      ),
      child: Drawer(

          children: <Widget>[Column(
            children: <Widget>[
              Container(

使用Container小部件作为抽屉，然后将background image和drawer's items的堆栈作为容器的子容器。

    Scaffold(
      ...,
      drawer: Container(
      child: Stack(
        children: <Widget>[
          Image.asset("myBackgroundImage.png"),
          ListView(
            children: <Widget>[
            CircleAvater(),
            ListTile(),
            ListTile(),
            ...
            ],          
         ),    
        ],      
       ),      
      ),
     );
