of static method
The ObservableLocator
of the closest ObservableLocatorScope that
surrounds the given context.
If listen
is true, any changes to the surrounding observable locator
scope will trigger a new State.build to widgets, and
State.didChangeDependencies for StatefulWidget.
listen: false
is necessary to be able to call this method inside of
State.initState.
Implementation
static ObservableLocator of(BuildContext context, {bool listen = true}) {
assert(_debugCheckHasLocator(context));
final element = context.getElementForInheritedWidgetOfExactType<
_InheritedObservableLocatorScope>()!;
if (listen) {
context.dependOnInheritedElement(element);
}
return (element.widget as _InheritedObservableLocatorScope).locator;
}
