Fix DecoratedSliver sample to avoid antialiasing gap (#179848)
## Description

The DecoratedSliver sample was showing an antialiasing gap between two
adjacent slivers when scrolling on desktop platforms (as reported in
#166822).

The fix uses a single `DecoratedSliver` wrapping a `SliverMainAxisGroup`
instead of two separate `DecoratedSliver` widgets. This eliminates the
gap while still demonstrating the widget effectively.

Fixes https://github.com/flutter/flutter/issues/166822

[material/menu_anchor.dart] Add animations to MenuAnchor. (#176494)
* Adds MD3 animations to MenuAnchor. 
* Adds a "hoverOpenDelay" parameter on `SubmenuButton`
* Moves the layout algorithm from SingleChildLayoutDelegate to a custom
render object. <s>This was done because I needed to access the dry
layout of the menu panel for the best effect. I'll demonstrate
below.</s> Turns out using dry layout significantly limits what children
you can use with a widget. As a result, I'm calculating the final height
using the inverse height factor.

Fixes https://github.com/flutter/flutter/issues/135025

I don't have access to the internal Google documentation, so I did my
best to deduce the spec from
https://github.com/material-components/material-web/blob/main/menu/internal/menu.ts.

This change is currently opt-in via an `animated` parameter on
`MenuAnchor` and `SubmenuButton`. As a result, this is not a breaking
change. Because the PR is already quite large, I chose to not add
animation customization to this PR. I also didn't change any theming
files or `DropdownMenu`.

The only other API addition is a `hoverOpenDelay` parameter on
`SubmenuButton`. This parameter delays the start of a submenu opening by
the specified duration. It is independent of the `animated` parameter.

When `animated == false`, the menu runs its forward and reverse
animations with a duration of 0. I originally disposed of all animation
assets when `animated` was false, but found that the code/testing
complexity to be unwieldy.

<s>Blocked by https://github.com/flutter/flutter/pull/176503</s>

## Examples

* Basic example adapted from material-web

* Example showing scrollbar

Thanks to @QuncCccccc and @dkwingsmt for [their work on this
issue.](https://github.com/flutter/flutter/pull/143416) Sorry for
throwing a wrench into the original PR by introducing `RawMenuAnchor`...

CupertinoSheetRoute with scrolling and dragging (#177337)
Fixes #161687

Enables scrollable content within the sheet to work together with the
dragging animation.

Flutter:


https://github.com/user-attachments/assets/3a9994e3-078a-410e-8288-95592713ab39



Native:


https://github.com/user-attachments/assets/c0bd46fb-26f5-41a6-bf42-6c78c23ddf34

Fling when scrolling to the top vs fling when the scrollable content is
already at the top


https://github.com/user-attachments/assets/e934facc-36d2-4e81-9ccd-a3e9dd7b6201



When scrolling is enabled, then the sheet will no longer have a drag
gesture recognizer over the sheet content, and will instead rely on the
scrollable content to trigger the drag. A non-scrolling area can be
wrapped with `CupertinoSheetDragArea` to put a drag gesture recognizer
only on that area, convenient for navbars. See
[cupertino_sheet.3.dart](https://github.com/flutter/flutter/pull/177337/files#diff-3df71aa5e6ddb6184007a85e847a9a4883515697b7014764e1978d240d72e0e1)

clean up usages of resetXyz for TestFlutterView (#180840)
While reviewing https://github.com/flutter/flutter/pull/180728 we
noticed that usage of `TestFlutterView.resetXyz()` was quite liberal and
some places benefit from using `TestFlutterView.reset()`, to avoid
repetition.

This PR cleans that up.

Add TabBar API example for scroll notification integration (#180728)
- A part of: https://github.com/flutter/flutter/issues/123965
- Description: This PR adds an example that came from
https://github.com/flutter/flutter/issues/123965#issuecomment-3722456594
as a workaround. I bring it into an API example so that users can find
it easier.
The example showcases how to apply custom behavior based on the scroll
in TabBar. It utilizes scroll notifications (ScrollMetricsNotification
and ScrollNotification) within NotificationListener callback to monitor
the scroll offset, allowing for interface customization based on the
obtained offset.

Fix draggable scrollable sheet example drag speed is off (#179179)
- Fix https://github.com/flutter/flutter/issues/179102
- In this PR:
- Fix the sheet position so that it will follow the pointer, even when
dragging mouse beyond the window then returns inside.
    - Some improvement for coding convention:
- declare minChildSize and maxChildSize const(s) then use them in the
hardcoded positions
- move `_isOnDesktopAndWeb` out of Grabber, so it's easier to see
Grabber widget purpose when reading the code

[Material] Change default mouse cursor of buttons to basic arrow instead of click (except on web) (#171796)
Changes default mouse cursor of Material buttons to basic arrow instead
of click as per updated Android guidance.

