I am inclined to approve. @LongCatIsLooong, you had mentioned this being similar to another feature in flutter/engine#15343. @miquelbeltran provided some feedback there on that, do you have any objections to this change moving forward?

We should land the change in the engine before landing this.

We should separately land a change to the framework to make FakeAccessibilityFeatures override noSuchMethod so that the engine will bea ble to roll the change into the framework. See the way we do it on TestWindow for an example.

@dnfield is right. I forgot that the engine will complain when you add highContrast and it isn't overridden.

Here is the example of NoSuchMethod @dnfield mentioned:

flutter/packages/flutter_test/lib/src/window.dart

Line 427 in 1be332e

/// This gives us some grace time when the dart:ui side adds something to

Adding that will actually open the door to making changes like this easier in the future! :)

Sorry for the delay, I have added now the noSuchMethod override.

Could you pull changes from upstream again? That should fix the test failure.

Once this lands, we should be able to move on to the follow-up engine change you have staged in flutter/engine#15343 :)
