Question

我正在开发应用程序，并且一切都按计划进行，然后我将内容升级了到最新版本。

我尝试过颤抖的医生-v ，一切看起来都好。

这是我尝试构建应用程序时收到的错误消息：

Compiler message:

Answer 1

Flutter似乎在this commit中添加了DecoderCallback，现在它是load函数的必需参数。查看您使用的cached_network_image依赖项，此问题已在其README.md中指出：

如果遇到以下错误之一，请升级到2.0.0-rc。

因此，您可以通过升级cached_network_image中的pubspec.yml来解决此问题。

Answer 2

我认为问题出在cached_network_image上。查看文档。我相信您需要使用此版本- cached_network_image：^ 2.0.0-rc

升级后无法在Flutter 1.12.13 + hotfix.5中构建我的应用
