Also:

* Fix IconData's operator== and hashCode, which had not been updated when we added fields.
* Add the byTooltip finder to the list of suggested finders.
* Make the suggested Key finder prettier.
* make time picker accessible
* use new CustomPaint a11y API
* flutter_localizations tests; use bigger distance delta
* fix am/pm control; selected values
* fix translations; remove @mustCallSuper in describeSemanticsConfiguration
* exclude AM/PM announcement from iOS as on iOS the label is read back automatically
* Let translucent Cupertino bars have its scaffold children automatically pad their heights (#13194)
* Let lists automatically add sliver padding from media query. Translucent nav and tab bars leave behind media query paddings in scaffolds.
* tests
* const lint
* Rename base abstract class to generalized ObstructingPreferredSizeWidget
* review
* More docs and comments from #13317
This allows the scheduler library to depend on the services library
and the painting library to depend on the scheduler library without
the services library having to depend on the scheduler library.
While I was at it I also cleaned up some of the binding logic: the
licenses logic can now be overridden (and the test library does so),
and the image cache can now be overridden as well.
Summary:
- Add `key` field to `SemanticsNode`, while moving key into `foundation` library so it can be used by the render layer.
- Introduce `SemanticsProperties` and move many of the `Semantics` fields into it.
- Introduce `CustomPaintSemantics` - a `SemanticsNode` prototype created by `CustomPainter`.
- Introduce `semanticsBuilder` and `shouldRebuildSemantics` in `CustomerPainter`
**Breaking change**
The default `Semantics` constructor becomes non-const (due to https://github.com/dart-lang/sdk/issues/20962). However, a new `const Semantics.fromProperties` is added that still allowed creating constant `Semantics` widgets ([mailing list announcement](https://groups.google.com/forum/#!topic/flutter-dev/KQXBl2_1sws)).

Separate focus management by build owner
Currently the focus manager is held by the singleton WidgetBinding.
This change places a focus manager in each build owner object,
which allows clients to run offscreen pipelines without disturbing
focus management for the main UI.
1. Ensure that this value is defaulted to the value associated with the
context rather than re-defaulted to false.
2. Add this value to operator==, hashCode, toString methods.
* Let lists automatically add sliver padding from media query. Translucent nav and tab bars leave behind media query paddings in scaffolds.
* tests
* const lint
* Rename base abstract class to generalized ObstructingPreferredSizeWidget
* Add MediaQuery support for view insets
Also updates EdgeInsets documentation to reflect WindowPadding's use for
both padding and view insets.
See engine commits:
flutter/engine#4403flutter/engine#4406
* ensures that only semantics boundaries will be added to owner._nodesNeedingSemantics as expected by compiler.
* no longer throws assert if markNeedsSemanticsUpdate is called on non-semantic-boundary render object with a non-semantic-boundary parent.
* Fixes#13109.
* removes onlyLocalUpdates from markNeedsSemanticsUpdate as its no longer needed.
Fix the dismissible demo in the gallery (make it actuall update when you pick something from its menu; give it a better affordance for resetting once you've dismissed everything).
Improve some docs.
Fix various flinging bugs with dismissible. Add tests for those cases.
Add a feature to flutter_test to support a drag-then-fling gesture (used by the flinging tests).
This makes sure that we don't decode frames when we don't need to run
the animation.
For example, prior to this CL: an animated image in a page that is not
currently at the top of the page stack (it is covered by another page),
will keep the the image stream listener, and thus frames will still be
decoded.
I got tired of drive-by spelling fixes, so I figured I'd just take care of them all at once.
This only corrects errors in the dartdocs, not regular comments, and I skipped any sample code in the dartdocs. It doesn't touch any identifiers in the dartdocs either. No code changes, just comments.
Previously, ExpansionPanel would do weird things if interacted with
when it was already animating. This is fixed and there's now a test.
Also:
* Minor fixes to make the gallery work in RTL, not that there's
any way to see that without hard-coding the framework to RTL.
But at least I'll be less annoyed when doing that.
* Some trivial code and documentation cleanup.
* PageView ballistics overshoot the page on some devices
On some devices, such as Cupertino “Plus”-sized devices, scrolling left on the first page of a PageView will overshoot the first page and land on the second page.
The issue is that applyContentDimensions incorrectly detects a content size change due to a floating point comparison on certain screen sizes (18257.400000000005 vs 18257.4)
To fix this, perform a nearEqual comparison in applyContentDimensions.
* Apply style changes to nearEqual for code review feedback.
Since MethodCall equality checks are limited to test scenarios, this
patch replaces them with an equivalent test matcher. At present
MethodCalls are always used in scenarios where indentity-based
equality/hashing is appropriate.
This change avoids an assertion failure when MethodCall args are
Iterable (possible since args are of type dyanmic), and hashValue() from
dart:ui asserts that its input is not an Iterable.
The alternative of implementing support for deep equality in dart:ui was
rejected on the basis that if we're to encourage performant code,
expensive checks should be obviously-expensive to the author.
Various improvements (in particular a new painting fuzzer) to the text manual test.
Some additional documentation.
A fix to Stack to remove an LTR bias: make unpositioned children apply "alignment".
Some more debugging information on RichText and Text.
A fix to the flutter tool to not crash when an RPC call throws an exception.
* Add a pageSnapping parameter to PageView
Setting the pageSnapping property allows extending the PageView scroll
behavior, such as custom scroll animations or custom scroll bars.
* Apply pageSnapping CR feedback
- Remove _kNonSnappingPhysics, use null instead.
- Minor code style fixes.
- It turns out that the forth state is Arkansas, not California.
This adds an optional character counter and maxLength parameter to the TextField, as described in the Material Design Spec.
The counter text and style in the input decorator may be specified, but will default to the "right thing" if not specified, where the "right thing" is a counter that looks like "3 / 10" (if there are three characters entered into a field where maxLength is set to 10).
To limit the number of characters entered, I created a LengthLimitingTextFormatter that will limit the number of characters (Unicode runes) in the input, which can be used independently. The formatter is applied after the other formatters supplied (if any). Even if there is no decorator, the text field will limit the number of characters input if maxLength is set.
If maxLengthEnforced is set to false (it defaults to true), then the max length will not be enforced. In that case, if the text exceeds the length, then the counter will turn red, and it will make the divider turn red.
* Revert "Construct the accessibility channel's events by SemanticsEvent. (#12638)"
This reverts commit 4c1150dd01c0efb55278d35a9ce1467a65c45e40.
* Revert "Revert "Add a way to get the furthest Navigator" (#12608)"
This reverts commit 79f13c36258380408eb1a1738178b964be3bf7f3.
This refactoring allows us to have SemanticsEvent object for events that are not
associated with an accessibility node id.
And allow https://github.com/flutter/flutter/pull/12594 to be a bit
cleaner with a single place for accessibility channel documentation (the
SemanticsEvent classes documentation).
