o is a simple state management util to manage AppState and LocalState.

• Based on Streams
• Global singleton for AppState
• Beta

Features

• It's so bad and dumb
• StreamBuilder based helper widgets
• Previous state
• Notify state
• Hooks for easy usage
• Customizable

Local State

final (count, setCount) = useState(50);

App State

final (down, setDown) = useStore('counter', 500);

Widget

Observer(observable: observable, builder: (context, observable, value, hasData) => ...)

Dep Injector

dependencies(
        [useStore<int>('counter', 25)],
        app: const Scaffold(body: Center(child: Listener())),
      );

Service Injector

dependencies([
      //useStore<int>('counter', 25),
    ],
        app: injector(
            objects: [AuthService(keyname: 'auth')],
            functions: [],
            app: const MaterialApp(
              home: AuthView(),
            )));

Usage

App State

this isn't necessary . useStore always register an observable if there isn't any by the key . but better . in any upper widget

class App extends StatelessWidget {
  const App({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: dependencies(
        [useStore<int>('counter', 25)],
        app: const Scaffold(body: Center(child: Listener())),
      ),
    );
  }
}

and access it in any widget

class Listener extends StatelessWidget {
  const Listener({super.key});

  @override
  Widget build(BuildContext context) {
    final (down, setDown) = useStore('counter', 500);

    return Column(
      children: [
        Observer(
          observable: down,
          builder: (context, observable, value, hasData) => Text('App State : ${value.toString()}'),
        ),
        FloatingActionButton(onPressed: () {
          setDown((prev) => prev - 1);
        }),
      ],
    );
  }
}

Local State

simple

class Listener extends StatelessWidget {
  const Listener({super.key});

  @override
  Widget build(BuildContext context) {
    final (count, setCount) = useState(50);

    return Column(
      children: [
        Observer(
          observable: count,
          builder: (context, observable, value, hasData) => Text('Local State : ${value.toString()}'),
        ),
        FloatingActionButton(onPressed: () {
          setCount((prev) => prev + 1);
        }),
      ],
    );
  }
}
