android - Firebase Unity - Failed to read Firebase options from the app's resources - Stack Overflow

For some context to the project's structure, it's a Unity game that's within a Flutter project. This was achieved using the flutter-unity-widget. So far I have been setting up Firebase Analytics as a Unity project.

Now onto the issue. I have been getting the error report:

Failed to read Firebase options from the app's resources. Either make sure google-services.json is included in your build or specify options explicitly.

The FirebaseApp.androidlib is located within the unityLibrary and it has the google-services.xml file inside. google-services.xml in FirebaseApp.androidlib

I have also tried just manually inputting the file into the app's root. Like so: google-services.json in android root

For my current attempt, I have set the AppOptions for the FirebaseApp explicitly hoping it would fix the issue as stated but it's still returning the error.

There could be the possibility of me not setting up proguard or the build gradle properly.

Proguard:
