Fixed changing supportedLocales fails to update the locale (#178526)

Recompute the resolved locale in LocalizationsResolver.update(...) and
notify listeners
only when the resolved locale actually changes. Previously, updating
WidgetsApp.supportedLocales
did not always propagate to the app locale because the resolver did not
re-resolve and
notify listeners. This change fixes that bug and adds unit tests.

This change reverts the following previous change:
This is a reland of #177570, which was reverted in #178744 due to test
failures.

The original PR introduced `hitTestBehavior` to the semantics framework
but incorrectly applied `opaque` behavior to `ModalRoute`, which blocked
platform views from receiving pointer events.

Instead of making the entire modal opaque, we:
1. Keep `ModalRoute` without explicit `hitTestBehavior` (defaults to
`defer`)
2. Make only the dialog/sheet content opaque (blocks clicks to barrier)
3. Platform views remain clickable because they're outside the opaque
content boundary

Fixes #149001

Remove semantics geometry shortcircuit (#178680)
Fixes https://github.com/flutter/flutter/issues/173097

The semantics flush is ~200 μs slower with the shortcuircut removed +
#177477 (which reduces the time increase by ~ 100 μs, from 876 μs to 773
μs) I tried to introduce caching in [a different
patch](https://github.com/flutter/flutter/compare/master...LongCatIsLooong:semantics-geometry?expand=1)
but that patch is more risky and still needs a cleanup.

773 μs doesn't seem bad considering there were little to no geometry
updates between frames before the fix. Introducing cache currently only
improves `Semantics.ensureGeometry` by less than 100 μs and is much more
risky / harder to ensure the correctness.

Make a11y computeChildGeometry slightly faster (#177477)
This is not a fix for #166173, it's only a by-product. The fix will be
in separate PR, this includes the unrelated code changes to make that PR
smaller.

According to `bench_material3_semantics`, this reduces
`Semantics.ensureGeometry` by ~100 μs (321.6 μs -> 228.9 μs).

Remove the hack used to get the runtimeType without using an additional class in key.dart (#178219)
some context :
[#33297](https://github.com/dart-lang/sdk/issues/33297) suggested that
`Type literals should support generics` which means that this would
become a valid syntax `Type type = List<int>;`.
the hack used here directly references to that issue :
2981516d74/packages/flutter/lib/src/foundation/key.dart (L109-L120)
because something like :
```dart
Type type = List<int>;
typedef MakeNullable<T> = T?;
typedef TypeOf<T> = T;
```
was not a valid syntax at the time of writing `key.dart`
since that issue is closed and those are valid syntax now , it is safe
to remove this hack and use what @lrhn suggested in this
[comment](https://github.com/dart-lang/sdk/issues/33297#issuecomment-1108974509)
```dart
typedef TypeOf<T> = T;
```
in other words , before:
```dart
if (runtimeType == _TypeLiteral<ValueKey<T>>().type) {
}

class _TypeLiteral<T> {
  Type get type => T;
}
```
after:
```dart
if (runtimeType == _TypeOf<ValueKey<T>>) {
}

typedef TypeOf<T> = T;
```

Image GIF pausing (#176492)
Flutter needs a strong story around pausing animated GIFs because it
affects accessibility via
[MediaQueryData.disableAnimations](https://main-api.flutter.dev/flutter/widgets/MediaQueryData/disableAnimations.html).
See https://github.com/flutter/flutter/issues/175516.

### Today

Currently, it's possible to pause a gif using TickerProvider. However,
if paused on initial load, the first frame will never display, and I
believe that's a bug.

```dart
TickerMode(
  // Pauses the gif, but if set to false on first load, the first frame never loads.
  enabled: false,
  child: Image(image: myAnimatedGif),
),
```

Currently `disableAnimations` has no effect:

```dart
MediaQuery(
  // Currently has no effect on the Image, until this PR.
  data: MediaQueryData(disableAnimations: true),
  child: Image(image: myAnimatedGif),
),
```

### With this PR

* MediaQueryData.disableAnimations can be used to pause a gif in the
same way that TickerMode can be used today.
* If either MediaQuery.disableAnimations or TickerMode cause a gif to be
paused on first load, it will show its first frame before pausing. This
is potentially a breaking change.
  * The docs clearly explain this behavior and how to pause a gif.

