Flutter 使用过时的包装进行颤振赢得'；Don’我不能运行我的应用程序

几个月前，我做了一个相当大的项目（2019年12月我停止了开发），但从那时起，我停止了开发项目，大约80%的开发工作要完成，最近我有了一些空闲时间来完成剩余的20%的项目。所以我决定跳回去，但似乎我再也不能运行我的代码，当时运行100%顺利。。是因为我使用的是过时的软件包吗

下面是我得到的错误：

Compiler message:

这是我在pubspec.yaml中的依赖项（我删除了所有包名：^1.00，因为我认为这会迫使它使用更高版本？如果我错了，请纠正我。）

我不想使用更新包的原因是：我必须重构我创建的大部分提供程序代码，因为我使用了ChangeNotifierProvider并将其包装在main.dart小部件中，这将占用我大量的时间。任何帮助都将不胜感激！非常感谢你

您的问题似乎是由插件缓存的\u网络\u图像引起的，您能否更改插件版本并重试，对此版本缓存的“网络”映像：^2.0.0-rc

请使用最新的软件包或切换到以前使用的较旧的颤振版本。它可以正常工作……您是否可以将

flatter doctor

的输出添加到您的问题中？3天前，我在尝试使用包含几乎相同依赖项的新flutter版本构建一个旧项目时遇到了这个问题。所以我想我仍然可以帮你…你的问题似乎是由插件缓存的网络图像引起的，你能改变插件版本并再试一次吗？我更喜欢此版本的缓存“网络”映像：^2.0.0-RCM谢谢，我会将其作为答案发布，希望您能接受。
