So nothing driven by one ever grew or shrank, and the mail study's bottom bar appeared and vanished where it should slide. Built from Flutter's own composition, a ClipRect over an Align whose factor along the axis is the animation's value. It returns the child unchanged at factor 1, which is not an optimisation: Align shrink-wraps once given a factor, throwing away a tight height the parent meant the child to fill. A scaffold stretches its bottom bar over the display's bottom inset, and wrapping unconditionally left that strip unpainted -- /reply 11.94% -> 16.13% before the guard, and back to 11.94% with it. At rest this widget must change nothing. setBgTransparency(0) does not silence a background IMAGE, and Codename One themes routinely give a button a gradient one for its pressed and selected states. An icon button on a dark bar could therefore flash a pale panel when touched or focused. Cleared properly in every state; an icon button has no background of its own in Flutter, its feedback is the ink. Sweep: 48 routes, mean 2.91%, no route regressed.

So when the model notified, the provider element rebuilt itself and achieved nothing: its build hands back the same child WIDGET INSTANCE, reconciliation sees widget == newWidget and returns early, and the subtree that actually reads the value never runs again. Every control whose whole job is to set a field on a model therefore looked dead. Traced end to end on the desktop before and after: the listener fires, the handler runs, the field is set, notifyListeners dispatches, the provider is notified -- and only now does the screen change. The mail study's search button opens the search page. A provider here is an ordinary widget rather than an InheritedWidget, so the dependency Flutter gets for free has to be recorded by hand: readers register with the element they read from, and a notification marks them all for rebuild. Unmounted readers are dropped as they are found, or a popped route would be held alive and rebuilt forever. This is necessary and not always sufficient -- the mail study's bottom drawer toggle goes through setState and animation controllers rather than the model, and still does not open. That is a separate path. Sweep: 48 routes, mean 2.91%, no route regressed.

The difference was not the page but the ancestor chain it was mounted under. A route mounts as its own Form, so it has no real parent; ancestor lookups continue from a fallback element instead, and that fallback was the context that called push(). That is wrong in a way that only shows up under scopes which SUBTRACT: a vertical scroll view wraps its content in MediaQuery.removePadding(top, bottom), because it has already inset its own content by the display cutout and its children must not count it twice. A route pushed from a row inside that list inherited "the top inset is already spent", its SafeArea resolved to zero, and it drew under the status bar. The compose button is a Scaffold slot, outside the list, so it never saw that. In Flutter a route's subtree is built by the Navigator and sits directly under it, so the only ancestors it can see are the ones above the Navigator. Anchor the mount there instead: walk up to the nearest RootScope. Nearest matters -- a study is a MaterialApp of its own wrapped in the providers it needs, so anchoring at the outermost app's scope climbs out of the study's MultiProvider and the page's first Provider.of returns null, which is a null-check crash while building _MailViewHeader rather than a layout defect. MediaQuery.formOf and EffectRenderElement now find the Form by walking up through ancestors, so a nested host inherits it rather than reporting no Form and falling back to the raw display metrics. Two tests pin the rule: a route pushed from inside a removePadding scope still sees the display padding, and the nearest navigator scope wins.

The tap registered, the state flipped and the drop arrow turned, but no panel was ever built -- which reads as "the button does nothing" and, once the arrow is up with an empty screen behind it, as "there are no subpages". The drawer is a Visibility gated on the drawer controller being forward or completed, and the rebuild that re-evaluates it comes from a listener the app installs on that controller: _drawerController = AnimationController(...) ..addListener(() { if (_drawerController.value < 0.01) { setState(() {}); } }); That reads as a listener for the END of the closing animation, but it is also the only thing that rebuilds the Stack when the drawer OPENS, and it can only fire then if a notification arrives while the value is still at zero. Flutter guarantees one: the Ticker calls back on its first frame with an elapsed of zero and _tick notifies unconditionally. We skipped that notification, on the reasonable-sounding grounds that the first tick only establishes t = 0 and the value has not moved. So the first call any listener saw was already a frame in, at 0.03 for a 300ms run against a threshold of 0.01, and setState never ran. The first tick is now one method, used by the framed path and by the headless collapse alike, so a controller behaves the same way in a test as on a device rather than only appearing to. Verified in the simulator: the panel now slides 1895 -> 1557 -> 1261 -> 977 -> 942 over ~300ms instead of never appearing. Route sweep unchanged at 2.91% mean.

There is only one path, and it is worth stating once: the port answers Form.getSafeArea, MediaQueryData turns that into padding, FlutterUI turns CN1's own safe-area layout off so the inset is never applied twice, and a widget that spends part of the padding removes what it spent for its descendants. The invariant that falls out is that the padding is applied exactly once along any path from root to leaf, and the two ways to break it are both things that have actually happened here: insetting outside the chain, and carrying a subtraction across a boundary where it does not belong.

        2. + *
      2. {@code MediaQueryData.fromDisplay} converts that rectangle into {@code padding} once, + * turning device pixels into logical ones. Everything downstream reads padding and never + * asks the port again.
        3. + *
      3. {@code FlutterUI.stripChrome} turns Codename One's own safe-area layout OFF + * ({@code Container.setSafeArea(false)}). CN1 would otherwise hold the content off the + * cutout as well, and the inset would be applied twice -- which shows up as a band of the + * Form's colour above everything the app drew.
        4. + *
      4. A widget that spends some of the padding removes what it spent for its + * descendants, via {@code removePadding}: the Scaffold body drops the top when an AppBar + * stands in for it and the bottom under a bottom bar, and a scroll view drops its own + * axis after padding its content. {@code SafeArea} then applies whatever is left.
        5. + *
      + * + *

      Because every consumer subtracts rather than recomputes, the invariant is that padding + * is applied exactly once along any path from the root to a leaf. Two things break it, and + * both have:

      + * + *
        + *
      • Insetting outside this chain. Any port-specific "hold it off the status bar" + * is a second application. The answer is always to read {@code MediaQuery.padding}.
        • + *
      • Carrying a subtraction across a boundary it does not belong to. A route is + * mounted with a fallback ancestor, and using the widget that pushed it let a scroll + * view's {@code removePadding} leak into the new page, whose SafeArea then resolved to + * zero. Routes anchor at the nearest navigator scope for this reason -- see + * {@code Navigator.pushingElement}.
        • + *
      + * + *

      The rule is verified on desktop and iOS by opening a study, pushing a page out of a + * scrolled list, and checking that the pushed page starts at the inset rather than at zero.

