Developers may get confused by setting PaintingBinding.shaderWarmUp in
the wrong place. The added assert and error message help avoid that.

Fixed a misuse of matchesGoldenFile() in the physical_model_test so that it correctly reports a failed test on Linux (and skips the other platforms).

This tries to make it more obvious when someone checks the "tests" box without actually having added tests.

* write newline before adding slow restart message to spinner
* update existing test

* Embedding new diarams for API docs: Container, ListView, Align.

* Moving the diagrams to be enclosed within the snippet windows.

* Fixed wording for the alt image text.

Include the platformViewId of PlatformViews in the semantics tree. The accessibility bridge in the engine can use this id to steal the semantics nodes from the actual platform view and stick them into Flutter's semantics tree.

It is the iOS PlatformView counter part of https://github.com/flutter/flutter/pull/28953. It reverts the change in https://github.com/flutter/flutter/pull/28953/commits/5b5d6e89ec50f8f51766fb778d0e244f183a5000 and https://github.com/flutter/flutter/pull/28953/commits/03fd797eb8955561c2654b51035175202a25da9d.

https://github.com/flutter/flutter/issues/29302

Unblock the engine roll that includes the Dart roll that removes `-c`.

Documented CupertinoSwitch.value that it can't be null and added an assertion value != null in the constructor.

Related issue: #12948

Documentation that explains a common use case seen in Github issues where users were surprised by TextFormField growth to accommodate validation messages.

Remove the additional top padding from CupertinoPageScaffold's MediaQuery when the navigation bar is opaque (as the padding was already consumed by the navigation bar).

Related Issue: #29136

Avoids an implicit downcast + crash in MouseTracker, since the last
pointer event can be a Move or Down event, in addition to Hover.

The UserAccountsDrawerHeader had a bug with the arrow rotating whenever setState was called on its parent. This change makes sure that we check that the state actually changed before allowing the animation to trigger.

Fixes #25801

* Adding linking between higher and lower level classes in the API Docs. ref:#22859

* Fixed links between classes.

This PR limits the framework generated semantic node IDs to be smaller than 2^16, this allows to safely generate semantic node in the engine with IDs >= 2^16 avoiding ID collision (which is done in flutter/engine#8250).
