Adds tests for `relative_positioned_transition`, `positioned_transition`, `sliver_fade_transition`, `align_transition`, `animated_builder`, `rotation_transition`, `animated_widget`, `slide_transition`, `listenable_builder`, `scale_transition`, `default_text_style_transition`, `decorated_box_transition`, `size_transition` api examples. Makes double type in the `align_transition` example explicit.
A test for `fade_transition` is already in currently open #148178.
Part of #130459.
Adds tests to the last two Snack Bar examples as part of #130459. Makes the [last example](https://api.flutter.dev/flutter/material/SnackBar-class.html#material.SnackBar.3) more usable through the use of standard widgets and visual hierarchy. Constraints on options that are not required by the SnackBar contract have been removed (Overflow threshold works on fixed SnackBars).
This is part 16 of a broken down version of the #140101 refactor.
This only makes one dependency explicit. Further PRs will do the same for other dependencies, until these APIs have no hidden dependencies.
This PR makes no effort to keep the order of parameters reasonable. There is an existing TODO to do a refactor sweep later that does nothing but reorder arguments/parameters/fields to be consistent.
Both iOS and Android run into issues when the FocusManager starts responding to app lifecycle changes.
Fortunately, this feature is primarily meant for desktop platforms, so the problem can be resolved with a platform check.

It adds test for
- `examples/api/lib/material/scaffold/scaffold.0.dart`
- `examples/api/lib/material/scaffold/scaffold.2.dart`
It also modifies the `scaffold.1_test.dart` because the only difference with scaffold 0 is the background color, so I figured the test should include it

### Description
- Updates `examples/api/lib/widgets/restoration_properties/restorable_value.0.dart` to meet the latest API examples structure
- Adds tests for `examples/api/lib/widgets/restoration_properties/restorable_value.0.dart`
This PR modifies the `flutter create --empty` command to not delete the `test/` folder when run on an existing app project.
Before:
```bash
flutter create my_app --empty
mkdir my_app/test
if test -d my_app/test; then echo "test exists"; else echo "test does not exist"; fi # test exists
flutter create my_app --empty
if test -d my_app/test; then echo "test exists"; else echo "test does not exist"; fi # test does not exist
```
After:
```bash
flutter create my_app --empty
mkdir my_app/test
if test -d my_app/test; then echo "test exists"; else echo "test does not exist"; fi # test exists
flutter create my_app --empty
if test -d my_app/test; then echo "test exists"; else echo "test does not exist"; fi # test exists
```

This PR adds support invoking `link.dart` hooks.
Link hooks can add new assets. Link hooks can transform assets sent to link hook from build hooks.
This PR does not yet add support for getting tree-shake information in the link hooks. This is pending on defining the `resources.json` format (https://github.com/dart-lang/sdk/issues/55494).
Issue:
* https://github.com/flutter/flutter/issues/146263
## Implementation considerations
The build hooks could be run before Dart compilation and the link hooks after Dart compilation. (This is how it's done in Dart standalone.) However, due to the way the `Target`s are set up, this would require two targets and serializing and deserializing the `BuildResult` in between these. This would lead to more code but no benefits. Currently there is nothing that mandates running build hooks before Dart compilation.
## Testing
* The unit tests verify that the native_assets_builder `link` and `linkDryRun` would be invoked with help of the existing fake.
* The native assets integration test now also invokes an FFI call of a package that adds the asset during the link hook instead of the build hook.
* In order to keep coverage of the `flutter create --template=package_ffi`, `flutter create` is still run and the extra dependency is added and an extra ffi call is added. (Open to alternative suggestions.)
This PR is to
* Update the Material Design tokens to 4.0.0
Since the last token update(#145356), only `Slider` tokens have been updated. The M3 `Slider` has significant visual changes, compared to the original M3 Slider, so a separate PR would be needed. I commented out `SliderTemplate` and added a TODO when we are ready to add new widgets again.

### Description
- Updates `examples/api/lib/widgets/actions/actions.0.dart` to meet the latest API examples structure
- Adds tests for `examples/api/lib/widgets/actions/actions.0.dart`
This PR adds a new flag `default-flavor` in the `flutter` section of `pubspec.yaml`. It allows developers of multi-flavor android apps to specify a default flavor to be used for `flutter run`, `flutter build` etc.
Using `flutter run` on flavored apps already works without specifying `--flavor` already works on iOS (it defaults to the `runner` schema), so I (and others in #22856) figured this would be nice to have.

Tests in Material toggleables (`Radio`, `Switch`, `Checkbox`) which require hovering using a mouse pointer do not include `addTearDown(gesture.removePointer)` to remove the mouse pointer once the test concludes.
Also, hovering tests in Material `Checkbox` currently have no functionality (i.e what is painted before hovering = what is painted while hovering). For example:
357bd65749/packages/flutter/test/material/checkbox_test.dart (L880-L896)
This PR adds `addTearDown(gesture.removePointer)` to `Radio`, `Switch`, and `Checkbox` tests, and functionality for `Checkbox` hover tests.
Fixes#148809.

Repro:
`flutter test test/cupertino/tab_scaffold_test.dart --dart-define LEAK_TRACKING=true --plain-name "Adding new tabs does not crash the app"`
What is going on:
1. ImageCache.putIfAbsent, in case the image already existed in the cache, invokes ImageCache._trackLiveImage, that creates _LiveImage and passes the image's completer as parameter `completer`
3. _LiveImage constructor invokes super constructor (of _CachedImageBase) that initializes the member `handle`
4. `handle` is disposed [using scheduler](c698e694c8/packages/flutter/lib/src/painting/image_cache.dart (L633)), and disposal does not happen in time of test completion.
Adding delay to the test increases number of not disposed objects from 30 to 120.
Should we force schedule at the end of the widget tests somehow to make scheduler switched to right state?

These also get printed out to the CLI, so they are somewhat annoying.
Fixes all of the warnings, except for `'Version' is deprecated. Deprecated in Java`, which gets suppressed (we are intentionally using the deprecated `Version`, to help support older versions of AGP that use that deprecated class).
