Stately #
A simple FSM solution for creating declarative and predictable state machines.
Designed to work with popular state management solutions to no matter what you are using you
should be able to drop this right in!



stately_core





stately_bloc



stately_notifier



stately_riverpod




To get started, you can utilize stately_notifier without any extra dependencies like so:
class CounterEvent {
const CounterEvent(this.value);

final int value;
}

class CounterValueNotifier extends StatelyChangeNotifier<CounterEvent, int> {
CounterValueNotifier(super.state);

@override
StatelyGraph<CounterEvent, int> get graph => StatelyGraph<ExampleEvent, String>(
graph: {
String: {
ExampleEvent: transition((CounterEvent event, int state) => event.value),
},
},
);
}

And then can use it with ValueListenableBuilder like so:
final counter = CounterValueNotifier(0);

/// ...

class Home extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Column(
children: [
ValueListenableBuilder(
valueListenable: counter,
builder: (ctx, state, child) {
return Text(state.toString(), style: Theme.of(context).textTheme.headlineMedium);
},
),
ElevatedButton(onPressed: () => notifier.add(IncrementEvent()), child: Text('Increment')),
],
);
}
}
copied to clipboard
That's it!
