Flutter issues on ios In XCode, Some library (SharedPreferences, Apple Sign-In) is showing errors:

No type or protocol named 'FlutterPluginRegistrar'

I already tried with: flutter clean, pod update, I cleaned pub-cache and reinstalled all the libraries, the only thing I did not do is delete the pod folder of the ios project (I did it once and then I could not recover the project)

I've struggled with this for some time, and I've found that eleomilagrosa's solution from here works:

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.

for the iOS side, you can also try to change the iOS bundle identifier,

111

Then it will compile from Zero.
