最近在看 Flutter 的知识，于是去网上找了几个项目开源的项目在本地跑跑。结果在跑 https://github.com/Sky24n/flutter_wanandroid.git 这个好项目的时候，就出现了启动的错误。

错误的内容

Invalid plugin specification.

Invalid "macos" plugin specification.

目测应该是版本什么不正确导致的问题。切换下版本就可以了。

如果你还看到了这个错误

Compiler message:

将cached_network_image的版本号升级到2.0.0-rc

到这里，这个项目就可以启动起来了啦。

顺便记录一下 Flutter 进行版本的切换操作