A route is a Form of its own, and Navigator.push showed it with no transition set, so the Form replaced the screen outright: measured from a mail-row tap, the destination page was already fully painted 170ms later, with nothing in between. Flutter always animates a route in, and picks the animation from PageTransitionsTheme and the target platform. RouteTransitions follows that table -- Cupertino's 500ms slide from the trailing edge on iOS and macOS, ZoomPageTransitionsBuilder's 300ms fade elsewhere, a modal up from the bottom edge, and a cross-fade for an OpenContainer, which is the honest approximation of a container transform when the two halves are separate Forms. Only the entering transition is set, because showBack() plays it in reverse for the pop and a second mapping would be one more thing to keep in step. Note CommonTransitions names a slide's direction after the OUTGOING page: paintSlideAtPosition moves the source by +position when forward is true, so forward brings the new page in from the LEADING edge, which is the way back. A push is forward=false. Getting this backwards is invisible in a still. Separately, AnimationController.animateTo and animateBack accepted a Curve and dropped it, so every eased call ran linear -- including Reply's animateTo(0.4, curve: Easing.legacy) for its drawer, which is meant to ease in and settle and instead started and stopped abruptly. forward, reverse and fling stay linear, as they are in Flutter; the curve now rides with the run and shapes it per frame. Verified by capturing the screen from outside the app, so the frames are not serialised behind the EDT: the mail push cross-fades with the inbox visible through it, and the compose push does the same. Route sweep unchanged at 2.91% mean.

It was not missing. All six cards were mounted, at the list's origin, inside panes of zero size -- and a zero-sized pane clips the subtree it hosts, so the list was invisible rather than merely stacked. Nothing recovered it; every later pass hit the same clean cache. Opening the mailbox drawer happened to fix it, which is what made the shape of the bug visible. A build flush collects the hosts it must lay out from the subtrees it rebuilt, and does that BEFORE laying anything out. That assumes every host exists by then. Not all do: a LayoutBuilder sits out a speculative measurement and inflates its subtree on a later pass -- during the very revalidate the flush is running -- and each thing it inflates can bring a host of its own, an effect pane or a scroll pane. Those hosts were never in the set, so they were never laid out, and the elements inside them kept the offsets their parent stored while they still measured zero. Coming back from search rebuilt two elements and found seven hosts; the mail list underneath owns thirty, one per card, every one of them created while those seven were being laid out. So look again after the pass, and lay out what appeared during it, bounded so a tree that somehow keeps producing hosts cannot loop. Two supporting changes, both about an invalidation arriving mid-pass: updateChild now marks the enclosing layout dirty when a child is inflated or dropped, since a cached layout is only valid for the children it was measured over and a child inflated during layout never goes through the rebuild queue at all; and a box invalidated WHILE it is being measured no longer clears needsLayout on its way out, which silently discarded exactly those marks. Only structural changes invalidate -- treating every rebuild as a layout change is what made the carousel stutter. Route sweep unchanged at 2.91% mean.

We did none of it, and three separate links in that chain were missing. Nothing ever raised a ScrollNotification. The classes were all there and Notification.dispatch was a stub returning false, so every NotificationListener in the gallery was inert. A scroll view now reports the direction of a drag and the notification bubbles to the listeners above it, innermost first. depth counts the scroll views it passed THROUGH, not the listeners, because that is the distinction the app reads: Reply acts on depth 0 so that dragging the image carousel inside a mail card -- a scroll view of its own -- does not move the bar. Direction comes from the drag and only from the drag. Flutter raises this when a drag starts or ends, so momentum, the settle at the end of a fling and the bounce at an edge never speak. Reading them was not a small error: reading down overshot to 666 and settled back to 609, so the drag ENDED by reporting the direction opposite to the one the user made, and dragging back up bounced past zero and reported the other one. The bar folded when you scrolled to the top and reappeared as you read on -- the right animation, driven backwards, which is worse than none. And CurvedAnimation never followed its parent. Its own javadoc said listener registration forwards to the parent; addListener was inherited unchanged, so it filed listeners on an object nothing ever notified. A CurvedAnimation has no clock of its own -- it only reshapes another animation's value -- so anything animated through a curve sat at whatever value it was built with. That is most of the gallery's motion, the bottom bar included. Verified in the simulator: reading down folds the bar 168 -> 244 -> 102 and scrolling back restores it 266 -> 168, both over their own duration. Route sweep unchanged at 2.91% mean.

The inset was in the wrong place. We had the bar at exactly its Material height and let the Scaffold paint a band behind it to cover the display's bottom padding -- which is indistinguishable from the truth in a still, and wrong the moment the bar moves, because the band is not part of what folds. Flutter puts it inside: BottomAppBar wraps its child in a SafeArea, so the bar MEASURES its height plus the inset, and anything applied to the bar applies to both. The bar now does the same and the Scaffold adds a band only when there is no bar to carry one. At rest nothing changes -- the bar is still 342 device pixels flush with the bottom edge, and /reply scores what it scored before. Folded, it now goes to nothing, and unfolding runs 0 -> 336 monotonically rather than arriving in a step. Also: the FAB kept the drop shadow its Codename One border draws for itself. Elevation belongs to the Material surface underneath, which is what Flutter shades and what a notched bar already accounts for, so the border's own shadow was a second harder ring -- reading as a smudge around the notch cut-out rather than as lift. Only the shadow is cleared; the theme still owns the shape and the stroke.

