ReactterHook class abstract

An abstract-class that provides the functionality of ReactterState.

This is an example of how to create a custom hook:

class UseToggle extends ReactterHook {
  final $ = ReactterHook.$register;
  final _state = UseState(false);

  bool get value => _state.value;

  UseToggle(bool initial) {
    _state.value = initial;
  }

  void toggle() => _state.value = !_state.value;
}

IMPORTANT: All ReactterHook must be registered using the final $ variable.:

and use it, like so:

class AppController {
  final state = UseToggle(false);

  UserContext() {
    print('initial value: ${state.value}');

    state.toggle();

    print('toggle value: ${state.value}');
  }
}
