This updates `AsyncSnapshot.data` to act as `AsyncSnapshot.requireData`
used to -- and it removes `AsyncSnapshot.requireData`. Correspondingly,
this adds a `StreamBuilder.withoutInitialData()` constructor, makes the
`initialData` argument to the default `StreamBuilder()` constructor required,
and deprecates the `initialData` argument to the `FutureBuilder()` constructor.

This PR makes ModalBarrier dismiss modal with any button press instead of primary button up, by making it use a private recognizer _AnyTapGestureRecognizer that claims victor and calls onAnyTapDown immediately after it receives any PointerDownEvent.
FocusTraversalPolicy keep the previously visited node to avoid hysteresis. But even if the visited focus has been disposed, FocusTraversalPolicy will still use it to requestFocus, which will cause FocusManger to get an abandoned node to get the focus.
Added support for a semi-transparent white overlay color for `Material` widgets to indicate their elevation in a dart theme. A new `ThemeData.applyElevationOverlayColor` flag was added to control this behavior, which is off by default for backwards compatibility reasons.
This adds an example of how to move to the "next" field when using TextInputAction.next. This is all that is needed to have "next field" functionality in a field. I thought about making it the default when handling the "next" or "previous" actions, but it's better that the developer has control over whether or not they actually move to the next field, and within which scope.
This changes the example for FocusNode to be more correct, listening to the focus node for changes, instead of assuming that it is the only one doing the changing.
* Remove extra classes.
Now that https://github.com/dart-lang/sdk/issues/31543 is fixed, we
can remove extra classes.
* Add snapConfiguration to parameters for _RenderSliverFloatingPersistentHeaderForWidgets and _RenderSliverFloatingPinnedPersistentHeaderForWidgets constructors.
* Add Colors.white38
* Update ThemeData.disabledColor and ButtonThemeData.disabledColor to Colors.white38
* Update pre-existing tests to expect Colors.white38 instead of Colors.white30
* Update API documentation to reflect these changes
When I added reverseDuration to animation controllers in #32730, I also added it to the implicit animations that Flutter has. However, as @efortuna pointed out to me, it doesn't actually do anything there, since all of the intrinsic animations run forwards, not in the reverse direction, and there's no way to reverse them.
So, this PR removes the reverseDuration argument from the implicit animations to avoid confusion.
Fixes#35769
* add sample code for AnimatedContainer
* use stateful_widget_scaffold snippet template
* add sample explanation
* add setState() to example assumptions for analyzer
* update description
* use snippet instead of sample
* change sample to match assets-for-api-docs
* remove constant
* update AnimatedContainer sample description
add indication the example is depicted by the video and animates when
tapped
* fix example formatting
* make sample conform to 80 col limit
* add "implemented below" to illustration description
* formatting for readability
This PR adds a new parameter to RawGestureDetector, `semantics`, which configures how detectors handle semantics gestures. It has a default delegate that keep the current behavior.
