How to fix the Image inside CircleAvatar when the window is being resized in flutter web
问题
问题是，我希望即使调整窗口大小，图像也保持固定。这是代码：
CircleAvatar(
radius: 60.0,
backgroundImage: AssetImage('images/profile.png'),
),
我尝试过使用SizedBox，FittedBox，Align和居中对齐，但没有什么真正有效的。我在想是否有可能让它固定在一个位置。
英文:
The thing is I want the image to be fixed even when the window is being resized , Here's the code :
CircleAvatar(
radius: 60.0,
backgroundImage: const AssetImage('images/profile.png'),
),
I tried using SizedBox , FittedBox Align Center and nothing actually worked , I wondering if is it even possible to make it fix in a place

尝试像这样使用 Align 小部件：
Align(
alignment: Alignment.topCenter, // 将 CircleAvatar 对齐到顶部中央。
child: CircleAvatar(
radius: 50, // 半径为 50
backgroundImage: NetworkImage(
'https://cdn.pixabay.com/photo/2015/03/03/20/42/man-657869_1280.jpg'),
),
),

根据屏幕宽度使用媒体查询来更改圆形头像的半径，像这样：
CircleAvatar(
radius: MediaQuery.of(context).size.width * 0.4,
backgroundImage: const AssetImage('images/profile.png'),
),
将0.4更改为所需的任何值。
英文:
change the radius of circle avatar according to screen width using media query like this.
CircleAvatar(

你可以使用 nb_utils 包来创建响应式应用程序。要创建响应式头像，您可以使用 radius: 40.w，这样 40.w 将根据屏幕宽度来自动调整响应式效果。要进行初始化，将 nb_utils 导入到 main.dart 文件中。
void main() async {
WidgetsFlutterBinding.ensureInitialized();
await initialize();
runApp(MyApp());
}
支持的平台：
- Android
- iOS
- Windows
- Web
- Linux
- macOS
CircleAvatar(
radius: 40.w,
backgroundImage: const AssetImage('images/profile.png'),
)
您可以根据需要更改 40.w 的值。
英文:
you may use use nb_utils package to create responsive apps, To make responsive avatar you can use radius 40.w. so 40.w will be responsive according to width of screen.
initialize nb_utils in main.dart file for initializing.
void main() async {
WidgetsFlutterBinding.ensureInitialized();
await initialize();
runApp(MyApp());
}
Supported Platform
- Android
- Ios
- Windows
- Web
- Linux
- macos

我通过移除BackgroundImage并将图像裁剪成圆形而不是默认的矩形（我将其命名为"profile-modified"）来解决了问题。我使用了Image.asset作为CircleAvatar的子元素，并使用了fit: BoxFit.cover。
修改后的代码如下：
CircleAvatar(
radius: 60.0,
child: Image.asset(
'images/profile-modified.png',
fit: BoxFit.cover,
),
),
英文:
I got it fixed by removing the BackgroundImage and also cropping the image into circular instead of default rectangle (I named it as "profile-modified"). I used Image.assest as a child of CircleAvatar and using fit: BoxFit.cover .
The modified code looks this way :
CircleAvatar(
radius: 60.0,
child: Image.asset(
'images/profile-modified.png',
fit: BoxFit.cover,
),
),
