Flutter Custom Drawer Icon (use keys)

drawer_icon.dart

class _HomePageState extends State<HomePage> {
  final GlobalKey<ScaffoldState> _scaffoldKey = new GlobalKey<ScaffoldState>();

  @override
  Widget build(BuildContext context) {
    return new Scaffold(
        key: _scaffoldKey,
        appBar: new AppBar(
            title: new Text("App"),
            leading: new IconButton(
                icon: new Icon(Icons.apps),
                onPressed: () => _scaffoldKey.currentState.openDrawer())),
        drawer: new Drawer());
  }
}
