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.
Features
- 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...
Usage
TODO: Include short and useful examples for package users. Add longer examples
to /example
folder.
class CounterComponent extends Component {
late int counter;
@override
void initListeners() {
// called before onLoad, use this to register the events
registerEvent(onIncrement);
registerEvent(onDecrement);
}
Future<void> onIncrement(IncrementEvent e) async {
// can be fully asynchronous
await Future.delayed(Duration(milliseconds: Random().nextInt(2000)));
counter = counter + e.value;
send(CounterUpdateEvent(counter));
}
void onDecrement(DecrementEvent e) {
// or sync, but will only be called if this exact event is sent
counter = counter - e.value;
send(CounterUpdateEvent(counter));
}
@override
void onLoad() {
// called after register listeners, use this set up your component
counter = 0;
}
@override
void onUnload() {
// called right after the listeners are unregistered
}
}
