Just some very minor doc changes: an adjustment of my comments in #51495, and a typo fix.

Adds an overflow menu to the text selection menu on Android when the items overflow.

This converts Diagnosticable to be a mixin instead of an abstract class, so that it can be used to add diagnostics to classes which already have a base class.

It leaves in place the DiagnosticableMixin mixin, since there are some plugins that are still using it, and removing it would mean that those plugins wouldn't work with master branch Flutter anymore. DiagnosticableMixin will be removed once this mixin version of Diagnosticable makes its way to the stable branch.

This adds a sample for InheritedNotifier, and converts a couple of other samples to be DartPad samples. I also added a new sample template stateful_widget_material_ticker, which adds a TickerProviderStateMixin to the state object so that animation controllers can be created there easily.

Revert "Add missing features to `DefaultTextStyleTransition` and `AnimatedDefaultTextStyle` (#51517)" (#52352)

This reverts commit 91b0bcf1.

Add width constraints for FlexibleSpaceBar.title in its expanded state, so that overflow of long titles can be handled (#51335)

* Fix for negative padding from a curve in AnimatedPadding.

* Added a EdgeInsets.clamp function that would return an EdgeInsets instance instead of a _MixedEdgeInsets used by the base class. This was causing some tests to fail that didn't have a text direction.

Keep render tree and element tree in sync when re-used elements move in a MultiChildRenderObjectElement's child list (#51674)
