* Restore clipBehavior to make it non-breaking
* Small fixes
* Fix rebase
* Uses a special cursor value MouseCursor.defer to mark deferring. MouseTrackerAnnotation.cursor is now non-null. The mouseCursor argument of widgets or render objects can be null, which indicates using the default value.
* Moves SystemMouseCursors.uncontrolled to MouseCursor.uncontrolled.
* Changes how MouseCursor.debugDescription is defined. Previously MouseCursor.toString returns $runtimeType($debugDescription), while now it returns $debugDescription. Implementations of classes are updated, except for the ones of MouseCursor.defer and MouseCursor.uncontrolled are simply "defer" and "uncontrolled".
The arrow key and delete handling in RenderEditable was using single
index values, which made it possible to move the cursor into the middle
of a surrogate pair (allowing things like adding text at that insertion
point), or to delete half of a surrogate pair. Since unpaired surrogate
pairs aren't valid UTF-16, doing so would cause assertions in the text
field.
This makes the arrow key and delete key handling surrogate-aware
(although not grapheme-cluster-aware, which is a larger fix that is out
of scope here).
Part of #55014
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 PR adds the linux and windows target platform enum values, along with automatically setting the defaultTargetPlatform to the appropriate value on those platforms.
Fixes#31366
This PR is a follow up of https://github.com/flutter/flutter/pull/42640
Some changes of that PR includes redundant changes using FlutterError.fromParts constructor even though it's not necessary.
Some minor changes are:
- Remove one unnecessary todo
- Fix indent consistencies
