A new approach to business logic by having all logic be independent components. Unlike Bloc, state is not managed by sending states but by viewmodels, which are components as well.


  • Seperate your logic from your widgets.
  • Testable and easy to integrate.
  • Easy to learn

Getting started

At the top level of your app, provide a ComponentRegistry, then anywhere in your app use a ComponentBuilder with your own ComponentViewModel. Register your eventhandlers and add components in the componentregistry.

W.I.P. A proper example will follow. This is a short description...


TODO: Include short and useful examples for package users. Add longer examples to /example folder.

class CounterComponent extends Component {
  late int counter;

  void initListeners() {
    // called before onLoad, use this to register the events

  Future<void> onIncrement(IncrementEvent e) async {
    // can be fully asynchronous
    await Future.delayed(Duration(milliseconds: Random().nextInt(2000)));
    counter = counter + e.value;

  void onDecrement(DecrementEvent e) {
    // or sync, but will only be called if this exact event is sent
    counter = counter - e.value;

  void onLoad() {
    // called after register listeners, use this set up your component
    counter = 0;

  void onUnload() {
      // called right after the listeners are unregistered
