ReactterComponent<T extends Object> class abstract

A abstract StatelessWidget class that provides ReactterProvider features, whose instance of T type defined is exposing trough render method.

class App extends ReactterComponent<AppController> {
  const App({Key? key}) : super(key: key);

  @override
  get builder => () => AppController();

  @override
  Widget render(BuildContext context, AppController inst) {
    return Text("State: ${inst.stateHook.value}");
  }
}

Use builder getter to define the instance creating method.

class App extends ReactterComponent<AppController> {
  @override
  get builder => () => AppController();
  ...
}

NOTE: If you don't use builder getter, the T instance is not created and instead tried to be found it in the nearest ancestor where it was created.

Use id getter to identify the T instance:

class App extends ReactterComponent<AppController> {
  @override
  get id => "uniqueId";
  ...
}

Use listenStates getter to define the states and with its changes rebuild the Widget tree defined in render method.

class App extends ReactterComponent<AppController> {
  @override
  get listenStates => (inst) => [inst.stateA, inst.stateB];
  ...
}

Use listenAll getter as true to listen all instance changes to rebuild the Widget tree defined in render method.

class App extends ReactterComponent<AppController> {
  @override
  get listenAll => true;
  ...
}

RECOMMENDED: Dont's use Object with constructor parameters to prevent conflicts.
