Flutter NSException: Configuration fails. It may be caused by an invalid GOOGLE_APP_ID in GoogleService-Info.plist or set in the customized options

Issue

GoogleService-Info.plist file is added via Add Files to "Runner" option. So, it is in the Runner directory.

• I had already checked lots of stack overflow answer but unable to figure out the issue.

• I also recheck GOOGLE_APP_ID in GoogleService-Info.plist

• There is no issue in GoogleService-Info.plist configuration.

• I had also added the CFBundleURLTypes attributes below into the [my_project]/ios/Runner/Info.plist file.

  CFBundleURLTypes – CFBundleTypeRole – Editor – CFBundleURLSchemes –com.googleusercontent.apps.861823949799-vc35cprkp249096uujjn0vvnmcvjppkn

Solution

Finally resolved!

Simply, Configure the GoogleService-Info.plist and GoogleService.json according to its platform like:

// config acc to platform
final FirebaseOptions firebaseOptions = (Platform.isIOS || Platform.isMacOS)
    ? const FirebaseOptions(
        googleAppID: '1:926446789922:ios:e1628wrtecf870f0717b',
        gcmSenderID: '2564624562546',
        apiKey: 'AIzaSyChk3KEG7QYrs4kQfgNxBTbwerwrfCAdgg',
        projectID: 'project-23f',
        storageBucket: 'gs://project-23f.appspot.com',
        databaseURL: 'https://project-23f.firebaseio.com/',
      )
    : const FirebaseOptions(
        googleAppID: '1:926446789922:android:056bd6d9f0717b',
        gcmSenderID: '2564624562546',
        apiKey: 'AIzaSyDBq2tJ82wO0RKzfsguGCp7e6uh3Ko',
        projectID: 'project-23f',
        storageBucket: 'gs://project-23f.appspot.com',
        databaseURL: 'https://project-23f.firebaseio.com/',
      );

final FirebaseApp app =
    await FirebaseApp.configure(name: 'test', options: firebaseOptions);
