semanticsEnabled property Null safety
Whether the user has requested that updateSemantics be called when the semantic contents of window changes.
Accessing this value returns the value contained in the
PlatformDispatcher singleton, so instead of getting it from here, you
should consider getting it from WidgetsBinding.instance.platformDispatcher instead
(or, when WidgetsBinding isn't available, from
PlatformDispatcher.instance). The reason this value forwards to the
PlatformDispatcher is to provide convenience for applications that only
use a single main window.
The onSemanticsEnabledChanged callback is called whenever this value changes.
Implementation
bool get semanticsEnabled => platformDispatcher.semanticsEnabled;