In the reference the button GROWS into the page and folds back into itself on the way out; we cross-faded on the way in and slid on the way out, which is two different animations for one gesture and neither of them the right one. Codename One has this natively and I had written it off as something we could not do. BubbleTransition expands the destination Form out of a named component in the outgoing one, which is exactly a container transform, so an OpenContainer route now carries the name of the surface it came from and the transition grows the page out of it. The name is assigned when the container is TAPPED, not when it is built. It has to identify the one surface the user actually touched -- a mail list is a column of these -- and widgets are rebuilt often enough that a name handed out during build belongs to whichever instance built last. The element under the tap's context is stable and is the one on screen. The way out mirrors the way in. showBack() plays the transition of the form being RETURNED TO, in reverse, and that form carries whatever animation brought IT on screen -- which has nothing to do with the route being dismissed. That is why closing compose slid the inbox in from the side after compose had grown out of the button. The popped route's transition is now applied to the form being returned to, so the pop is the push backwards. Verified by recording the iOS simulator and stepping the frames: tapping the button opens a circle at the button that grows until the compose page fills it, and closing contracts the same circle back onto the button. Route sweep unchanged at 2.91% mean.

It is not a pushed route -- Reply swaps the search page in for the mail navigator through a PageTransitionSwitcher, with a SharedAxisTransition to animate it -- so the whole animation of opening search lived in this widget, and this widget hosted its child directly and ran nothing. SharedAxisTransition was already written and correct; it was simply never given an animation to read. The state lives on the element, not the widget. A widget is rebuilt whenever anything above it changes, so a controller kept there would be new on every frame and the transition would restart forever; the element survives those rebuilds, which is what lets it notice that this child is not the one it had. "Not the one it had" is Flutter's canUpdate: same type and key updates in place and is not a transition. The controller starts SETTLED. The first child was not switched to, it was always there, and a transition reading its animation at zero draws the page fully transparent and scaled away -- every screen built through a switcher came up blank and stayed blank. Measured before that was fixed: the bottom-navigation demo went from 4.6% wrong to 39%, and /reply from 11.9 to 20.8. With it, the sweep is byte-identical to before this change on all 47 routes. Only the incoming half runs. Animating the outgoing half too needs both children mounted at once, and a child here is a whole page, so it would double the tree for the length of the run; the incoming half is the half that reads as the transition. Recorded on the iOS simulator: search now fades and scales into place over six frames where it used to appear in one.

AppBarTheme is the one that showed first -- its getters were gone, so every caller in AppBarRenderElement stopped compiling. Two real merge wounds in shared files: - CodenameOneImplementation.drawImageRounded lost its closing brace. Master added the method and this branch added createImageNoBackingCopy directly after it, so the conflict boundary fell between the body and the brace and keeping both sides kept neither whole. - Display.edtLoopImpl declared `t` twice. Master added a timer clock at method scope; this branch's EDT trace blocks each declare their own `t` inside an if, which was legal when they sat above master's declaration and is not now. Both are renamed rather than reusing the outer one, since they measure different things. Verified: the core builds under JDK 8, and dart-runtime, dart-transpiler and flutter-runtime build and pass under JDK 17 -- 20, 47 and 383 tests, the same counts as before the rebase.

      Per-vertex colour interpolation (Gouraud shading) is not modelled; a
+     * multi-coloured triangle takes its first vertex's colour. The blend mode is
+     * ignored — Codename One composites source-over.
+     *
+     *

+     * out at a third of its size on a 3x screen.

Subject: [PATCH 144/333] Drop the no-backing-copy image feature the merge
 resurrected

Resolving conflicts by keeping both sides brought back a feature this branch
had already reverted. IOSImplementation gained a createImageNoBackingCopy
override calling IOSNative.markImageNoBackingCopy, the core gained the
default it overrides, and applicationDidEnterBackground called
EncodedImage.invalidateDecodedImages -- none of which exist any more on
either side, so the iOS port stopped compiling on three missing symbols.

Master and this branch's own tip agree the feature is gone; only the merge
thought otherwise. Also removes the second getDevicePixelRatio the same
resolution duplicated: the surviving one asks the platform for its scale,
which the version removed here gets wrong, and says so in its own comment.

The JDK 8 half of the tree now builds clean.

Subject: [PATCH 145/333] javase: restore the blit trace the rebase dropped

An off-by-default measurement of where a simulator frame's time goes -- how
long the buffer copy takes against how long the present takes -- behind
-Dcn1.blit.trace. Nothing runs unless the property is set.

It was lost during the rebase onto master rather than removed on purpose:
rerere resolved the file toward master, which does not have it, and the
commit that carried it then applied as empty and was dropped. Cherry-picked
back with rerere disabled, since its recorded resolution was the thing
discarding it.

Subject: [PATCH 146/333] vm: remove a conflict marker the rebase left in
 cn1_globals.m

A stray ======= survived my resolution of that file and went straight into
the generated project, where it is a syntax error in C: the iOS build stopped
at cn1_globals.m with "expected identifier or '('". It got that far because
nothing looks for markers -- the resolver I was using asserted only that
<<<<<<< was gone, which it was.

Subject: [PATCH 147/333] flutter-runtime: make motion measurable, and report
 the platform being simulated

Comparing motion against another stack only means something if both are asked
for the SAME animation time. Against the wall clock they never are: a frame
lands when it lands, and two recordings of one gesture are two different
samplings of it. Flutter's widget tests own the clock -- tester.pump(d)
advances animations by exactly d -- and that is how the reference frames this
port is measured against are captured.

MotionClock does the same here. Frozen, a harness names an animation time,
every running controller is advanced to it, and the frame painted is the
frame at that time; controllers still compute their own progress from it, so
what is compared is still this runtime's real curve and duration arithmetic.
Released, which is how an application always runs, it is
System.currentTimeMillis() and costs one boolean test per tick. FrameDriver
stays package private -- an application has no business pumping the frame
clock by hand -- and MotionClock.advanceAndPump is the single door.

Separately, defaultTargetPlatform can now be told what device this build is
standing in for. It decides the back chevron against the arrow, page
transitions, switches and scrollbars, and the JavaSE simulator reports "SE",
which fell through to android -- while the skin it wears and the reference it
is measured against are both an iPhone. Every one of those adaptive widgets
disagreed and none of the disagreements were defects. The static sweep does
not move (2.91%, unchanged), because only the back icon of those is visible
in a settled frame and it already matched; what it changes is the motion,
where our desktop used to cross-fade a page push the reference slides.

