stacked_hooks 0.2.2

Classes that help you make use of hooks when using the stacked package

Stacked Hooks

This package contains widgets that allow you to use the Flutter Hooks package with the ViewModelWidget in the stacked architecture.

HookViewModelWidget

The ViewModelWidget is an implementation of a widget class that returns a value provided by Provider as a parameter in the build function of the widget. This allows for easier consumption and use of ViewModel without boilerplate. The HookViewModelWidget allows you to use this widget and make use of Flutter Hooks inside the build function. This is very useful when you want to use TextEditing controllers and you're implementing this architecture.

// View that creates and provides the viewmodel
class HookViewModelWidgetExample extends StatelessWidget {
  const HookViewModelWidgetExample({Key key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return ViewModelBuilder<HomeViewModel>.nonReactive(
      builder: (context, model, child) => Scaffold(
          body: Center(
        child: _HookForm(),
      )),
      viewModelBuilder: () => HomeViewModel(),
    );
  }
}

// Form that makes use of the ViewModel provided above but also makes use of hooks
class _HookForm extends HookViewModelWidget<HomeViewModel> {
  @override
  Widget buildViewModelWidget(BuildContext context, HomeViewModel model) {
    var title = useTextEditingController();
    return Column(
      mainAxisSize: MainAxisSize.min,
      children: <Widget>[
        Text(model.title),
        TextField(
          controller: title,
          onChanged: model.updateTile,
        )
      ],
    );
  }
}

// ViewModel
class HomeViewModel extends BaseViewModel {
  String title = 'default';

  void updateTile(String value) {
    title = value;
    notifyListeners();
  }
}
