fix: Dispose codec after completing frame creation (#159945)
ref https://github.com/flutter/flutter/issues/93404,
[comment](https://github.com/flutter/flutter/issues/93404#issuecomment-2525453113)
and
[comment](https://github.com/flutter/flutter/issues/93404#issuecomment-2547622795).

Added a process to call `ui.Codec`'s `dispose`.
With this change,
[HtmlBlobCodec](8e0993eda8/engine/src/flutter/lib/web_ui/lib/src/engine/html_image_element_codec.dart (L100))'s
dispose will be called in Safari when using CanvasKit, and
`revokeObjectURL` will be executed as expected.

If this fix looks good, I will open the
https://github.com/flutter/flutter/pull/161481 to remove the
`AlearmClock` from the `BrowserImageDecoder`.

Fix Linux keyboard support for AltGr (#162495)
This was previously connected to right alt, which was confusing the
keyboard handling code into generating up events for this key when it
didn't match the expected values. This key is also configurable, and
only defaults to right alt in Ubuntu/GNOME.

[Android] add runtime flag to determine if HCPP is supported. (#163004)
Developers will need to _conditionally_ use HCPP (or the framework will
need to handle it automatically). This requires the ability to query at
runtime whether HCPP mode is enabled + supported.

Add a message channel to do so, and add the usage of this to the
android_engine_test. Does not yet add any automatic selection.

Return more eagerly when toggling service extensions (#162774)
Fixes https://github.com/flutter/devtools/issues/8497

When handling requests to enable or disable service extensions, we
currently wait until the next frame is rendered before responding to the
request. If the app is hidden this will not happen until the app is
unhidden, or a frame is scheduled for some other reason.

This fix does not await the next frame before responding - which I think
is reasonable - but feel free to push back if there is a reason to not
do it that way.

Updated tests to expect the response before actually rendering the next
frame.

Fix Status Bar Icon Brightness (#162297)
On Android devices, the statusBar is now by default transparent starting
android API 35
[here](https://developer.android.com/develop/ui/views/layout/edge-to-edge#:~:text=system%20bars%20transparent)
(due to automatic opt-in to edge to edge mode
[here](https://developer.android.com/develop/ui/views/layout/edge-to-edge#:~:text=Important%3A%20Edge%2Dto%2Dedge%20is%20enforced%20on%20Android%2015%20(API%20level%2035)%20and%20higher%20once%20your%20app%20targets%20SDK%2035.%20If%20your%20app%20is%20not%20already%20edge%2Dto%2Dedge%2C%20portions%20of%20your%20app%20may%20be%20obscured%20and%20you%20must%20handle%20insets.%20Depending%20on%20the%20app%2C%20this%20work%20may%20or%20may%20not%20be%20significant.)),
which is making the statusBar icons difficult to see. We decided to make
the change in Cupertino/Material layer as opposed to the embedder layer
becasue we cannot make assumptions on the defaults when we don't know
what kind of Widgets the Flutter dev will be using.

In MaterialApp, the `statusBarIconBrightness` is made to be dark because
the system's brightness (dark mode or light mode) **does not affect**
the brightness of the default app. This means when I turn on dark mode
on my phone, the app does not use a dark theme—it uses the same light
theme.

In CupertinoApp, the `statusBarIconBrightness` is made to be opposite of
the system's brightness (dark mode or light mode) because the system
**does affect** the brightness of the default app. The system and the
default app have the same brightness. This means when I turn on dark
mode on my phone, the app also uses a dark theme.

Fixes #160305

Directional focus edge traversal behavior. (#161285)
Fixes: #160843 

This PR adds edge behavior feature for traversing focus using arrow
keys. This allows cycling through the focus within the `FocusScope` in a
closed loop using the arrow keys. Which may be needed by TV application
developers.

Additionally, as in case #160843, `TraversalEdgeBehavior.parentScope`
can be used to allow nested Navigators to traverse focus beyond the
Navigator using arrow keys.

```dart
MaterialApp(
  home: Column(
    children: <Widget>[
      makeFocus(0),
      Navigator(
        onGenerateRoute: (RouteSettings settings) {
          return MaterialPageRoute<void>(
            traversalDirectionedEdgeBehavior: TraversalEdgeBehavior.parentScope,
            builder: (BuildContext context) {
              return Column(
                children: <Widget>[
                  makeFocus(1),
                  makeFocus(2),
                ],
              );
            },
          );
        },
      ),
      makeFocus(3),
    ],
  ),
);
```

Adjustments to FocusHighlightMode handling (#162417)
Fixes https://github.com/flutter/flutter/issues/158527

Adjustments:
* Using the mouse/trackpad does no longer change `FocusHighlightMode`s
(this matches observed behavior on Android)
* Changing focus via a11y on the web forces `FocusHighlightModes.touch`,
which hides the visual input focus indication from non-Textfields. The
reason here is in order to give something input focus on the web it also
has to have a11y focus, which is indicated separately.