And cn1:run now hands every cn1.* system property to the simulator. It runs
in a JVM of its own, so -Dcn1.anything set on Maven reached nothing the
application could read, which looks exactly like the property being ignored;
only ffmpeg.dir was forwarded, one key at a time. Scoped to that prefix
because Maven's own properties mean something different inside a fork.

Subject: [PATCH 148/333] flutter-runtime: an animateTo covers part of the
 range in part of the time

A controller's duration describes crossing its WHOLE range. Flutter scales an
animateTo that is given no duration of its own by the fraction it actually
covers -- _animateToInternal's directionDuration * remainingFraction -- and
we ran every one of them for the full duration instead.

Reply opens its mailbox drawer with animateTo(0.4) on a 300ms controller,
which is a 120ms animation. At 300ms it arrived two and a half times too
late, and the drop arrow beside it and the search page behind it were slowed
by the same error.

Measured against the reference frame by frame, at the same animation times:
the drawer's worst frame went from 50.6% of the screen wrong to 11.8%, and
the middle of the transition -- 100ms through 300ms, where the two were
50/28/14/8% apart -- settled to a flat 6.3%, which is the static floor for
that screen plus the remaining differences at the very start.

An explicitly given duration is still used whole, and Flutter's refusal to
animate to where it already is comes with it.

Route sweep unchanged at 2.91% mean.

Subject: [PATCH 149/333] flutter-runtime: the floating action button scales in
 and out

Flutter's Scaffold runs every change of that slot through
FloatingActionButtonAnimator.scaling over kFloatingActionButtonSegue. We
dropped the widget outright, which is a visibly different thing: Reply hides
the button while its mailbox drawer opens, and the reference still shows it
50ms into the gesture and has scaled it away by 100, where ours was simply
gone on the first frame -- the button did not leave, it was never there.

The exit needs the outgoing button kept alive until it has finished leaving,
since nothing else holds it once the app stops handing it over. A scaffold
that opens WITH a button starts at full size rather than scaling one in,
because there was no change to animate.

Verified frame by frame against the reference at the same animation times:
ours now shows the button full at 0ms, smaller at 50 and nearly gone at 100,
which is what the reference does.

Route sweep unchanged at 2.91% mean; 389 runtime tests pass.

Subject: [PATCH 150/333] Capture a form transition by asking Codename One for
 it

Page transitions were the one thing the motion harness could not measure. I
had put that down to them being form transitions rather than widgets, and
concluded the fix was to move them into the Flutter tree. That was wrong:
the framework already has both halves.

AnimationTime is Codename One's pluggable animation clock, and its whole
reason for existing is deterministic playback -- stepping animations by hand
for tests. MotionClock is now a thin face over it rather than a clock of its
own, so a Flutter animation and the FORM TRANSITION carrying the page it
lives on advance together off one time source. Separately they did not: with
the widgets held still the transition around them ran on regardless, so a
captured frame was half of one moment and half of another, and a page push,
which is entirely a form transition, did not hold still at all.

Display.getRunningTransition is the other half, the companion to the
isInTransition it sits beside. A transition paints the frame BETWEEN two
forms, so neither form can be asked what is on screen while one runs: the
destination gives the finished state and the source the state before it
began. Painting the destination is why every sampled frame of a push came
back already settled.

One constraint worth recording, because it looks like a hang: Codename One
runs a form transition by spinning the EDT until the animation queue drains
(Display.flushEdt). With the clock held, that queue cannot drain, so
anything handed to the EDT and waited on deadlocks. The harness fires the
action without waiting and takes the frame from its own thread; a
transition's paint only reads, so that is safe.

Page pushes are now measured like everything else. The three in the suite
come in at 21.4%, 13.7% and 13.3% of the screen wrong at their worst frame,
where before they could not be sampled at all.

389 tests pass; route sweep unchanged at 2.91% mean.

Subject: [PATCH 151/333] core: a transition's motion must survive being copied

CommonTransitions.setMotion is public API, documented as the way to give a
transition "a more appropriate physical feel". It never reached the screen.
Display copies a transition before running it, and copy() carried only
linearMotion -- motion, lazyMotion and the motionSetManually flag that
selects them were all dropped, so the default ease ran instead. Silently: the
transition still played, just not the one that was asked for.

Found by giving the Flutter port's page push Flutter's own curve
(Curves.linearToEaseOut) and measuring no change whatsoever against the
reference -- the same three numbers to two decimal places, before and after.

With the motion arriving, the page push now travels the way the reference
does: measured frame by frame at the same animation times, the worst frame of
a push falls from 21.4% to 16.8% of the screen wrong for Reply, 13.7% to
11.7% for Shrine and 13.3% to 11.8% for a demo page. Same distance, same
500ms; what changed is the shape of the travel between them.

389 tests pass; route sweep unchanged at 2.91% mean.

Subject: [PATCH 152/333] flutter-runtime: a page switch shows the page it is
 leaving

PageTransitionSwitcher built only the incoming child, so a shared-axis
transition -- which fades the outgoing child out over the first part of the
run and the incoming one in over the rest -- had nothing on screen at all
until the run was a third done. Opening search began with a blank flash where
the reference dissolves one page into the other.

Both are built now, the outgoing one under the incoming one, and the
transition decides what that looks like: it is handed the outgoing child as
arrived (primary complete) and leaving (secondary running), which is the
shape the animations package gives it.

Measured at the same animation times, the first frame of opening search goes
from 21.2% of the screen wrong to 12.1% -- which is the inbox's own static
difference, so that frame is now as close as the screen behind it allows. The
worst single frame rises to 25.1% at 50ms while the mean over the sequence
falls, which is why the comparison now reports both: one frame in ten being
wrong reads as a glitch, every frame being slightly wrong reads as the wrong
animation, and a change can improve the second while worsening the first.

Route sweep unchanged at 2.91% mean.

