Do not wait until dispose before removing replaced/popped page (#182315)
Regression was introduced in [Cleans up navigator pop and remove
logic](https://github.com/flutter/flutter/pull/175612/changes#top).

That PR moved the `onDidRemovePage` call to `_flushHistoryUpdates` in
phase `_RouteLifecycle.dispose`. But waiting until `dispose` causes
potential problems if the widget is rebuilt in a phase preceding that
(but after `pop` or `pushReplacement` has been called). So the outdated
page remains in the pages list even after it has been marked for
removal.

This is causing the page to be pushed again before it is finally
removed, causing the flicker.

feat: add routes support in TestWidgetsApp (#181695)
Feat: Add routes and transitionBuilder support in TestWidgetsApp

part of: https://github.com/flutter/flutter/issues/177415

As many test might need navigation with routes, we need to expose route
from WidgetApp to TestWidgetsApp.

[Web] Fix IME and selection by syncing more text styles (#180436)
fix https://github.com/flutter/flutter/issues/161592

The current implementation does not fully reflect
[letter-spacing](https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Properties/letter-spacing),
[word-spacing](https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Properties/word-spacing),
and
[line-height](https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Properties/line-height)
in the DOM. 0bc99f8c4f70973a1877c88ca35804e9bc5fabcf
And the current implementation generates an DomHTMLTextAreaElement every
time the `enabled`. Therefore, it reapplies the
[scrollTop](https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollTop)
value that the Element had been holding internally.

remove MaterialApp import from raw_radio_test.dart (#181721)
<!--
Thanks for filing a pull request!
Reviewers are typically assigned within a week of filing a request.
To learn more about code review, see our documentation on Tree Hygiene:
https://github.com/flutter/flutter/blob/main/docs/contributing/Tree-hygiene.md
-->

The RawRadio widget and its associated tests are part of the Widgets
layer, not the Material layer. By replacing the broad material.dart
import with specific imports (foundation.dart, semantics.dart, and
widgets.dart), we ensure better architectural layering and prevent the
Widgets layer from accidentally depending on Material components.

This is a non-breaking change that purely cleans up imports in a test
file.

[web] Fix scroll event bubbling in iframes (#179703)
Fixes scroll event bubbling when Flutter web is embedded in an
iframe(#156985).

When a scrollable handles a wheel event, it now calls
respond(allowPlatformDefault: false) to signal the engine.

In iframe mode, the engine always calls preventDefault() to block native
scroll chaining, then uses postMessage to explicitly scroll the parent
page only when all scrollables are at boundary

[Material] Remove Material import from backdrop_filter_test.dart widget tests (#181386)
<!--
Thanks for filing a pull request!
Reviewers are typically assigned within a week of filing a request.

https://github.com/flutter/flutter/blob/main/docs/contributing/Tree-hygiene.md
-->

Migrate backdrop_filter_test.dart to use only widget imports following
issue #177415. Split the tests into two files:

- Widgets tests
(packages/flutter/test/widgets/backdrop_filter_test.dart):
  * Removed Material import, now uses widgets-only
  * Replaced MaterialApp + Scaffold with Directionality wrapper
  * Replaced Colors.black.withAlpha(40) with Color(0x28000000)
  * Kept 2 tests that validate BackdropFilter key behavior

- Material tests
(packages/flutter/test/material/backdrop_filter_test.dart):
  * Moved 4 Material-specific golden file tests (M2/M3 comparisons)
* These tests require Material theming to validate rendering differences

- Updated dev/bots/check_tests_cross_imports.dart to remove
backdrop_filter_test.dart

This approach keeps Material-specific tests in the material directory
while enabling the simple widget tests to pass without Material
dependencies.

Move CheckedModeBanner tests to material and remove Material import from widgets banner_test (#181261)
<!--

Move Material-specific Banner tests to the appropriate test file:
- `Banner widget in MaterialApp` test moved to material/banner_test.dart
- `CheckedModeBanner does not crash at zero area` test moved to
material/banner_test.dart

Remove Material import from `widgets/banner_test.dart` since all
remaining tests only use widgets-level BannerPainter and BannerLocation
APIs.

Update cross imports list to remove banner_test.dart from
knownWidgetsCrossImports.

All tests pass and no formatting issues detected.

Propagates Overlay's MediaQueryData to OverlayPortal child (#181579)
Widgets like Scaffold strip MediaQueryData causing widgets rendered in
the Overlay to be obscured, e.g., by the software keyboard.

