updateSemantics method Null safety
- SemanticsUpdate update
override
Change the retained semantics data about this platform dispatcher.
If semanticsEnabled is true, the user has requested that this function be called whenever the semantic content of this platform dispatcher changes.
In either case, this function disposes the given update, which means the semantics update cannot be used further.
Implementation
@override
void updateSemantics(ui.SemanticsUpdate update) {
_platformDispatcher.updateSemantics(update);
}