Subject: [PATCH 153/333] core: a container transform, because a circular
 reveal is a different animation

Material's container transform is the one where a card or a button BECOMES
the page it opens. The closest thing we had was BubbleTransition, a circular
reveal: a round hole opening from the centre of the destination. Different
shape, different anchor, different reading -- a window opening rather than an
object transforming -- and measured frame by frame against Flutter it was the
worst step in the suite by a wide margin.

ContainerTransformTransition is the transition that animation actually is: a
rounded rectangle travels from the tapped component's bounds to the whole
form with its corners straightening, the page behind dims, and the two
contents cross over inside it. Unlike MorphTransition it needs a counterpart
on only ONE side, which is the usual case -- a button does not reappear on
the page it opened.

Three things in it are easy to get wrong and each was worth several points
when measured:

- Geometry follows a fast-out-slow-in curve; the colours and opacities do
  NOT. Material drives them off the raw animation in fifths -- dim over the
  first, cross the surface colour and the incoming content over the second,
  settle through the rest. Fading on the curved value crams the whole
  crossover into the first fifth of the travel, where the box is still small.
- The page behind has to be dimmed. Without the scrim the whole background
  stays at full brightness for the whole run, which is far more pixels
  disagreeing than the surface itself ever accounts for.
- The tapped component is snapshotted WITH its background. A button's colour
  usually comes from its border or a painter rather than from bgColor, so
  without it the surface is pale where the reference's button is still its
  own colour, and the snapshot is a bare glyph.

Measured at the same animation times, the compose step's mean falls from
28.6% of the screen wrong to 16.7%, and every frame from 100ms on now matches
the reference frame of the same instant more closely than any other frame of
it -- the timing is right and what is left is the first 50ms.

389 tests pass; route sweep unchanged at 2.91% mean.

Subject: [PATCH 154/333] flutter-runtime: lay a line of text out at the height
 the FACE says

The worst route in the sweep was the mail study at 11.9% of the screen wrong,
and none of it was the widgets. Its card is three lines of text; each was
about three logical pixels short, so every card came out 26 device pixels
shorter than the reference and the list drifted further out of place the
further down it went. Measured: the card's content is 128 logical pixels in
the reference and was 119 here.

A text style that names no height gets the FONT's line height, and which of a
font's several vertical metrics that means is not settled between platforms.
Codename One reports the typographic pair, which for Work Sans is 1.17 em --
faithful to sTypoAscender + sTypoDescender, and not what Flutter lays the
same file out at. The pair that reproduces the reference is the WINDOW ascent
with the typographic descent, 1.35 em here, which matches what it measures to
within a pixel over three lines. Read from the face itself, so a font with
different metrics gets its own answer rather than this one's.

Separately, a theme that names no typography now resolves to the Material 3
scale instead of an EMPTY text theme. Nothing was returning sizes at all in
that case, so every role fell back to whatever the font measured.

/reply falls from 11.94% to 5.06% and the sweep mean from 2.91% to 2.74%.
/demo/typography rises 7.94% to 9.50% and is now the worst route; its sample
text has rendered smaller than the reference since before any of this, which
is a separate defect this change makes more visible rather than one it
introduces.

389 tests pass.

Subject: [PATCH 155/333] flutter-runtime: resolve a theme's text styles
 instead of returning them raw

ThemeData.textTheme() handed back the application's own TextTheme exactly as
it was given, so a theme that overrode two roles had two roles and every other
one was empty. The reference resolves the typography for the theme's
brightness first and merges the application's overrides onto that, and its
TextStyle.merge keeps a base field the override leaves null -- which is how a
role that states a size and no height still lays out at the scale's height.

Cache the resolved answer rather than the raw field, and merge in that order.

Measured over the 47-route sweep: mean 2.91% -> 2.67% wrong pixels, and /reply
leaves the worst-route list entirely (it was 11.94%, the worst screen in the
app, because its styles were resolving without the scale behind them).

Subject: [PATCH 156/333] flutter-runtime: read a face's line height the way
 the face asks for it

metrics() computed (usWinAscent + |sTypoDescender|) / unitsPerEm, which is not
a pair any font declares. usWinAscent is the ink bound of the tallest glyph
rather than an ascent, so pairing it with the typographic descender describes a
box taller than either of the face's own pairs.

A font carries two competing pairs and bit 7 of the OS/2 fsSelection field
(USE_TYPO_METRICS) is the author stating which is authoritative: set, the
typographic pair wins, line gap included; clear, hhea does. Follow that.

The error was only reachable from text whose style states no height, so the
type scale hid it for nearly every role -- and it stays dormant for a style
that also names no family, since there is then no file to read the metrics
from. Corrected here because it is wrong wherever it does fire, not because it
moved the sweep: it did not, to two decimal places.

Subject: [PATCH 157/333] Drive the container transform's scrim off the curve,
 and close on its mirror

Two defects in one transition, both of which the motion suite could see.

The SCRIM was ramped against raw elapsed time while Material ramps it against
the curved animation, as it does the rectangle. Every other quantity here was
already right -- the opacities and the surface colour ride the raw clock, and
they still do -- so this was one term out of four. It was also the expensive
one to get wrong: the scrim covers the entire screen, so while it is ramping,
being at the wrong point on the curve puts every pixel at the wrong
brightness.

Measured at the 50ms frame of the 300ms run, mean luma over the screen: the
raw clock predicts 116.6 and we rendered 117.3; the curve predicts 163.4 and
the reference rendered 163.2. That frame was 82.84% wrong pixels, sitting
between neighbours at 5% and 13%.

CLOSING also ran on the opening curve, because copy(reverse) dropped the flag
on the floor and built an identical instance either way. Material closes on the
mirror of the opening curve, so the rectangle should leave slowly and arrive
fast -- the opposite of how it opened. Mirroring a cubic bezier is exact rather
than approximate: 1 - f(1 - t) maps control points (x1,y1,x2,y2) to
(1-x2, 1-y2, 1-x1, 1-y1).

reply_compose over the whole run: mean 15.20% -> 7.17% wrong pixels, worst
82.84% -> 13.03%.

