ReactterHook class abstract

Provides the functionality of ReactterHookManager.

Depends on a ReactterHookManager to listen this hook

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

class UseToggle extends ReactterHook {
  late final _state = UseState(false, this);

  bool get value => _state.value;

  UseToggle(
    bool initial,
    [ReactterContext? context],
  ): super(context) {
    _state.value = initial;
  }

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

and use it like this:

class AppContext extends ReactterContext {
  late final state = UseToggle(false, this);

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

    state.toggle();

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