- BuildContext context
override
Returns the FocusScopeNode of the FocusScope that most tightly
encloses the given context.
If this node doesn't have a Focus widget ancestor, then the FocusManager.rootScope is returned.
The context argument must not be null.
Implementation
static FocusScopeNode of(BuildContext context) {
assert(context != null);
final _FocusMarker? marker = context.dependOnInheritedWidgetOfExactType<_FocusMarker>();
return marker?.notifier?.nearestScope ?? context.owner!.focusManager.rootScope;
}