[Related Issue -
157664](https://github.com/flutter/flutter/issues/157664)

This does not directly fix these two issues but appears to be an
underlying issue with both which merited this being a separate PR. I
have a separate fix for the MenuAnchor that I will supply in a follow up
PR.

Fix decorated box (#179802)
Fix #179801

`RenderSliver.getMaxPaintRect` was moved up to `RenderSliver` as it is
also needed for PR #179003, the logic was therefore duplicated here.

(The widget labeled `A SliverToBoxAdapter` is actually a
`PinnedHeaderSliver`)

Remove Material library dependency from expansible_test.dart (#181657)
This PR removes the unnecessary dependency on the Material library from
expansible_test.dart by replacing `MaterialApp` with `WidgetsApp`.

Part of #177415

### Changes

1. **Import change**: Replaced `package:flutter/material.dart` with
`package:flutter/widgets.dart`

2. **Widget setup**: Changed from `MaterialApp(home: ...)` to
`TestWidgetsApp(home: ...)`
- `WidgetsApp` requires either `builder`, `onGenerateRoute`, or
`pageRouteBuilder` to be provided
If neither builder nor onGenerateRoute are provided, the
pageRouteBuilder must be specified so that the default handler will know
what kind of PageRoute transition to build.

3. **Updated position assertions**: Since `WidgetsApp` with `builder`
doesn't include the default scaffold/status bar padding that
`MaterialApp` with `home` provides, the expected y-coordinate values
were adjusted by -34 pixels:
   - `90.08984375` → `56.08984375`
   - `98.0` → `64.0`
   - `80.91015625` → `46.91015625`
   - `48.0` → `14.0`

Reduce reliance on Material in page_transitions_test.dart (#181467)
This PR reduces the reliance on Material in page_transitions_test.dart
but does not entirely remove it.

1) Moves a test for persistent bottom sheet to the right file
2) Fixes a use of `sync*` (not sure why this is not caught by
dev/bots/analyze.dart, that _does_ check for `sync*` cc @Piinks )
3) Replaces some easy usages of Material widgets with its widget
counterparts.

The only thing that I did not yet fix is replacing `MaterialApp` in this
file. That probably needs @victorsanni 's work on page transitions to be
addressed first?

Remove material from slivers_appbar_floating_pinned_test.dart + slivers_appbar_stretch_test.dart + sliver_persistent_header_test.dart + slivers_appbar_floating_test.dart (#181469)
This PR cleans up material imports in
slivers_appbar_floating_pinned_test.dart (this was actually testing
`SliverPinnedHeader` ?) and moves tests from
`test/widgets/slivers_appbar_stretch_test.dart` to the right test file
under the Material tests.

A bunch of tests have been moved 1 to 1 to their new destination. Some
test code was deduplicated and a bunch of tests had their names fixed.
Except for one test that needed an updated `find` expression, due to a
change in one of the `SliverPersistentHeaderDelegate`s, nothing was
semantically changed in the tests that were updated in this PR.

Enhance error handling of WidgetsBindingObserver callbacks (#181174)
<!--
Thanks for filing a pull request!
Reviewers are typically assigned within a week of filing a request.
To learn more about code review, see our documentation on Tree Hygiene:
https://github.com/flutter/flutter/blob/main/docs/contributing/Tree-hygiene.md
-->

Wraps all 16 WidgetsBindingObserver callback invocations in try-catch
blocks to prevent silent failures and ensure all observers are notified
even when one throws an exception.

Previously, exceptions in observer callbacks would either:
- Be silently discarded (method channel handlers)
- Prevent subsequent observers from being notified

Now, exceptions are properly reported via FlutterError.reportError and
all observers continue to receive notifications.

Fixes flutter/flutter#180434

Add TestWidgetsApp utility and refactor widget tests to use WidgetsApp (#180456)
This PR introduces a TestWidgetsApp utility class that provides a
minimal WidgetsApp wrapper for widget tests, replacing direct usage of
Directionality widgets.