Subject: [PATCH 158/333] flutter-runtime: make the ink a ripple again rather
 than a grey flash

The press effect read as the row flashing flat grey instead of as a circle
travelling out from the finger. Three separate reasons, none of them a missing
feature -- the splash and the highlight were both already here.

TIMING. The splash grew over 320ms. Material grows an unconfirmed ripple over a
full second and only finishes it quickly (225ms) once the tap is confirmed, and
it starts the disc at 30% of its target rather than at nothing. Growing it in a
third of a second from zero means the circle has covered the target before the
eye finds it, which is precisely the reported symptom. The fade in (75ms) and
the fade out (375ms, holding full opacity for the first 225ms of that) were
missing too, as was the ease curve -- the runtime already had Curves.ease, and
this was using a quadratic of its own.

CLOCK. It read the wall clock, so it was the only animation on screen that a
frozen clock could not hold still: asked for the frame at 100ms it showed
however far real time had carried it, saturating within two frames and then
sitting there. That is ink arriving too fast on a device and not reproducible
at all in a test. It rides the animation clock now, like every other animation.

WEIGHT. An explicit splash colour had its alpha masked off, so a caller's ink
always painted at the default weight. Fixed by carrying the colour as ARGB.
Note the defaults deliberately do NOT follow ThemeData's splashColor and
highlightColor (40% of a light grey): those are the Material 2 fallbacks, and
trying them made it worse -- at 100ms into a press the reference's mail card is
still clean white while a 40% wash covered the whole card, text and icon
visibly greyed. What a Material 3 ink paints is a much lighter state layer.

reply_card_press over the whole run: mean 8.96% -> 4.45% wrong pixels, worst
18.36% -> 8.09%. reply_drawer came along with it, 5.34% -> 5.17%.

Subject: [PATCH 159/333] flutter-runtime: a line box is ascent plus descent,
 not the font's line spacing

A text style that states no height fell back to Font.getHeight(), which is the
platform's recommended line SPACING -- ascent, descent and external leading.
The reference's line box for such a style is the face's own ascent and descent,
which is a different quantity and a smaller one wherever a platform is generous
with leading.

Measured neutral on the sweep (mean 2.67% either way) because this port answers
getAscent() + getDescent() with exactly getHeight(), so nothing moved here.
Corrected because it is the wrong quantity to ask for, and a port that
distinguishes them would lay every such style out at the wrong leading. The
fallback to getHeight() remains for a port that cannot answer for the face at
all.

Subject: [PATCH 160/333] flutter-runtime: a Scaffold establishes the text
 style for what it contains

A Scaffold is a Material, and a Material is what sets the default text style
for its subtree. Ours set none, and nothing else did either under a nested
theme: a Theme is an inherited widget and wraps nothing, so installing one
changes what Theme.of answers while the ambient text style stays exactly as
whoever built it last left it -- the application's.

The effect is not that a page ignores its theme, which would have been noticed.
It is that a page takes from its own theme only the fields its styles actually
set, and silently keeps the application's for the rest, because a Text merges
its own style OVER the ambient one. So sizes came from the right theme and
family and line height came from the wrong one.

The typography demo is the clean case, since it renders the type scale itself.
Its 96sp display role states no height and no family, so it inherited the
application's Montserrat at a line height of 1.43 -- a body role's height
applied to a display role. Its two wrapped lines sat 141 logical pixels apart
against the reference's 115, and every item on the page compounded the error,
so the further down the page, the further out of register it went.

/demo/typography: 9.76% -> 7.52% wrong pixels, which takes it off the
over-target list; the sweep mean goes 2.67% -> 2.65% and the routes above 8%
drop from two to one.

Recorded honestly: /demo/motion goes the other way, 4.35% -> 6.21%. Its text
now resolves against the demo's theme rather than the application's, which is
the correct answer and measures worse, so something below it is reading the
wrong role -- worth a look on its own rather than a reason to keep the ambient
style wrong everywhere else.

Subject: [PATCH 161/333] flutter-runtime: size a list tile by its line count,
 not by its avatar

A list tile's height comes from how many LINES it has. The leading and trailing
widgets are centred inside that height and are allowed to overflow it; they
never drive it. Ours took the tallest of text, leading and trailing, so a tile
was as tall as whatever was in it.

Crane's destination list is where it showed. Its rows carry a 60lp thumbnail,
which with the vertical padding came to 76lp against Material's two-line height
of 72lp. Four logical pixels a row does not look like anything on one row, but
the rows below it each start 4lp lower than the row before, so the list drifts
steadily out of register with the reference -- 43 device pixels by the fourth
row, which is most of a line of text.

Two-line height (72lp) was also simply missing: every tile used the one-line
minimum of 56lp, so any tile whose content happened to fit was the wrong height
even without a leading widget. The existing test asserted 56lp for a tile it
built WITH a subtitle, which is why nothing caught it; updated to 72lp, with
the child offsets that follow from it.

The text may still push a tile past its nominal height -- that part Material
does allow -- so this keeps the max against the text block and drops it only
for the leading and trailing.

/crane 8.69% -> 7.64% wrong pixels, /demo/motion 6.21% -> below 4.6%, sweep
mean 2.65% -> 2.58%, and no route in the gallery is over 8% any more.

Subject: [PATCH 162/333] flutter-runtime: ease the shared-axis transition, and
 let the outgoing child grow

Two things were missing from the scaled variant, and together they were the
worst single frame in the motion suite.

Every leg of this pattern is EASED, on three different curves: the arriving
content decelerates in (0, 0, 0.2, 1), the leaving content accelerates out
(0.4, 0, 1, 1), and both scales run on the standard curve (0.4, 0, 0.2, 1).
All three ran linearly here. Linear is not a small difference on a fade that
only occupies the first three tenths of the run: a third of the way through
that window the curve has taken the outgoing surface most of the way out while
linear has barely started, so the frame still looks like nothing has happened.

The outgoing child also never scaled. It should keep growing, through 100% to
110%, while the incoming one comes up from 80% -- that continuing motion is
what makes the two read as one surface handing over rather than as a
cross-fade. Ours pinned it at 100% for the whole run, because the scale was
computed from the incoming animation only, which for the outgoing child sits
at 1 the entire time.

reply_search: worst frame 21.77% -> 4.42% wrong pixels, mean 5.96% -> 4.00%.
It was the worst step in the suite and is now the best.

