当我尝试从本地（位于assets/images/）的Unsplash加载this image时，没有显示任何内容，也没有报告错误。当我将图像源更改为network时，图像加载完全正常（但速度较慢）。
不工作：

Container(
     decoration: BoxDecoration(
          image: DecorationImage(
             image: AssetImage("assets/images/image.jpg"),
             fit: BoxFit.cover))

作品：

Container(
     decoration: BoxDecoration(
         image: DecorationImage(
             image: NetworkImage("https://source.unsplash.com/zuueig1w8WI/"),
              fit: BoxFit.cover)),

当前正在使用Flutter Web。

编辑图像已在pubspec中。
