Por favor me ajudem, ja tentei de tudo, limpar todo o cache do cocoapods, limpar o cache do app, reinstalar tudo. So tenho esse problema ao usar o firebase Message e Firebase Core, mas preciso utilizar para implementar algumas solucoes.

good morning guys I managed to solve the problem, pod install was executed successfully. I just ran the flutter pub outdated command which brought up all the libraries that needed to be updated or were discontinued, updated everything and ran pod install. everything worked.

I tried the same but got this Analyzing dependencies cloud_firestore: Using Firebase SDK version '10.25.0' defined in 'firebase_core' firebase_auth: Using Firebase SDK version '10.25.0' defined in 'firebase_core' firebase_core: Using Firebase SDK version '10.25.0' defined in 'firebase_core' firebase_messaging: Using Firebase SDK version '10.25.0' defined in 'firebase_core' [!] CocoaPods could not find compatible versions for pod "google_maps_flutter_ios": In Podfile: google_maps_flutter_ios (from .symlinks/plugins/google_maps_flutter_ios/ios)

Specs satisfying the google_maps_flutter_ios (from.symlinks/plugins/google_maps_flutter_ios/ios) dependency were found, but they required a higher minimum deployment target.

[kirillnepomiluev]

I found working solution for me:

1. flutter upgrade
2. update in pubspec versions of the main libs
3. update cocoa pods by this instructions https://stackoverflow.com/questions/71013091/flutter-ios-pod-install-failed-after-upgrading-xcode-and-flutter-version/71014492#71014492
4. flutter clean
5. flutter build ios