## Changes
- test_widgets_app.dart - A reusable TestWidgetsApp widget that wraps
WidgetsApp with a builder pattern, providing Directionality, MediaQuery,
and other app-level widgets that WidgetsApp provides.
- gesture_detector_test.dart - Replaced 9 Directionality usages
- mouse_region_test.dart - Replaced 13 Directionality usages
- opacity_test.dart - Replaced 2 Directionality usages
- slivers_evil_test.dart - Replaced 3 Directionality usages and removed
redundant MediaQuery wrappers

## Note
- This PR updates golden test baselines for opacity_test.dart.

Deprecate onReorder callback (#178242)
This pull request deprecates the old `onReorder` callback of
`ReorderableList` / `SliverReorderableList` / `ReorderableListView`, in
favor of a new callback, `onReorderItem`, that does the index correction
as mentioned in the docs at
https://api.flutter.dev/flutter/widgets/ReorderCallback.html

I added tests to ensure that the old callback is preferred when both are
provided and tests that assert that the new callback does the index
correction correctly. I also noticed that some tests used empty
callbacks for `onReorder`, those have been updated to use wildcards in a
consistent manner.

I did not opt into making a design doc, since the change itself is very
small, that will also be apparent in the migration guide that I am going
to write.

Send statusBarTouch events via dedicated messages (#179643)
Instead of using fake touch events. 

Before this patch `FlutterViewController` sends two fake touch events
(down and up), at `(0, 0)` to the framework to signal that the status
bar is tapped on iOS. The scaffold widget and the cupertino page
scaffold widget set up gesture detectors to listen for these fake taps,
and scroll the "primary" scrollable container to the top in response.

This messaging mechanism is sometimes ambiguous, as the framework may
interpret that as a pair of regular pointer tap events (for instance in
#177992 the modal barrier claims the tap gesture and as a result the
modal barrier is dismissed by the fake touch events). This PR changes
that to communicate the status bar tap event via a new system channel,
and dispatch the events via `WidgetsBindingObserver`s in the framework.

See also
https://github.com/flutter/flutter/issues/177992#issuecomment-3499913265

Fixes #177992, fixes #175606

It appears that UIKit also has access to the coordinates of the touch
events to determine which scrollable view(s?) to dispatch the scroll to
top event to.
```objc
  * frame #0: 0x00000001032f6520 UIPlayground.debug.dylib`MyScrollViewController.scrollViewShouldScrollToTop(scrollView=0x0000000106014800) at UIScrollView.swift:13:3
    frame #2: 0x00000001867c9300 UIKitCore`-[UIScrollView _scrollToTopIfPossible:] + 316
    frame #3: 0x00000001867c9604 UIKitCore`-[UIScrollView _scrollToTopFromTouchAtScreenLocation:resultHandler:] + 40
    frame #4: 0x0000000186299bbc UIKitCore`__71-[UIWindow _scrollToTopViewsUnderScreenPointIfNecessary:resultHandler:]_block_invoke.358 + 168
    frame #5: 0x000000018629981c UIKitCore`-[UIWindow _scrollToTopViewsUnderScreenPointIfNecessary:resultHandler:] + 1212

    frame #7: 0x000000018581eb60 UIKitCore`-[UIStatusBarManager handleTapAction:] + 60
```
Unfortunately that information is not available to user application. The
iOS accessibility bridge currently does create dummy UIScrollViews for
each scrollable in the accessibility tree so may be we can take
advantage of that in the future.

Remove unnecessary Material import from sliver_visibility_test (#181248)
<!--
Thanks for filing a pull request!

https://github.com/flutter/flutter/blob/main/docs/contributing/Tree-hygiene.md

Remove the Material import from sliver_visibility_test.dart since it's
only testing SliverVisibility, a widgets-level component. The test
doesn't need Material-specific functionality - it only uses
DefaultWidgetsLocalizations.delegate which provides sufficient
localization support.

Changes:
- Replaced `import 'package:flutter/material.dart'` with `import
'package:flutter/widgets.dart'`
- Removed `DefaultMaterialLocalizations.delegate` from the localizations
delegates list

This helps with the decoupling of Material and Cupertino from the core
framework.

[Android] Add display corner radii support. (#179219)
Closes https://github.com/flutter/flutter/issues/97349
Unblocks https://github.com/flutter/flutter/issues/178463

### Description

This PR focuses only on the Android side.

As was discussed in https://github.com/flutter/flutter/issues/97349, the
iOS API for getting display corner radii is private. The only safe way
to get the radii values is to generate a lookup table ahead and use its
values at runtime. I would be happy to work on the iOS implementation in
a separate PR after this lands.

- Adds `displayCornerRadii` in the physical pixels to the engine's
window metrics
- Adds `displayCornerRadii` support on the Android API 31+
- Adds `displayCornerRadii` in the logical pixels to the `MediaQuery`
- Adds and updates tests
