问题描述
iOS上的抖动问题 在XCode中，某些库（SharedPreferences，Apple登录）显示错误：
No type or protocol named 'FlutterPluginRegistrar'
我已经尝试过：清理干净，pod更新，清理pub-cache并重新安装所有库，唯一没有做的就是删除ios项目的pod文件夹（我做了一次，然后我可以无法恢复该项目）

解决方法
我已经为此苦苦挣扎了一段时间，我发现来自 here 的 eleomilagrosa 的解决方案有效：
I found out that the ios/Flutter/Flutter.framework got corrupted the files were all empty or blank.
to fix it,just copy existing ios/Flutter/Flutter.framework from other working Flutter projects you have.
then overwrite the corrupted ios/Flutter/Flutter.framework then build again
Reason:
Flutter.framework got corrupted.
How to identify if your Flutter.framework got corrupted?
open ios/Flutter/Flutter.framework/Headers/Flutter.h if this file is empty or blank.
