of method

@override T of(BuildContext context, { bool defaultToGlobal = false, })

Obtain the state from the nearest InheritedWidget inserted using inherited.

The BuildContext used, will be registered so that when this Injected model emits a notification, the Element related the the BuildContext will rebuild.

If you want to obtain the state without registering use the call method.

myModel.of(context); // Will return the state and register the BuildContext.
myModel(context); // Will return the Injected model and do not register the BuildContext.

Implementation

@override
T of(BuildContext context, {bool defaultToGlobal = false}) {
  final _inheritedInjected =
      context.dependOnInheritedWidgetOfExactType<_InheritedInjected<T>>();

  if (_inheritedInjected != null) {
    if (_inheritedInjected.globalInjected == this) {
      _inheritedInjected.injected.initialize();
      return _inheritedInjected.injected.snapValue.state;
    } else {
      return of(
        _inheritedInjected.context,
        defaultToGlobal: defaultToGlobal,
      );
    }
  }
  if (defaultToGlobal) {
    return snapState.state;
  }
  throw Exception(
    'No Parent InheritedWidget of type $T is found\n'
    'If you pushed to new route use reInherited method to provide the state '
    'to the new route',
  );
  // return null;
