The TapGestureRecognizer in the test named 'TapGestureRecognizer _sentTapDown toString' was not disposed, which was breaking a couple of other tests.
This worked fine when not shuffling the tests as the test was executed last.

Fixes test/animation/animation_controller_test.dart in #85160

Problem:
The test 'animateTo can deal with duration == Duration.Zero' was failing with the following error:

Expected: <0>
Actual: <5>
Expected no animation.
package:test_api expect
package:flutter_test/src/widget_tester.dart 484:3 expect
test/animation/animation_controller_test.dart 511:5 main.

Following line finds 5 transientCallbacks scheduled, while expecting zero, if shuffled with seed 123:

expect(SchedulerBinding.instance!.transientCallbackCount, equals(0), reason: 'Expected no animation.');

This is caused by some other test leaving transientCallbacks scheduled.

Fix:
By disposing the AnimationController after each test, the transientCallbacks get cleaned up.
I chose to dispose all controllers in every test, to make sure there is no risk of leaks.

This reverts commit 91e0759b.

Moving the focus with the tab key on the external keyboard will move the focus to the widget that is hidden by AnimatedCrossFade.

Corrects the exact definition in code and docs of ScaleUpDetails delta.

Support for more desktop keyboard keys/shortcuts.

Switch document generation to use the snippets package instead of the snippets code in the Flutter repo. In the process, some bugs in sample code analysis have been fixed, and I've fixed some more errors in the samples.

This will allow the snippets package to be developed separately from the Flutter repo, and reduce the code in the Flutter repo.

The snippets code is deleted in this PR.

I also converted some comments in the snippet templates to be regular comments instead of doc comments, because having a doc comment block before the imports causes the Dart import sorter to lose the comment. They should have been regular comments in the first place.

The snippets package resides in the assets-for-api-docs repo.

The sample analysis has also been converted to be run in parallel, and I've bumped the Dartdoc version to 1.0.2.
