BaseScreenState<T extends BaseScreen, S extends BaseStoreMixin> class Null safety

BaseScreenState is a base class for all screen states in the app.

  • It provides the store.
  • AutomaticKeepAliveClientMixin is used to keep the screen alive when the user navigates to another screen.
  • It also provides the initState method to initialize the store instance.
  • It also provides the build method to build the screen.
  • Every screen state should extend this class.
  • BaseScreenState is a stateful widget.
  • Example:
class _MyHomePageState extends BaseScreenState<MyHomePage, MainStore> {
    @override
    Widget build(BuildContext context) {
      super.build(context);
      return Scaffold(
        appBar: AppBar(),
        body: Container()
     );
   }
}
