22、Scaffold属性 抽屉菜单Drawer

在Scaffold组件里面传入drawer参数可以定义左侧边栏，传入endDrawer可以定义右侧边栏。侧边栏默 认是隐藏的，我们可以通过手指滑动显示侧边栏，也可以通过点击按钮显示侧边栏。  

class MyFlutterApp extends StatelessWidget {
  const MyFlutterApp({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text("Flutter App")),
      drawer: const Drawer(
        child: Text("左侧侧边栏"),
      ),
      endDrawer: const Drawer(
         child: Text("左侧侧边栏"),
      ),
    );
  }
}

Flutter DrawerHeader

常见属性：

class MyFlutterApp extends StatelessWidget {
  const MyFlutterApp({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text("Flutter App")),
      drawer: const Drawer(
          child: Column(
        children: [
          Row(
            children: [
              Expanded(
                flex: 1,
                child: DrawerHeader(
                  decoration: BoxDecoration(  //头部
                      color: Colors.red, //背景颜色
                      image: DecorationImage(
                          image: NetworkImage("https://www.itying.com/images/flutter/3.png"), 
                           fit: BoxFit.cover) //背景图片(不是圆形)
                      ),
                  child: Text("头部")
                ),
              )
            ],
          ),

          //  SizedBox(height: 60,), //顶部间距
          // DrawerHeader(
          //   decoration: BoxDecoration(
          //     color: Colors.red //背景颜色
          //   ),
          //   child: Text("头部"),
          // ),
          ListTile(
            leading: CircleAvatar(
              child: Icon(Icons.people),
            ),
            title: Text("个人中心"),
          ),
          ListTile(
            leading: CircleAvatar(
              child: Icon(Icons.toll),
            ),
            title: Text("设置"),
          )
        ],
      )),
      endDrawer: const Drawer(
        child: Text("右侧侧边栏"),
      ),
    );
  }
}

      drawer: const Drawer(
          child: Column(
        children: [
          Row(
