The stream subscriptions in the device's VmService are used by other parts of FlutterVmService and other components throughout flutter_tools. Components that listen to streams should not call VmService.streamCancel because that will interfere with other users who still want the events.

The Flutter tool has a bug where removing the last Flutter plugin does not correctly update the CocoaPods integration.
This adds a test to ensure that the generated Swift package is properly updated when the last Flutter plugin is removed.

Addresses an issue where `DefaultTextStyle.merge` is missing the `textHeightBehavior` argument. The argument is present in the `DefaultTextStyle` constructor.
Resolves#120176
## Description
In debugging an issue with mount, I hit one of these asserts, and I thought it would be a much better assert with some context.
## Tests
- No test changes because the change is only to the output string of an assert.

Disabling filtering in `DropdownMenu` at start and after a selection has been made, and re-enable it (if `widget.enableFilter` is true) after text input.
This way it doesn't hide all other options when there is an existing selection.
Note: currently this may crush due to issue https://github.com/flutter/flutter/issues/151878 . Which is not directly related to this PR
When DevTools is active HotRunner.attach makes a deferred RPC to a DevTools service. That RPC appears to cause issues if it executes at the wrong time during the hot restart.
Passing the --no-devtools flag works around this by disabling the RPC.

This PR fixes#92525 and introduces the following changes according to [latest iOS HIG](https://developer.apple.com/design/human-interface-guidelines/buttons#iOS-iPadOS):
- `CupertinoButton` now has a `size` property (type `enum CupertinoButtonSize`, values sm/md/lg, default `lg`) that allows the devs to apply new iOS 15+ button styles
- Previously `CupertinoButton` had a larger padding when no background color was specified. With the new HIG, that is no longer the case
- `CupertinoButton` now has a `.tinted` constructor that renders a translucent background (transparency % is brightness-dependent) and uses a different foreground color compared to `.filled`
- `CupertinoButton` now uses the `actionTextStyle` TextStyle from the given theme
- `CupertinoButton`'s child IconTheme's size will always be x1.2 the given TextStyle's size
- `CupertinoTextThemeData` now has a `actionSmallTextStyle` property to use with small buttons (including a default `_kDefaultActionSmallTextStyle` TextStyle)
Preview & example:
> **NOTE**: there is a discrepancy in dark mode button foreground color between the default CupertinoTheme and the HIG. A separate issue will be opened for this.

## Description
This PR makes the existing `InputDecoration.prefixIconConstraints` and `InputDecoration.suffixIconConstraints` configurable from an `InputDecorationTheme`.
## Related Issue
Related to https://github.com/flutter/flutter/issues/138691 (this is needed before providing a fix or a workaround for it).
## Tests
Update and split one existing test into two different tests.
Update the existing test related to debugFillDescription by adding all the non tested properties.
The test should not assume that a stream of bytes delivers them in a
certain chunked order (e.g. all bytes of a line are delivered in one
chunk and the newline comes in another chunk).
Instead it should use a line splitter to obtain individual lines and can
match those against expectations.
This fragile test is broken after [0] which combines writing a string
together with the newline instead of seperately.

**Fixes #152846 in accordance with iOS HIG**
Previously the `_CupertinoThemeDefaults _kDefaultTheme` would set the `primaryContrastingColor` to `CupertinoColors.systemBackground`, which was white-ish in light mode, and black-ish in dark mode. That was in accordance with Apple Design Resources from 5 years ago.

> <img width="594" alt="image" src="https://github.com/user-attachments/assets/63e88abb-6933-446f-a7ba-55109d0f353c">
As of now, iOS HIG suggests that the `primaryContrastingColor` (in combination with the currently default `primaryColor: CupertinoColors.systemBlue`) be white (regardless of light/dark modes, contrast, elevation, etc.)
> After:
> <img width="594" alt="image" src="https://github.com/user-attachments/assets/2a48f22b-a886-46dd-aada-6d157cb4ac06">
Example code:
```dart
import 'package:flutter/cupertino.dart';
import 'package:flutter/widgets.dart';
void main() =>
runApp(
CupertinoApp(
theme: CupertinoThemeData(
brightness: Brightness.dark,
),
home: Center(child:
CupertinoButton.filled(
onPressed: () {},
child: Row(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Icon(CupertinoIcons.add),
Text('Add'),
],
),
)
)
)
);

Hide the `--web-renderer` option in the Flutter Tool. The defaults already cover all fully supported modes:
- `flutter build web` provides canvaskit + dart2js
- `flutter build web --wasm` provides skwasm + dart2wasm
We do not want to encourage production usage of any other permutations (e.g. `auto` or `html`), in particular those that simply do not work (e.g. `skwasm` + dart2js).

This PR guards all the writes to `Process::stdin` by wrapping them with `ProcessUtils.writelnToStdinUnsafe`. This way, if any writes fail, we should at least get a stacktrace in our crash reporting.
This change exposes:
* `SelectableRegionState.clearSelection()` to allow a user to programmatically clear the selection.
* `SelectionAreaState`/`SelectionAreaState.selectableRegion` to allow a user to access public API in `SelectableRegion` from `SelectionArea`.
Fixes#126980
This PR is aimed at (1) reducing the private API surface of _MenuAnchorState to make migration into RawMenuAnchor simpler, and (2) fixing focus-related bugs.
Directional focus handling was moved from MenuAnchor (_MenuDirectionalFocusAction, _MenuNextFocusAction, and _MenuPreviousFocusAction) into SubmenuButton (_SubmenuDirectionalFocusAction). MenuAnchor now behaves similarly to a flat FocusScope, which makes it easier to customize. A future PR will ideally expose or remove the remaining internals (_lastItemFocusNode, _firstItemFocusNode, _isRoot, etc). All previous framework tests are passing, and additional tests were added for fixes (MenuAnchor tab traversal, reopened menus not being focusable), and to test MenuAnchor focus behavior separately from MenuBar.
However, [one example test](https://github.com/flutter/flutter/pull/150950/files#diff-a33fa01b59d280784e7c8ed6b704bd005cde95b7d3b649dc82fd58530061a09d) had to be changed. I'm not sure why the previous example test was working to begin with, as submenu buttons are supposed to open on focus, but this behavior was not observed in the original test.
Fixes https://github.com/flutter/flutter/issues/144381, https://github.com/flutter/flutter/issues/150334.
One added feature is the ability to move between top-level horizontal submenus if a horizontal movement is made on a vertical menu item that has no children in the movement direction. This behavior was observed on Google Docs, MacOS, and various other menu systems I encountered.
