ld: 迁移项目后未找到 Flutter 框架

Question

尝试在 Xcode 中构建 Flutter 应用时收到此错误消息：

ld: framework not found Flutter
clang: error: linker command failed with exit code 1 (use -v to see invocation)

在阅读出现类似错误的帖子时，建议的修复方法是将 Flutter.framework 文件添加到项目中，但是本指南中概述的步骤涉及删除此文件：

当我将App.framework 和Flutter.framework 文件添加回我的应用程序并尝试在VS Code 中使用flutter build ios 时，我收到一条错误消息，告诉我要迁移我的项目并带有指向上述指南的链接。所以看起来这两种解决方案都不起作用。

这是flutter doctor --v的输出：
