onSemanticsEnabledChanged property
- @Deprecated('Use WidgetTester.platformDispatcher.onSemanticsEnabledChanged instead. ' 'Deprecated to prepare for the upcoming multi-window support. ' 'This feature was deprecated after v3.9.0-0.1.pre.')
- @override
override
A callback that is invoked when the value of semanticsEnabled 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 framework invokes this callback in the same zone in which the callback was set.