Add focus support for CupertinoActionSheetAction #166398 (#167119)
<!--
Thanks for filing a pull request!
Reviewers are typically assigned within a week of filing a request.

### This PR fixes #166398
- Adds focus support for `CupertinoActionSheetAction`. This makes it
work with keyboard shortcuts
- Creates new widget, `CupertinoTraversalGroup` that applies a Cupertino
style focus border around its child when any of its descendant has focus
- Employs `CupertinoTraversalGroup` in `CupertinoActionSheet`

How the new implementation looks and behaves:

Listen to text spacing overrides on the web (#178081)
Original PR/Discussion: https://github.com/flutter/flutter/pull/172915

# Framework:
* `EditableText`/`SelectableText`, applies
`lineHeightScaleFactorOverride`, `wordSpacingOverride`, and
`letterSpacingOverride` to it's `TextStyle` similarly to how we already
do for bold platform overrides. Note `SelectableText` is built on
`EditableText` so it also applies these overrides.
* `Text`, applies `lineHeightScaleFactorOverride`,
`wordSpacingOverride`, and `letterSpacingOverride` to it's `TextStyle`
similarly to how we already do for bold platform overrides.
* Exposes line height override through
`MediaQueryData.lineHeightScaleFactorOverride` and
`maybeLineHeightScaleFactorOverrideOf(context)`.
* Exposes letter spacing override through
`MediaQueryData.letterSpacingOverride` and
`maybeLetterSpacingOverrideOf(context)`.
* Exposes word spacing override through
`MediaQueryData.wordSpacingOverride` and
`maybeWordSpacingOverrideOf(context)`.
* Exposes paragraph spacing override through
`MediaQueryData.paragraphSpacingOverride` and
`maybeParagraphSpacingOverrideOf(context)`.
* `MediaQuery.applyTextStyleOverrides()` \
`MediaQueryData.applyTextStyleOverrides()` to be able to reset/override
the text spacing settings on `MediaQueryData`.

# Engine:
* Introduces new members on `PlatformDispatcher` API that hold the text
spacing properties that are overridden on the web.
* We provide the `lineHeightScaleFactorOverride`,
`letterSpacingOverride`, `wordSpacingOverride`, and
`paragraphSpacingOverride` on the web by attaching a `ResizeObserver` to
an off-screen hidden element, when its size changes we capture its text
spacing CSS properties, and notify the framework through
`onMetricsChanged`.

Fixes #142712

Fix VoiceOver does not announce state of ButtonSegment (#175635)
- Fix https://github.com/flutter/flutter/issues/146987
- As explained at
https://github.com/flutter/flutter/issues/146987#issuecomment-3294737075:
this PR proposes _replacing_ `checked` with `selected` here:
 

f4de70c647/packages/flutter/lib/src/material/segmented_button.dart (L634)
 
Then VoiceOver can indicate when the button segment is selected. It's
_replacing_ action but not _adding_ because _adding_ (keep both
`checked` and `selected`) will cause the button to be read with both
checked and selected states with Android TalkBack reader that may cause
confusion to users (watch demo videos). I also did test with iOS
segmented control (storyboard) and Android Jetpack Compose to compare:
on these native platforms, it announces `selected` state (watch demo
videos).

Add DeviceOrientationBuilder widget by MediaQuery orientation (#177437)
<!--

Reviewers are typically assigned within a week of filing a request.

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

 ## Issues Fixed

  Fixes https://github.com/flutter/flutter/issues/177435

On foldable Android devices, `OrientationBuilder` and
`MediaQuery.orientation` can report different orientations.
`OrientationBuilder` calculates orientation from layout constraints
(width vs height),
while `MediaQuery` reports the actual device orientation from the
platform. This PR adds a new `DeviceOrientationBuilder` widget that uses
`MediaQuery.orientationOf()` to ensure consistency with the
  device's actual orientation.

  ## Breaking Changes

No breaking changes. This PR does not modify any existing code in the
flutter/tests repo or require a migration guide.

[Android] Encode the original pointer count in messages that represent Android touch events (#178015)
Android touch events include updates to multiple pointers, but each
pointer data message sent from the embedder to the framework represents
a single pointer. So the Android embedder will send multiple messages
for each touch event, and the framework's AndroidViewController will
reassemble the messages and forward the resulting event to the platform
view.

