Flutter 处理网络图像加载错误

我的应用程序正在显示大量图像，一些URL可能无效

这是我用来显示图像的代码：

（我使用

缓存的\u网络\u图像

插件）

CachedNetworkImage(
imageUrl:images.first，
适合：BoxFit.cover，
占位符：（上下文，url）=>中心(
子对象：CircularProgressIndicator（），
),
errorWidget：（上下文、url、错误）=>Center(
子：常量图标（Icons.error）
)
)

基本上，会引发以下错误：

E/flutter (28425): [ERROR:flutter/lib/ui/painting/codec.cc(97)] Failed decoding image. Data is either invalid, or it is encoded using an unsupported format.

这次抛出的错误示例如下：

问题是，在发布模式下，如果出现任何错误，我会强制关闭应用程序，因此我需要处理它们

我如何处理这种类型的错误
