简而言之：
使用了Material 风格的widget 就需要Scaffold作为根布局

什么是Material 风格的widget，比如

AppBar
BottomAppBar
FloatingActionButton
Drawer
SnackBar
BottomSheet
BottomNavigationBar
ListTile
等等

需要Scaffold作为根布局，意为用Scaffold包裹起来即可
 

return Scaffold(
      appBar: AppBar( ),
      bottomNavigationBar: BottomNavigationBar( ),
      floatingActionButton: FloatingActionButton( ),
      drawer: Drawer(),
      .....
    );
