Flutter侧边栏实现及路由

侧边栏(抽屉)

侧边栏可以分为左侧边栏和右侧边栏，是放在Scaffold中使用的

return Scaffold(
      appBar: AppBar(
        title: const Text('Flutter Demo'),
      ),
      drawer: Drawer(
        child: Text("左侧边栏"),
      ),
      endDrawer: Drawer(
        child: Text("右侧边栏"),
      ),
);

DrawerHeader

属性	描述
decoration	设置顶部背景颜色
child	配置子元素
padding	内边距
margin	外边距

 drawer: Drawer(
        child: Column(
          children: [
            Row(
              children: [
                Expanded(
                  child: DrawerHeader(
                    child: Text("你好Flutter"),
                    decoration: BoxDecoration(
                      image: DecorationImage(
                        image: NetworkImage("https://cdn.stocksnap.io/img-thumbs/960w/ice-nature_PHKM6CXBLQ.jpg"),
                        fit: BoxFit.cover,
                      )
                    ),
                  ),
                )
              ],
            ),
            ListTile(
              leading: CircleAvatar(
                child: Icon(Icons.home)
              ),
              title: Text("我的空间"),
            ),
            //设置分割线
            Divider(),
            ListTile(
              leading: CircleAvatar(
                child: Icon(Icons.people)
              ),
              title: Text("用户中心"),
            ),
            Divider(),
            ListTile(
              leading: CircleAvatar(
                child: Icon(Icons.settings)
              ),
              title: Text("设置中心"),
            )
        ],),
      ),

UserAccountsDrawerHeader

UserAccountsDrawerHeader内对一些常用的组件进行了封装，可以帮助我们快速实现一个抽屉内的用户信息暂时，但格式固定（头像，用户名等已经固定在指定位置），如果想要实现更多样式的话可以使用上面的DrawerHeader进行自定义。

属性	描述
decoration	设置顶部背景颜色
accountName	账户名称
accountEmail	账户邮箱
currentAccountPicture	用户头像
otherAccountsPictures	用来设置当前账户其他账户头像
margin	设置边距

 drawer: Drawer(
        child: Column(
          children: [
            Row(
              children: [
                Expanded(
                  child:UserAccountsDrawerHeader(
                    accountEmail: Text("[email protected]"),
                    accountName: Text("sky"),
                    currentAccountPicture: CircleAvatar(
                      backgroundImage: NetworkImage("https://cdn.stocksnap.io/img-thumbs/960w/goose-flock_7EARMYLNXB.jpg")
                    ),
                    decoration: BoxDecoration(
                      image: DecorationImage(
                        image: NetworkImage("https://cdn.stocksnap.io/img-thumbs/960w/ice-nature_PHKM6CXBLQ.jpg"),
                        fit: BoxFit.cover
                      ),
                    ),
                    otherAccountsPictures: [
                      Image.network("https://cdn.stocksnap.io/img-thumbs/960w/flower-bloom_NZWKWLNPYX.jpg"),
                      Image.network("https://cdn.stocksnap.io/img-thumbs/960w/flower-bloom_KAKMFZ02RH.jpg"),

                    ],
                  )
                )
              ],
            ),
            ListTile(
              leading: CircleAvatar(
                child: Icon(Icons.home)
              ),
              title: Text("我的空间"),
            ),
            //设置分割线
            Divider(),
            ListTile(
              leading: CircleAvatar(
                child: Icon(Icons.people)
              ),
              title: Text("用户中心"),
            ),
            Divider(),
            ListTile(
              leading: CircleAvatar(
                child: Icon(Icons.settings)
              ),
              title: Text("设置中心"),
            )
        ],),
      ),

侧边栏路由跳转

需要注意的几点:

1. 在侧边栏点击进入相应页面然后返回时抽屉收入

Navigator.of(context).pop();

2. 路由就是在相应listtile中添加onTap()方法，然后使用方法和前面讲到的路由方法相同。

 Navigator.of(context).push(MaterialPageRoute(
        builder: (BuildContext context) {
    
    
                  return UserPage();
                }
        )
 );

drawer: Drawer(
        child: Column(
          children: [
            Row(
              children: [
                Expanded(
                    child: UserAccountsDrawerHeader(
                  accountEmail: Text("[email protected]"),
                  accountName: Text("sky"),
                  currentAccountPicture: CircleAvatar(
                      backgroundImage: NetworkImage(
                          "https://cdn.stocksnap.io/img-thumbs/960w/goose-flock_7EARMYLNXB.jpg")),
                  decoration: BoxDecoration(
                    image: DecorationImage(
                        image: NetworkImage(
                            "https://cdn.stocksnap.io/img-thumbs/960w/ice-nature_PHKM6CXBLQ.jpg"),
                        fit: BoxFit.cover),
                  ),
                  otherAccountsPictures: [
                    Image.network(
                        "https://cdn.stocksnap.io/img-thumbs/960w/flower-bloom_NZWKWLNPYX.jpg"),
                    Image.network(
                        "https://cdn.stocksnap.io/img-thumbs/960w/flower-bloom_KAKMFZ02RH.jpg"),
                  ],
                ))
              ],
            ),
            ListTile(
              leading: CircleAvatar(child: Icon(Icons.home)),
              title: Text("我的空间"),
            ),
            //设置分割线
            Divider(),
            ListTile(
              leading: CircleAvatar(child: Icon(Icons.people)),
              title: Text("用户中心"),
              //在这里设置转跳
              onTap: () {
    
    
                Navigator.of(context).pop();
                Navigator.of(context)
                    .push(MaterialPageRoute(builder: (BuildContext context) {
    
    
                  return UserPage();
                }));
              },
            ),
            Divider(),
            ListTile(
              leading: CircleAvatar(child: Icon(Icons.settings)),
              title: Text("设置中心"),
            )
          ],
        ),
      ),
