My Unity project is using ARCore Extensions and Firebase and I'm trying to link them to Flutter. It's been successfully connected on Android, but it's been failing on iOS for weeks.

I'm trying with both versions Unity6, 2022 and thinking it to be an error in flutter unity widget because both versions failed.

The initial error message is Framework 'ARCoreBase' not found.
To solve this, we added the ARCoreBase Framework in Pods of UnityLibrary folder to
Xcode > Runner Target > General > Frameworks, Libraries, and Embedded Content.

Then, the error is changed to Framework 'ARCoreGARsession' not found.
If ARCoreGARsession is added in the same way, it is changed to Framework 'ARCoreGeospatial' not found, and even if this sequential operation is completed, the error cannot be resolved due to the situation in which a module without Framework must be added in the end.

I expect Pods from UnityLibrary exported from flutter unity widget to be unrecognizable on Flutter (Runner). How do I fix this?
