of<T extends ChangeNotifier> method
T
of<T extends ChangeNotifier>()
Create a dependency between the calling widget and a Bilocator widget with generic type T
.
Same idea as the "of" feature of Provider.of, Theme.of, etc. For no dependency, use get.
Performs a lazy initialization if necessary. An exception is thrown if T
is not a ChangeNotifier.
or the not match found.
Implementation
T of<T extends ChangeNotifier>() {
final _BilocatorInheritedWidget<T>? inheritedWidget =
dependOnInheritedWidgetOfExactType<_BilocatorInheritedWidget<T>>();
if (inheritedWidget == null) {
throw Exception(
'BuildContext.of<T>() did not find inherited widget Bilocator<$T>(). Possible causes:\n'
' - The data was stored in the registry instead of the widget tree. To search the registry, do not use '
'BuildContext.\n\n');
}
return inheritedWidget.instance;
