五、DrawerHeader的源码

const DrawerHeader({
    Key key,
    this.decoration,//header区域的背景
    this.margin = const EdgeInsets.only(bottom: 8.0),//外边距
    this.padding = const EdgeInsets.fromLTRB(16.0, 16.0, 16.0, 8.0),//内边距
    this.duration = const Duration(milliseconds: 250),//decoration背景发生变化时动画时间
    this.curve = Curves.fastOutSlowIn,//decoration背景发生curve曲线变化
    @required this.child,
  }) : super(key: key);

六、DrawerHeader属性介绍

Divider分割线组件

return MaterialApp(
      home: Scaffold(
          appBar: AppBar(
            title: Text("Drawer学习"),
