我尝试重新创建项目并将所有源文件复制到新的项目文件夹中，但没有解决问题.

I tried to recreate the project and copied all the source files to the new project folder but it does not resolve the issue.

推荐答案

这个解决方案对我有用.

This solution worked for me.

1. 打开 ios/Runner.xcworkspace 在项目中选择Runner项目导航器侧边栏.
2. 在主视图中，选择 Runner 目标，然后选择 Build Phases 选项卡.
3. 展开 Embed Frameworks 阶段并从嵌入式框架列表.
4. 点击 - 从列表中移除 Flutter.framework(一定要保留应用框架).
