View class abstract

The View represents a StatefulWidget. The View is typically a page or screen in the application. However, a View can be any StatefulWidget. The View must have a State, and that State should be of type ViewState<MyView, MyController>.

If a RouteObserver is given to the View, it is used to register its Controller as a subscriber, which provides the ability to listen to push and pop route events.

  class CounterPage extends View {
    CounterPage({RouteObserver observer, Key key}): super(routeObserver: routeObserver, key: key);
    @override
    // Dependencies can be injected here
    State<StatefulWidget> createState() => CounterState(Controller());
  }
