GeneratedPluginRegistrant.h:8:9: 'Flutter/Flutter.h' file not found

Question

when I compile my flutter(version 2.0.1) project using this command in macOS Catalina 10.15.7 in GitHub Actions(today I found in my local macOS machine have the same issue and struggle for days):

bundle exec fastlane beta

it shows this error:

Answer 1

I tried everything I could do, but I ended up re-creating ios directory.

My 2 projects had the same settings, but only 1 project made this issue.

Anyway, this is what I did finally.

rm -rf ios
flutter create -i swift .

Of course, it's very annoying to reset flavors and other things.

Note: by performing the above steps will lose all native ios setup. In my case I was getting this error in the demo project I did this.
