Activity<T extends ActiveController> class

Activity : Brings shared state to your application.

activeController : controller needed for state rebuilds when an ActiveType child : is the widget intended to be rendered. onActivityStateChanged : this function is called whenever an ActiveType is updated on the state. Gets Activity inherited widget needs to be updated. The _trackId needs to be updated uniquely to allow UI rebuilds to happen, if you update with the same value a UI rebuild wont happen developerMode : this is a flag that is responsible in debug print

Example Using Timestamp


     Activity(
        BaseController(),
        onActivityStateChanged: ()=>
            DateTime.now().microsecondsSinceEpoch.toString(),
        child: TaskView(
          activeController: BaseController(),
        ),
      ),

class MyApp extends StatelessWidget {
  const MyApp({super.key});
 @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Activity Task App',
      theme: ThemeData(primarySwatch: Colors.blue),
      home: Activity(
        BaseController(),
        onActivityStateChanged: ()=>
            DateTime.now().microsecondsSinceEpoch.toString(),
        child: TaskView(
          activeController: BaseController(),
        ),
      ),
    );
  }
}
