* add a FAB NotchMaker to ScaffoldGeometry
* add a notchMaker to FloatingActionButton
* Initial implementation of BottomAppBar
Mainly includes the notch making logic.
Not yet tested as currently there is no way to make the FAB and the BAB
overlap, once #14368 to lands we could add unit tests to the
BottomAppBar as well.
* use a closeable for clearing the FAB notchmaker
* Use engine-built dart sdk
* Download dart-sdk from engine
* Move up deps to fix dart sdk constraint problem
* Update update_dart_sdk.ps1 for Windows
* Fix tests so they pass analysis
* More types for tests
* Roll engine
* Update dart sdk stamp location in flutter.bat
* Add newline
Adds a ScaffoldGeometry class and ValueNotifier for it.
A scaffold's ScaffoldGeometry notifier is held in the _ScaffoldState, and is passed to _ScaffoldScope.
New ScaffoldGemometry objects are built and published to the notifier.
This adds geometric sort ordering back in for semantics nodes that don't have a sort order defined.
With this change, widgets that either have no sort order, or have an equivalent sort order, will be compared geometrically. The comparison is between the two starting corners, so it is TextDirection-aware: parent nodes that are set to have LTR text will compare upper left corners of their children, and upper right when set to RTL.
Also fixed a bug in the Transform widget that didn't mark modified nodes as needing a semantics update.
It seems that setTraversalBefore doesn't work as well as setTraversalAfter for some reason, although I'm using them the same way. Some apps would lock up TalkBack when traversing if setTraversalBefore was set, but not with the equivalent setTraversalAfter.
It's not entirely clear why this is, but I'm going with this to at least get it fixed for apps we know about.
Fixes#14600
* Roll engine to pre-dart roll
* Roll engine to pick up updated dart
* Apply Map changes
* Move to dev.22
* Fix some analysis issues
* Silent analyzer
* More consts
* More const massaging
* Yet more const massaging
* Yet more const massaging
* Use nonconst()
This allows const GlobalObjectKey(0) to be concisely formatted as
[GlobalObjectKey int#0000] in both Dart 2 and Dart 1 modes.
Without this change it would be formatted as
[GlobalObjectKey<State<StatefulWidget>> int#0000] because in Dart 2
types are instantiated to bounds.
In addition to retaining general readability this also fixes few
tests that rely on this short string representation (see
test/widgets/global_keys_duplicated_test.dart).
Channels don't preserve Map and List type arguments: Map<String, Object>
arrives as Map<dynamic, dynamic> to the receiver.
In Dart 2 type system dynamic no longer serves as bottom type so
Map<dynamic, dynamic> can't be assign to a variable of type
Map<String, dynamic>.
Issue #14556
Use mockito in the Dart 2 compliant way:
* use typed(...) in appropriate places to wrap matchers like any;
* don't pass matcher directly into the calls - use `argThat(matcher)`.
Also rename paintColorMatcher to hasColor to match how other similar
functions are named and how the code reads.
* Use explicit types for onClick handler in diagnostics_test.
This test formats it to string and expects exact match.
Before this change onClick had type () => dynamic in Dart 1 and () => Null in
Dart 2.
* Fix strong mode issues in packages/flutter/test/material/dropdown_test.dart
Pass explicit type argument to renderObjectList(...) in expressions like
List<RenderBox> l = tester.renderObjectList(...).toList();
Dart 2 mode inference is not strong enough to infer RenderBox as a type argument
fto renderObjectList and passes RenderObject instead, which later leads to
runtime check failures (because List<RenderObject> is not List<RenderBox>).
* Fix strong mode issues in packages/flutter/test/material/theme_test.dart.
Pass type argument explicity to widgetList. Dart 2 type inference can't infer
it by itself.
* Fix strong mode issue packages/flutter/test/widgets/unique_widget_test.dart
Pass correct type argument to GlobalKey.
* Fix type annotation in packages/flutter/test/material/app_test.dart.
pushNamed returns Future<Object> not Future<String>.
