I'm trying to build my Flutter app for iOS, and the process is failing due to a CocoaPods dependency conflict involving GoogleUtilities/Environment. It seems different Firebase packages are requesting incompatible versions of this pod.

🔧 My Dependencies

pubspec.yaml (relevant)

firebase_core: 2.32.0firebase_messaging: 14.9.4google_sign_in: 6.1.5

❌ Error from pod install

[!] CocoaPods could not find compatible versions for pod "GoogleUtilities/Environment":In Podfile:firebase_core (2.32.0) -> Firebase/CoreOnly (= 10.25.0) ->FirebaseCore (= 10.25.0) -> GoogleUtilities/Environment (~> 7.12)

Has anyone found a compatible set of plugin versions for Firebase that avoids this conflict on iOS?

Is there a recommended way to resolve version mismatches for GoogleUtilities/Environment when multiple Firebase plugins are involved?

Thanks in advance for any help! 🙏

I ran flutter clean followed by flutter pub get to reset the build environment.

I downgraded firebase_messaging to earlier versions like 14.9.1 and 14.9.0 to see if they depended on compatible pod versions.

I ran flutterfire configure to regenerate my Firebase iOS setup and ensure it's using the correct versions.

I manually checked the Firebase iOS SDK versions and their transitive CocoaPods dependencies to identify where the conflict is.

I tried letting pod install resolve automatically without a Podfile.lock but still got the same error.

I expected flutter build ios (or pod install) to complete successfully and resolve all Firebase-related pod dependencies, so I could proceed with building and running the app on an iOS simulator or device.
