Member Function Documentation

updateCustomAccessibilityActions()

void io.flutter.embedding.engine.FlutterJNI.AccessibilityDelegate.updateCustomAccessibilityActions	(	@NonNull ByteBuffer	buffer,
		@NonNull String[]	strings
	)

Sends new custom accessibility actions from Flutter to Android.

Implementers are expected to maintain an Android-side cache of custom accessibility actions. This method provides new actions to add to that cache.

updateSemantics()

void io.flutter.embedding.engine.FlutterJNI.AccessibilityDelegate.updateSemantics	(	@NonNull ByteBuffer	buffer,
		@NonNull String[]	strings,
		@NonNull ByteBuffer[]	stringAttributeArgs
	)

Sends new SemanticsNode information from Flutter to Android.

Implementers are expected to maintain an Android-side cache of Flutter's semantics tree. This method provides updates from Flutter for the Android-side semantics tree cache.
