Flutter State Management #

This is not a new state management solution. It is just a couple of utility classes to make it easier to use the Flutter framework's built-in ChangeNotifier and Listenable.

Features #

• No learning curve if you already know Flutter
• Simple package base on built-in ChangeNotifier (No bloatware)

Usage #

Create your model class

class Counter extends PersistedStateNotifier<int> {
  Counter() : super(IsarKeyValue(), startState: 0);

  void increment() => persistedState = Loaded(data: data + 1);
}

Use builder to handle state changes in the UI

counter.builder(
  onLoaded: (context, data) => Text(data.toString()),
),

Or convert your existing StatelessWidget to RStatelessWidget, and StatefulWidget to RStatefulWidget and just watch the model inside the build method

class CounterText extends RStatelessWidget {
  @override
  Widget build(BuildContext context) {
    counter.watch(context); // watch must be called inside the build method
    return Text(data.toString());
  }
}
