主要代码:
Dart
drawer: const Drawer(
child: Column(
children: [
Row(
children: [
Expanded(
flex: 1,
child: UserAccountsDrawerHeader(
accountName: Text("张三"),
accountEmail: Text("xxx@qq.com"),
currentAccountPicture: CircleAvatar(
backgroundImage: NetworkImage(
"https://www.itying.com/images/flutter/1.png"),
),
decoration: BoxDecoration(
image: DecorationImage(
image: NetworkImage(
"https://www.itying.com/images/flutter/2.png"),
fit: BoxFit.cover,
),
),
),
),
],
),
ListTile(
leading: CircleAvatar(
child: Icon(
Icons.people,
),
),
title: Text("个人中心"),
),
Divider(),
ListTile(
leading: CircleAvatar(
child: Icon(
Icons.settings,
),
),
title: Text("系统设置"),
)
],
),
),
在Drawer组件中直接写布局就行,需要在Scaffold组件下添加AppBar组件才会显示侧边栏三道杠菜单图标,不添加AppBar不显示图标,可以侧滑。
右边侧滑用:
Dart
endDrawer: Drawer(
),