Remove outdated ignores (#162773)
Powered by the new and amazing `unnecessary_ignore` lint.

We're not enabling this lint by default because being able to
temporarily use ignores that don't ignore anything is a powerful tool to
enable migrations. We should turn this lint on locally periodically,
though, and clean up all outdated ignores.

Fix: Ensure CupertinoAlertDialog divider spans full width and resolve (#161490)
Fix: Ensure CupertinoAlertDialog divider spans full width and resolves
divider color (#158522)

The `_Divider` in CupertinoAlertDialog did not span the full width and
the `dividerColor` was not resolved correctly. This fix uses a
`SizedBox` with `double.infinity` as the width for the divider and
ensures that the `dividerColor` is properly applied.

Fixes #158522

Update code comments for navigation_bar.dart (#162596)

### Comments error:
```
class NavigationDestination extends StatelessWidget {
...

  /// The text label that appears below the icon of this
  /// [NavigationDestination].
  ///
  /// The accompanying [Text] widget will use
  /// [NavigationBarThemeData.labelTextStyle]. If this are null, the default
  /// text style would use [TextTheme.labelSmall] with [ColorScheme.onSurface].
  final String label;

...
}
```

`If this are null, the default text style would use
[TextTheme.labelSmall]` is wrong. Actually, This is right in material2,
but wrong in material3. I have dived into `_NavigationBarDefaultsM3`, I
found this:
```
class _NavigationBarDefaultsM3 extends NavigationBarThemeData {
...

@override
  MaterialStateProperty<TextStyle?>? get labelTextStyle {
    return MaterialStateProperty.resolveWith((Set<MaterialState> states) {
    final TextStyle style = _textTheme.labelMedium!;
      return style.apply(
        color: states.contains(MaterialState.disabled)
          ? _colors.onSurfaceVariant.withOpacity(0.38)
          : states.contains(MaterialState.selected)
            ? _colors.onSurface
            : _colors.onSurfaceVariant
      );
    });
  }

...
}
```
**The default text style would use [TextTheme.labelMedium] in
Material3.**

[web] Only create one <style> for SelectableRegion (#161682)
We used to create and insert a new `<style>` element for each
`SelectableRegion` widget. That's unnecessary. All we need is one
`<style>` element that contains the style sheets that we want to apply.

Most of this PR is re-working the tests to be able to check that the
issue is actually fixed.

Make CupertinoSheetRoute usable with Cupertino(Sliver)NavigationBar (#162181)
Working on the cupertino nav bars recently gave me some context on those
widgets, so when I saw this
[comment](https://github.com/flutter/flutter/pull/157568#issuecomment-2590955571)
I was inspired to add a fix :)

Thanks @MaherSafadii for [starting the
exploration](https://github.com/flutter/flutter/pull/157568#issuecomment-2592535332)
and also for the very helpful
[screenshots](https://github.com/flutter/flutter/issues/162021#issuecomment-2608430023).

Removes the following when
CupertinoNavigationBar/CupertinoSliverNavigationBar is used in a
CupertinoSheetRoute:
- Unneeded back button
- Superfluous top padding in CupertinoNavigationBar
- Full page route transitions

Support ignoring pointer events on tooltip overlay (#142465) (#161363)
As #142465 states, tooltips often interrupt widget interactivity by not
allowing events to pass through to the Tooltip child, which is
especially poor UX when hovering interact-able widgets on web when the
mouse happens to land on the tooltip.

I've gone with defaulting ignorePointer to true when a simple message is
supplied, since there won't ever be anything interact-able on the
Tooltip, and defaulting to false when richMessage is supplied, so it
doesn't break anyone's code that has interact-able widgets in the
Tooltip.

Adjust padding for Cupertino sheet content (#162481)
Fixes #162215 and partially supports #162181.

The Cupertino sheet had two issues layout: It still had MediaQuery
padding at the top of the screen as if there was safe area content to
avoid and some of the sheet was permanently offscreen. This caused a
FloatingActionButton to be clipped, but if you put a scrolling widget in
the sheet with text at the very bottom, it was impossible to scroll the
text into view. This PR removes the top padding, and changes the bottom
padding to equal the amount offscreen.

Implement RawMenuAnchor (#158255)
This PR adds a `RawMenuAnchor()` widget to widgets.dart. The purpose of
this widget is to provide a menu primitive for the Material and
Cupertino libraries (and others) to build upon. Additionally, this PR
makes MenuController an inherited widget to simplify nested access to
the menu (e.g. if you want to launch a context menu from a deeply-nested
widget).

