Initialization Code Missing: Another common cause can be the absence of the initialization code in your app. Ensure that Firebase is properly initialized in your project.

Dependency Mismatches: Sometimes, incompatible versions of Firebase and React Native libraries can cause such errors. Make sure that all the dependencies are updated and compatible with each other.

Steps to Fix

Verify Configuration Files:

Ensure that the configuration files (google-services.json for Android or GoogleService-Info.plist for iOS) are placed in the correct directories:
