    Try to remove Podile.lock and rebuild the app

    UPDATE

    Sometimes problems happen due target ios platform. Try to do these steps:

    • flutter clean
    • update all dependencies to the latest version in pubspec.yml file and do flutter pub get
    • Go to your Podfile and uncomment #platform :ios, '9.0' Then change the version to 10 platform :ios, '10.0'
    • go to ios folder and throuh the terminal run command: pod repo update, pod update or pod install

    Both the packages (firebase_auth and mobile_scanner) are using GTMSessionFetcher pod internally in iOS.

    As both plugin uses different version of GTMSessionFetcher it causes conflicts, thus we are not able to compile iOS app.

    There is one open issue in firebase-ios-sdk where we can get all the updates, as of now I am also not able to found any issues, but will update here if I found anything important. Thanks.

    Update

    I found two more linked issues.

    For me Updating all the firebase dependencies to the latest version and google sign in version removed this error.

    Then, run pod install.
