DeexConsumer<S extends DeexStore> class

A widget that listens to a DeexStore and rebuilds when the state changes. It combines both a builder and a listener callback.

Example:

class CounterStore extends DeexStore {
  int _count = 0;

  int get count => _count;

  void increment() {
    _count++;
    update();
  }
}

class CounterPage extends StatelessWidget {
  final CounterStore store = CounterStore();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('Counter')),
      body: DeexConsumer<CounterStore>(
        store: store,
        listener: (context, store) {
          // You can show a snack bar or perform other side effects here
          ScaffoldMessenger.of(context).showSnackBar(
            SnackBar(content: Text('Counter updated: ${store.count}')),
          );
        },
        builder: (context, store) {
          return Center(
            child: Column(
              mainAxisAlignment: MainAxisAlignment.center,
              children: [
                Text('You have pushed the button this many times:'),
                Text('${store.count}', style: Theme.of(context).textTheme.headline4),
              ],
            ),
          );
        },
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: store.increment,
        tooltip: 'Increment',
        child: Icon(Icons.add),
      ),
    );
  }
}