Subject: [PATCH 163/333] flutter-runtime: ease the fade-through transition's
 two legs

Same defect as the shared axis, in the pattern beside it: the fade-through
leaves on one curve (0.4, 0, 1, 1) and arrives on another (0, 0, 0.2, 1), and
both legs ran linearly.

The old page is the one you watch here, since it carries the whole screen for
the first three tenths while the new one is still invisible: a third of the way
into that window the curve has it 58% gone where linear has it at 44%.

Measured no change on the suite, and the reason is worth recording rather than
leaving for the next person to re-derive: the step named "search" exercises the
SHARED AXIS transition, not this one. This is the Reply body's own switcher,
which no step drives yet. Corrected on the strength of the pattern's own
specification.

Subject: [PATCH 164/333] Push an iOS page in on the curve the arriving page
 actually uses

The platform page push ran the incoming page on linear-to-ease-out. That is the
curve of the page being LEFT, and of the shadow; the page arriving rides
fast-ease-in-to-slow-ease-out, which is a three-point cubic -- two beziers
joined at a point, accelerating hard to half its travel in the first fifth of
the run and then changing character and settling slowly.

A single cubic cannot express that, so Motion gained
createThreePointCubicMotion. Each segment is solved in its own normalized space
and rescaled, which is what makes the halves meet exactly at the joint rather
than step there.

This was hard to see because both curves start at 0, and both finish at 1 at
exactly 500ms: the error is invisible at either end and worst in the middle.
Measured against the reference as a fraction of travel completed, where our own
motion tracked linear-to-ease-out to within 0.3ms at every sample:

    ms     reference   three-point   linearToEaseOut
    50        0.2382        0.2383            0.2615
   150        0.7600        0.7604            0.7195
   250        0.9422        0.9422            0.9201

rms error over the run: 0.0005 against 0.0266. In pixels that is a whole page
sitting 46 device pixels from where it belongs halfway through every push.

push_reply mean 8.84% -> 5.81% wrong pixels (worst 13.08% -> 10.69%),
push_shrine 5.68% -> 5.14%, push_demo_app_bar worst 11.62% -> 11.16%. Every
step in the motion suite is now under the 8% target.

Known gap, recorded rather than papered over: the outgoing page should ride
linear-to-ease-out while the incoming one rides this, but a Codename One slide
drives both pages from a single Motion, so both share this curve. The outgoing
page travels a third of the distance, so the residual there is a third the size.

Subject: [PATCH 165/333] Give the iOS push its parallax: two pages, two
 distances, two curves

The platform push was a slide, and a slide is the one thing this transition is
not. A slide holds the two pages a fixed screen apart and moves the pair, so
they travel as one rigid object. On this platform the arriving page crosses the
WHOLE screen while the page it covers drifts only a THIRD of it, each on its
own curve, and the gap between them closing as they travel is exactly what says
one is in front of the other.

Moving both the full distance is not a subtle error. A third of the way through
a push, the strip of the old page still showing is not dimmer or slightly
shifted -- it is a different PART of that page. Measured at 150ms of a 500ms
push on a 1125px screen, by correlating each side's strip against its own
pre-transition frame:

    ours   old page 855px to the left   (full width * three-point curve)
    ref    old page 270px to the left   (width/3  * linearToEaseOut)

Both figures land on their formula exactly, which is what identifies the defect
rather than merely measuring it.

CommonTransitions cannot express this -- one Motion drives one offset -- so
this is a transition of its own, alongside the container transform. It buffers
both pages and places them independently, and copy(reverse) swaps which one
crosses the screen and which drifts home.

    push_reply        mean 5.81% -> 3.47% wrong pixels, worst 10.69% -> 4.12%
    push_shrine       mean 5.14% -> 2.83%, worst 10.58% -> 3.33%
    push_demo_app_bar mean 7.54% -> 5.24%, worst 11.16% -> 6.42%

Against where the pushes started, push_reply was 9.50% mean and 13.37% worst.

Known gap: the reverse plays on the forward curves rather than the flipped
ones the platform specifies. No step pops a route yet, so that is unmeasured
here and left rather than guessed at.

Subject: [PATCH 166/333] flutter-runtime: make a collapsed input decoration
 actually collapse

InputDecoration.collapsed kept only the hint text and dropped everything that
makes it collapsed, so the result was indistinguishable from a plain
InputDecoration and every such field still drew the full outlined box. No
border and zero padding are the POINT of the factory, not defaults it happens
to inherit.

Reply's compose screen is where it showed: its subject line and its message
body both sat in outlined rectangles where the reference has neither -- the
reference draws only the text, with the section dividers below supplying the
horizontal rules.

The styling arguments the factory already accepted were also being discarded
rather than applied, so an explicit border, hint style, fill or fill colour
passed to collapsed() did nothing. They are applied now, with the explicit
border still able to override the none default.

reply_compose settled frames 5.82% -> 5.32% wrong pixels, mean 7.17% -> 6.76%.

Subject: [PATCH 167/333] Fix the elevation shadow's weight, and make the
 container transform close

Two defects a whole-screen percentage could not see, both found by using the
app rather than by reading a number.

THE SHADOW. paintShadowRings stacks four FILLED shapes, so each ring darkens
everything inside it as well as its own band, and all four used one alpha. The
band against the surface was therefore hit four times and came out about twice
as dark as Material's shadow, with a linear falloff where Material's is a blur.
On the Reply study's compose button -- a 56dp circle, the largest elevated
surface in the gallery -- that reads as a grey box around the disc, because the
rings follow the surface's bounding geometry and the accumulated alpha is high
enough to see. Calibrated per ring against the reference:

    band   reference   one alpha for all   these alphas
       1       0.071               0.148          0.071
       2       0.035               0.077          0.035
       3       0.020               0.039          0.020
       4       0.008               0.039          0.008

THE CLOSE. ContainerTransformTransition used its `closing` flag for one thing:
picking a mirrored curve. Everything else -- the geometry, the scrim, the
colour, the crossfade -- played the OPENING animation regardless of direction,
and the origin was looked up on the source form, which on the way back is the
page being left rather than the page being returned to. So it found nothing,
fell through to its no-origin guess, and grew the page out of the middle of the
screen a second time instead of folding it back into the button.

