  final String title;

  @override

}

class _MyHomePageController extends State<MyHomePage> {
  int counter = 0;

  void incrementCounter() {
    setState(() {
      counter++;
    });
  }

  @override
  Widget build(BuildContext context) => _MyHomePageView(this);
}

class _MyHomePageView
    extends StatefulWidgetView<MyHomePage, _MyHomePageController> {
  const _MyHomePageView(_MyHomePageController controller, {Key key})
      : super(controller, key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            Text(

            ),
            Text(
              '${controller.counter}',
              style: Theme.of(context).textTheme.headline4,
            ),
          ],
        ),