The AndroidViewController tracks the number of active pointers in its
own local state. If that state is out of sync with the event handled by
the Android embedder, then the AndroidViewController may send duplicate
events to the platform view.

This PR encodes the Android touch event's pointer count in the messages
sent to the framework. This allows the AndroidViewController to reliably
determine whether it has received all of the pointer messages that
originated from an event.

Fix text input actions in DropdownMenu. (#177313)
Fixes https://github.com/flutter/flutter/issues/177009

### Description

- Moves `MenuButton` submit logic from `onEditingComplete` to
`onSubmitted` to allow `TextField` to handle the `textInputAction` logic
- Wraps each item into `ExcludeFocus` to enable proper
`TextInputAction.previous` handling. If we don't wrap each child in
`ExcludeFocus`, then focus will be moved to one of them, which is not
the expected behavior for `TextInputAction.previous`.

                  DropdownMenuEntry(value: 'green', label: 'green'),
                  DropdownMenuEntry(value: 'blue', label: 'blue'),
                ],
              ),
              TextField(
                focusNode: _nextFocusNode,

          ),
        ),
      ),
    );
  }
}
```

</details>

There is still one behavior I would like to discuss. When the
`showTrailingIcon: true` and `textInputAction: TextInputAction.previous`
are used, the focus moves not to the previous field but to the
`IconButton`. If we wrap the `IconButton` with `ExcludeFocus`, then this
is fixed, but I am not sure whether this is the correct way to proceed.

Allow label to be used to compute InputDecorator Intrinsic width (#178101)
## Description

This PR adds `InputDecorator.maintainLabelSize` (similar to
`InputDecorator.maintainHintSize`) to allow the label to be used in the
intrinsic width calculation (if could be used for the intrinsic height
calculation later if needed).

I opted for this flag (and defaulting to false) because changing the
default calculation would probably break various usages.
See
https://github.com/flutter/flutter/issues/178099#issuecomment-3496116095
for why this change will be helpful to simplify and fix DropdownMenu
implementation.


## Before

The label might be cut off:

src="https://github.com/user-attachments/assets/61d9f817-5c58-43f9-9307-976f9c124ec7"
/>

## After

The label is entirely visible because it is part of the intrinsic width
calculation:

Remove WindowingOwner.hasTopLevelWindows (#178033)
This function doesn't seem to serve any purpose.
Top level is not a term we are currently using in the multi window code.
If we want to track if we have open windows, this can be done in the
Flutter framework - it doesn't need to be done at the platform level.

Fix ReorderableList items jumping when drag direction reverses mid-animation (#173241)
When rapidly dragging items in a ReorderableList before animations
complete, items would jump to their expected positions rather than
smoothly transitioning.

## Problem

<p align="center">
<img
src="https://github.com/user-attachments/assets/0efb250c-2960-4942-959f-59eccc20cefb"
alt="demo2" width="250">
</p>

The issue occurs when a reorder animation is interrupted by starting a
new drag operation. The interrupted animation would reset to the
starting position of the original animation rather than capturing the
current animated position, causing a visual jump.

## Solution

This PR fixes the issue by:
1. Storing the previous target offset before updating to a new target
2. When an animation is interrupted, calculating the actual current
position based on the animation's progress
3. Using this calculated position as the new starting point for the next
animation

<p align="center">
<img
src="https://github.com/user-attachments/assets/c24e4834-1c6b-41c1-8f44-17b4c79e0993"
alt="demo2" width="250">
</p>

This PR is part of a series of `ReorderableList` enhancements I've
developed for [TimeFinder](https://timefinder.app):
- #172740
- #172380
- #172739
- #172738

Fixes #173243

## Code Changes

```dart
// Before
_startOffset = offset;

// After  
final double currentAnimValue = Curves.easeInOut.transform(_offsetAnimation\!.value);
final Offset currentPosition = Offset.lerp(_startOffset, previousTarget, currentAnimValue)\!;
_startOffset = currentPosition;
```

This ensures smooth transitions without visual jumping, making rapid
reordering gestures feel more responsive and natural.
