Xcode 11.2、Catalina和Flutter v1.9.1+hotfix.6之后未解决的v1.9.1+hotfix.6构建错误

Question

升级后，我使用Vcode的旧颤振项目不能再构建了，有大量错误，如下所示。我试过：

删除Podfile.lock

• pod缓存的

1. 清除--所有
2. rm -rf -rf -rf Pods
3. pod deintegrate
4. pod setup

一周都没有解决这个问题。非常感谢你！

Answer 1

您可以尝试在应用程序的根文件夹中调用flutter clean。

Answer 2

您的项目已损坏。我解决了它通过创建新的颤振项目，然后复制源代码，.yaml文件，lib文件夹和assets，然后重建项目。

Answer 3

你试过在你的ios文件夹上更新pod吗？

pod update

然后再运行你的项目。