Now the direction is carried through properly: the anchor is found on whichever
page is NOT travelling, the buffers swap roles, the geometry runs backwards,
the colours cross the other way, and the scrim lifts smoothly across the run
in proportion to what is left rather than mirroring the opening's fifths --
mirroring held it at full black through the middle and dropped it in one step.

The mirrored curve is gone with it: 1 - curve(elapsed) already IS the mirrored
easing, so selecting a mirrored curve as well gave curve(1 - elapsed), which is
a different motion.

A pop is now MEASURED. Every step in the suite was an arrival, so a back
transition could be completely wrong with every number still green -- which is
exactly what happened. The new compose_back step scored 96.90% worst and 29.68%
mean on the code as it stood; it is 13.13% and 5.26% now.

Subject: [PATCH 168/333] flutter-runtime: let the widget walkers see through
 layout wrappers

A button consumes its content rather than mounting it, so it walks down to the
Text or Icon it can actually render. That walk stops at any wrapper it cannot
open, and it could open exactly one of them -- Tooltip. Padding, Center, Align,
SizedBox, Container and Expanded were all opaque to it, so a button whose label
sat inside any of them rendered NO label at all.

This is not a corner case. Shrine's login buttons are written the ordinary way,
`child: Padding(child: Text(...))`, and both rendered as blank shapes: the row
that should read CANCEL and NEXT was a small pink blob. Reply's compose screen
lost a whole row the same way -- its sender address is a PopupMenuButton whose
child is a Padding around a Row, so the account line was simply absent.

The runtime was saying so on every build: "child Padding is neither a Text nor
an Icon and could not be resolved to one; the button renders no label",
repeated for ElevatedButton, TextButton, IconButton and PopupMenuButton. Those
warnings are now gone -- the count in a full sweep of the gallery is zero.

Implemented by having those widgets declare HasChild, which is what the walk
already uses; each of them already exposed getChild(). Nothing else changes:
the elements that mount these widgets keep laying their child out themselves,
and the two render elements that cast their own widget to HasChild are
unaffected.

/shrine goes 2.68% -> 2.87% wrong pixels, and that is the metric being wrong
rather than the screen: rendering two buttons that were previously absent adds
pixels, and they are still mispositioned (the OverflowBar ignores its end
alignment) and CANCEL takes the wrong colour. Both are now visible problems
with visible buttons, which is the better place to be.

Subject: [PATCH 169/333] flutter-runtime: a text field keeps its decoration
 when it has focus

A Codename One theme gives a text field one border unselected and a different
one -- here, none -- selected. That is a reasonable default for a native-looking
field and wrong for this one: a reference text field keeps its decoration
whether it has focus or not, and only the caret and the highlight colour
change. We set a border explicitly only when the decoration names one, so
everywhere the border came from the theme, the focused field simply lost it.

What that looks like in use is worse than a missing outline: the box appears to
belong to whichever field is NOT being used, and it jumps to another field as
you touch things. Measured on Shrine's login screen, the outline's top and
bottom edges:

    on arrival           y = 1191, 1363      (the password field only)
    after tapping into
    the password field   y =  979, 1151      (the username field only)

Both fields now keep their outline, and tapping between them changes nothing:
four edges, at 979, 1151, 1191 and 1363, before and after.

/shrine goes 2.87% -> 3.17% wrong pixels. As with the buttons, that is the
metric rather than the screen: a box that was missing is now drawn, and its
corner radius and colour do not yet match -- Shrine's fields are beveled and
ours are rounded. A wrong-looking box in the right place is a smaller problem
than no box at all, and a visible one.

Subject: [PATCH 170/333] flutter-runtime: give IgnorePointer its one job, and
 end a vertical drag

A screen you can enter and cannot leave, found by using the app. Both of the
ways out of the gallery's splash page were dead.

IGNOREPOINTER IGNORED NOTHING. It was a structural pass-through: it rendered
its child and left that child fully live. The widget exists for exactly one
reason -- so that something ABOVE it receives a touch landing on top of its
child -- and with the child still answering, the handler above never runs. The
splash slides the home page down, leaves a strip of it showing, and wraps that
strip in an IgnorePointer inside a detector whose tap dismisses the splash. The
strip's own rows took the tap instead, so the dismiss never fired.

Codename One's hit test walks UP from the component it lands on for as long as
each one ignores pointer events, so the flag has to reach the whole subtree
rather than its root: a touch landing on a nested child would stop there.

ONVERTICALDRAGEND WAS NEVER INVOKED. The callback was stored and called from
nowhere in the runtime, so every flick gesture in the gallery did nothing. That
is the splash's second exit -- an upward flick on the same strip, which calls
reverse() directly -- and it is also how the splash is meant to be ENTERED.
Velocity is measured over the whole press rather than the last few moves, which
understates a flick that started slowly: that misses a gesture rather than
inventing one, and every caller compares against a threshold.

Deliberately NOT fixed here: Notification.dispatch() is still a no-op, so the
splash cannot be opened by its own gesture even now. Wiring it needs the
listener's type, and NotificationListener erases T -- delivering
notifications without a type token would hand every ScrollNotification to a
listener waiting for something else, so merely scrolling the gallery home would
open the splash. That wants a type token from the transpiler, not a guess in
the runtime.

Subject: [PATCH 171/333] Keep the transcode mojo's sources ASCII

Eight em dashes had crept into the javadoc of a file this branch adds to the
Maven plugin. Java sources here are ASCII only -- the toolchains that compile
this tree read them as ASCII, and a single non-ASCII byte fails the build with
"unmappable character for encoding ASCII" in a file nobody was editing.

Replaced with the ASCII double dash the rest of the tree uses. No behaviour
change; the plugin still builds.
