Actually I am trying to create a alert dialog with a icon in the title followed by the the heading the problem is whem i am using a image.network on a image whose size is 192x192 px it is working file but when I am using a image.asset on a image which has same size (192x192 px) then it gives me the error that**A RenderFlex overflowed by 337 pixels on the right.**I tried many different images with different sizes but nothing works.
下面是代码：

showDialog(
  context: context,
  builder: (build) {
    return AlertDialog(
      title: Row(children: [
        Image.asset(
          'assets/image.png',
          height: 50,
          width: 50,
          fit: BoxFit.contain,
        ),
        Text('  Alert Dialog Title.')
      ]),
      content: Text("Are You Sure Want To Proceed?"),
      actions: <Widget>[
        ElevatedButton(
          child: Text("YES"),
          onPressed: () {},
        ),
        ElevatedButton(
          child: Text("CANCEL"),
          onPressed: () {},
        ),
      ],
    );

同样得到图像。资产错误我的图像路径和pubspec. yaml文件是正确的，我检查了两次。

问题出在文本小部件上。

showDialog(
        context: context,
        builder: (build) {
          return AlertDialog(
            title: Row(children: [
              Image.asset(
                'assets/images/image.jpeg',
                height: 50,
                width: 50,
                fit: BoxFit.fitWidth,
              ),

              // wrap your long text in [Flexible] and give the Text widget [overflow: TextOverflow.ellipsis]
              Flexible(
                child: Text(
                  'Getting error A RenderFlex overflowed by 337 pixels on the right. ',
                  overflow: TextOverflow.ellipsis,
                  maxLines: 2,
                ),
              ),
            ]),
            content: Text(
                "A RenderFlex overflowed by 337 pixels on the right. I tried many different images with different sizes but nothing works. Are You Sure Want To Proceed?"),
            actions: <Widget>[
              ElevatedButton(
                child: Text("YES"),
                onPressed: () {},
              ),
              ElevatedButton(
                child: Text("CANCEL"),
                onPressed: () {},
              ),
            ],
          );
        });
