浅识Flutter 基本组件Scaffold的 drawer属性 app创建头像

在项目开发中使用本地图片资源文件的步骤。

1、在项目下创建一个文件夹image

2、将本地图片放入images文件夹里

3、 在pubspec.yaml文件中声明本地图片资源文件，声明代码如下:

flutter:
	assets:
		- images/pman.png#-后面有1个空格

先找到flutter：
加入声明代码

点击 pub get 更新 无报错即可

onDetailsPressed：设置当accountName或accountEmail被点击的时所触发的回调函数

UserAccountsDrawerHeader(accountName: Text('阿大豆'),
              accountEmail:Text('[email protected]') ,
                currentAccountPicture: CircleAvatar(backgroundImage:AssetImage('images/pman.png') ,
                ),
                onDetailsPressed: (){print('其实我是阿大豆');},
              ),

效果 ：点击方框内区域 会打印出文本函数

设置 点击左上方菜单图标 就可打开侧边栏