This PR:
* Centralizes core menu logic to a private class,` _RawMenuAnchor()`, 
  * Provides the internals for interacting with menus:
    * TapRegion interop
    * DismissMenuAction handler
    * Close on scroll/resize
    * Focus traversal information, if applicable
* Subclasses override `_open`, `_close`, `_isOpen`, `_buildAnchor`, and
`_menuScopeNode`
* State is accessible by descendents via
`MenuController.maybeOf(context)._anchor`
* Adds 2 public constructors, backed by a `_RawMenuAnchor()` that
contains shared logic.
  * `RawMenuAnchor()`
    * Users build the overlay from scratch.
* Provides anchor/overlay position information and TapRegionGroupId to
builder
    * Does not provide FocusScope management. 
  * `RawMenuAnchorGroup()`
    * A primitive for menus that do not have overlays (menu bars). 
* This was previously called RawMenuAnchor.node(), but @dkwingsmt made a
good case for splitting out the constructor.

<s>Documentation examples have been added, and can be viewed at
https://menu-anchor.web.app/</s>

List which issues are fixed by this PR.
https://github.com/flutter/flutter/pull/143712

Some issues that need to be addressed:

Semantics:
<img width="1027" alt="image"
src="https://github.com/user-attachments/assets/d69661c9-8435-4d9c-b200-474968cb57eb">
I'm basing the menu semantics off of the comment
[here](ef3ca70db2/lib/web_ui/lib/src/engine/semantics/semantics.dart (L382)),
but I'm unsure whether the route should be given a name. There is no
menubar/menu/menuitem role in Flutter, so I'm assuming the menu should
be composed of nested dialogs

<s>Unlike the menubar pattern from
[W3C](https://www.w3.org/WAI/ARIA/apg/patterns/menubar/examples/menubar-navigation/),
the RawMenuAnchor

- does not close on tab/shift-tab. I left this behavior out of the menu
so that users could customize tab behavior, but I'm not opinionated
either way
- does not open on ArrowUp/ArrowDown, because this could interfere with
user focus behavior in unconventional menu setups (e.g. a vertical
menu).
- does not automatically focus the first item in a menu overlay when
activated via enter/spacebar, but does focus the first item when
horizontal traversal opens a submenu. Automatically focusing the first
item whenever an overlay opens interferes with hover traversal, and I
couldn't think of a good way to only focus the first item when an
overlay is triggered via enter/spacebar.
- doesn't focus disabled items (I wasn't sure how to address this
without editing MenuItemButton)

While it is possible to nest menus -- for example, a dropdown anchor
within a full-app context menu area -- nested menus behave as a single
group. I was considering adding an additional parameter that separates
nested root menus from their parents, and am interested to hear your
feedback.</s>

[Reland] Fix Tab linear and elastic animation blink (#162315) (#162450)
Relands https://github.com/flutter/flutter/pull/162315

Removed animated sheet golden tests as they're not consistent for long
animation tests. Rewritten the tests to be more precise using mock
canvas checks.

--- 

Fixes
[https://github.com/flutter/flutter/issues/162098](https://github.com/flutter/flutter/issues/162098)

### Description 

This PR fixes `Tab` linear and elastic animation blinks/flickers when
skipping multiple tabs. Previous attempt to fix elastic animation didn't
cover linear animation tests and didn't have enough number of tab items
which this PR fixes.

- Fixed Linear and elastic animation blink issue.
- Added tests for linear and elastic animation with various tab sizes
(LTR and RTL)
- Added tests for linear and elastic animation when skipping tabs (LTR
and RTL)

Add WidgetPreview and @Preview() annotation (#159219)
This is the initial work for the upcoming Widget Preview functionality.

The `WidgetPreview` class allows for users to specify overrides and
details to apply to its child `Widget`. Initially, this includes:

- Setting arbitrary width and height constraints to mimic changes in
device resolution
 - Custom text scaling factors

The `Preview` class is an annotation used to identify top-level, public
functions as widget previews

Fix Tab linear and elastic animation blink (#162315)
Fixes
[https://github.com/flutter/flutter/issues/162098](https://github.com/flutter/flutter/issues/162098)

### Description 

This PR fixes `Tab` linear and elastic animation blinks/flickers when
skipping multiple tabs. Previous attempt to fix elastic animation didn't
cover linear animation tests and didn't have enough number of tab items
which this PR fixes.

- Fixed Linear and elastic animation blink issue.
- Added tests for linear and elastic animation with various tab sizes
(LTR and RTL)
- Added tests for linear and elastic animation when skipping tabs (LTR
and RTL)

### Code Sample
