ReignController<T> class abstract

Base class for all state controllers in the Reign system.

Controllers manage business logic and state for your application. They automatically handle lifecycle events when used with ReignBuilder or ControllerProvider.

Example usage:

class CounterController extends ReignController<int> {
  CounterController() : super(0);

  void increment() {
    value++;
    update();
  }
}