For each Material button, I did the following:

1. Changed the default mouse cursor to the basic arrow.
2. Added a way to configure the mouse cursor of the button if a method
did not exist before.
3. Added a test to ensure that the default mouse cursor is now the basic
arrow (or modified an existing one if applicable).
4. Added a test to ensure that the customization of button mouse cursors
still works (if currently untested).

The list of Material buttons I modified (supposed to be all of them):

- RawMaterialButton
- DropdownButton
- FloatingActionButton
- ToggleButtons
- ElevatedButton
- IconButton
- FilledButton
- OutlinedButton
- PopupMenuItem
- InkWell
- TextButton
- MaterialButton
- DropdownMenuItem
- DropdownButtonFormField
- BackButton
- CloseButton
- DrawerButton
- EndDrawerButton
- PopupMenuButton
- MenuItemButton
- CheckboxMenuButton
- RadioMenuButton
- MenuBar
- SubmenuButton
- SegmentedButton
- FilterChip
- ChoiceChip
- ActionChip
- InputChip

Fixes https://github.com/flutter/flutter/issues/170296.

Update image.error_builder.0.dart to replace the emoji with some text (#176886)
fixes #174805
after some investigation i found that `dart doc ` only understands
`utf-8 encoding` so providing an `emoji` for example breaks it(no crash
but not the intended behavior).

Migrate some files to use WidgetState (#174486)
Follow up of https://github.com/flutter/flutter/pull/174421

Migrate some files from `MaterialState` to `WidgetState`. This PR only
focus on `WidgetState` for a subset of files.
- This minimizes conflicts and reduces the size of the PR for easier
reviews and follow up
- I'll work on the other elements of
`packages/flutter/lib/src/material/material_state.dart` into other PRs

Feat: Add momentary varient of CupertinoSlidingSegmentedControl (#164262)
This PR introduces a new boolean flag, `isMomentary`, to the
`CupertinoSlidingSegmentedControl` widget.

When `isMomentary` is set to `true`, the segmented control behaves like
a momentary switch. Selecting a segment triggers its associated action
(e.g., via `onValueChanged`), but the segment doesn't stay visually
selected after the interaction ends. The control visually returns to its
previous state or a default state (often no segment selected).

When `isMomentary` is `false` (the default behavior), the control
maintains the selection state visually, highlighting the last chosen
segment.

**Motivation**

Currently, `CupertinoSlidingSegmentedControl` always maintains a
selected state. There are use cases where developers might want to use
the segmented control purely for triggering actions without persisting a
visual selection state, similar to how a `UISegmentedControl` can be
configured on iOS with `isMomentary = true`. This provides more
flexibility and aligns the Flutter widget closer to its native
counterpart's capabilities.

For example, this could be useful for triggering sorting actions, view
changes, or other immediate operations where maintaining a persistent
"selected" state isn't desired or meaningful.

Route transition duration (#171109)
We need a robust way to get the duration of a route transition in tests,
so that tests can remain independent of the type of route transition and
its duration.

With this PR, this will be the canonical way to pump until a page
transition has finished:

```dart
testWidgets('example', (WidgetTester tester) async {
  final TransitionDurationObserver observer = TransitionDurationObserver();

  await tester.pumpWidget(
    MaterialApp(
      navigatorObservers: <NavigatorObserver>[observer],
      onGenerateRoute: (RouteSettings settings) { ... },
    ),
  );

  expect(find.text('Page 1'), findsOneWidget);
  expect(find.text('Page 2'), findsNothing);

  // Pump through the whole transition.
  await tester.tap(find.text('Next'));
  await observer.pumpPastTransition(tester);

  expect(find.text('Page 1'), findsNothing);
  expect(find.text('Page 2'), findsOneWidget);

  // Or, pump through part of a transition with the duration.
  await tester.tap(find.text('Back'));
  await tester.pump(observer.transitionDuration ~/ 2);

  expect(find.text('Page 1'), findsOneWidget);
  expect(find.text('Page 2'), findsOneWidget);
});
```

This was spun out of https://github.com/flutter/flutter/pull/165832,
where updating the default route transition and its duration broke tests
in the framework, in customer tests, and in Google tests.
