flutter - 如何在保持对话框打开的同时关闭抽屉？

Question

最小代码：

void main() => runApp(MaterialApp(home: MainPage()));

class MainPage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(),
      drawer: MyDrawer(),
    );
  }
}

class MyDrawer extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Drawer(
      child: RaisedButton(
        onPressed: () {
          // Close the Drawer, not the Dialog. 
          Timer(Duration(seconds: 2), () => Navigator.of(context, rootNavigator: true).pop());

          // Show the Dialog and keep it in opened state. 
          showDialog(
            context: context,
            builder: (_) => AlertDialog(title: Text('FooDialog')),
          );
        },
        child: Text('Show Dialog'),
      ),
    );
  }
}

按下按钮时，我正在显示对话框，2 秒后我想关闭对话框，Drawer同时保持Dialog在屏幕上打开。Timer为此，我正在使用rootNavigator. Navigator但是，我的对话被解雇了。

GlobalKey<DrawerControllerState>除了使用东西之外，还有什么办法可以关闭抽屉吗？

class MyDrawer extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Drawer(
      child: RaisedButton(
        onPressed: () {
          // Close the Drawer, not the Dialog. 
          Timer(Duration(seconds: 2), () => Scaffold.of(context).openEndDrawer());

          // Show the Dialog and keep it in opened state. 
          showDialog(
            context: context,
            builder: (_) => AlertDialog(title: Text('FooDialog')),
          );
        },
       child: Text('Show Dialog'),
     ),
   );
  }
}
