Question

我是新手，我正在开发一个可通过Image.network显示一长串imageListView的应用程序。一切都在运行，但是非常频繁且绝对是随机的（即使我滚动得很慢），也会出现此错误：

I/flutter (10990): EXCEPTION CAUGHT BY IMAGE RESOURCE SERVICE 
I/flutter (10990): The following HttpException was thrown resolving an image codec:
I/flutter (10990): Connection closed before full header was received, uri =
I/flutter (10990): http://www.attilofficina.altervista.org/phpbackend/JOB/000004/mockup/000004_017.jpg
I/flutter (10990): 
I/flutter (10990): When the exception was thrown, this was the stack:
I/flutter (10990): #0      NetworkImage._loadAsync (package:flutter/src/painting/image_provider.dart:525:41)
I/flutter (10990): <asynchronous suspension>.

那些图像被跳过了！

有没有办法处理此错误并强制重新加载丢失的那些图像？预先特别感谢

我也尝试使用分页的listView，一次加载的页面数最少，但这无法解决，并且错误总是随机返回。

Answer 1

我遇到了完全相同的问题，却始终无法找出问题的原因。我最终使用了Cached network image库，该库解决了我的图像加载问题。

Answer 2

可能是因为widget在widget树中被重用，从而中断了HTTP请求。然后，您可以在 FutureBuilder 或 Image 小部件中使用密钥。
