在颤动中添加抽屉宽度

Question

我希望能够增加这个抽屉的宽度，因为它在打开时占据了太多的屏幕，我想稍微减小宽度，这可能吗？我该怎么做？

这是我的脚手架

Widget build(BuildContext context) {
return new Scaffold(
  appBar: new AppBar(
    title: new Text("App Name"),
    centerTitle: true,
  ),
  body: new Center(
  ),

  drawer: Drawer(
  child: ListView(
      padding: EdgeInsets.zero,
      children: <Widget>[
      UserAccountsDrawerHeader(
        accountName: Text('Test123') ,
        accountEmail: Text('[email protected]'),
        currentAccountPicture: Image.network('https://images-wixmp-ed30a86b8c4ca887773594c2.wixmp.com/f/a89c3e38-b6f3-48a0-9f9e-df9a0129fb93/daghh5x-4a77b3ec-fd4f-4d17-9f84-5963a8cb5c03.png?token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJ1cm46YXBwOjdlMGQxODg5ODIyNjQzNzNhNWYwZDQxNWVhMGQyNmUwIiwiaXNzIjoidXJuOmFwcDo3ZTBkMTg4OTgyMjY0MzczYTVmMGQ0MTVlYTBkMjZlMCIsIm9iaiI6W1t7InBhdGgiOiJcL2ZcL2E4OWMzZTM4LWI2ZjMtNDhhMC05ZjllLWRmOWEwMTI5ZmI5M1wvZGFnaGg1eC00YTc3YjNlYy1mZDRmLTRkMTctOWY4NC01OTYzYThjYjVjMDMucG5nIn1dXSwiYXVkIjpbInVybjpzZXJ2aWNlOmZpbGUuZG93bmxvYWQiXX0.dWTFMrwnbAbj5TtUp9U_vQsohW7MnkRPymzR5wZQoV8'),
        ),

        ListTile(

        ),
      ],
    ),
  ),
);

Answer 1

将 Drawer 小部件包裹在 Container 小部件内，并将宽度参数传递给 Container。

drawer: Container(
      width: 50,
      child: Drawer(
        child: ListView(
          padding: EdgeInsets.zero,
          children: <Widget>[
            UserAccountsDrawerHeader(
              accountName: Text('Test123'),
              accountEmail: Text('[email protected]'),
              currentAccountPicture: Image.network(
                  'https://images-wixmp-ed30a86b8c4ca887773594c2.wixmp.com/f/a89c3e38-b6f3-48a0-9f9e-df9a0129fb93/daghh5x-4a77b3ec-fd4f-4d17-9f84-5963a8cb5c03.png?token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJ1cm46YXBwOjdlMGQxODg5ODIyNjQzNzNhNWYwZDQxNWVhMGQyNmUwIiwiaXNzIjoidXJuOmFwcDo3ZTBkMTg4OTgyMjY0MzczYTVmMGQ0MTVlYTBkMjZlMCIsIm9iaiI6W1t7InBhdGgiOiJcL2ZcL2E4OWMzZTM4LWI2ZjMtNDhhMC05ZjllLWRmOWEwMTI5ZmI5M1wvZGFnaGg1eC00YTc3YjNlYy1mZDRmLTRkMTctOWY4NC01OTYzYThjYjVjMDMucG5nIn1dXSwiYXVkIjpbInVybjpzZXJ2aWNlOmZpbGUuZG93bmxvYWQiXX0.dWTFMrwnbAbj5TtUp9U_vQsohW7MnkRPymzR5wZQoV8'),
            ),
            ListTile(
              title: Text('data'),
            ),
          ],
        ),
      ),
    ),

Answer 2

这是另一个示例，为抽屉提供宽度。

return SizedBox(
  width: MediaQuery.of(context).size.width * 0.75, // 75% of screen will be occupied
  child: Drawer(
    
  ),
);

谢谢你。

Answer 3

这个方法尝试一次。

drawer: Container(
width: MediaQuery.of(context).size.width * 0.5,
child: Drawer()
),

Answer 4

之前

之后

支架

Drawer

与

Container

或

Sizeable

小部件

Container(
          width: 125,
          child: Drawer(
            child: ListView(
              // Important: Remove any padding from the ListView.
              padding: EdgeInsets.zero,
              children: [
                const DrawerHeader(
                  decoration: BoxDecoration(
                    color: Colors.blue,
                  ),
                  child: Text('Drawer Header'),
                ),
                ListTile(
                  title: const Text('google.com'),
                  onTap: () {
                    widget._controller!.loadUrl(
                        urlRequest: URLRequest(url: Uri.parse("www.google.com")));

                    // Update the state of the app.
                    // ...
                  },
                ),
                ListTile(
                  title: const Text('yahoo.com'),
                  onTap: () {
                    widget._controller!.loadUrl(
                        urlRequest: URLRequest(url: Uri.parse("www.yahoo.com")));
                    // ...
                  },
                ),
              ],
            ),
          ),
        )

Answer 5

1. 使用 flutter_screenutil

   应用动态宽度

2. 尝试使用下面的代码片段

Container(
width: MediaQuery.of(context).size.width * 0.3, // Container will occupy 
30% of total width
child: Drawer(),
);

Answer 6

对我有用：

返回支架( 抽屉: 抽屉( 宽度：ihmParams.menuWidth， 孩子：左菜单（ 关闭菜单：真， ), ),

代码
