class RxPage extends StatefulWidget {
  @override

}

class _RxPageState extends State<RxPage> {
  final _counter = Rx<int>(0); // create an observable

  @override
  void dispose() {
    _counter.close(); // You must call to close when you don't need the observable any more
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: RxBuilder(
          (_) => Text("${_counter.value}"),
