Firebase – GoogleService-Info.plist file not found and clientId was not provided programmatically

I tried adding firebase to my flutter project using fluttefire command line tool. I am using Google Authentication service from firebase and calling SignIn function, it gives the following error. The ios folder has GoogleService-Info.plist file.

Unhandled Exception: PlatformException(missing-config, GoogleService-Info.plist file not found and clientId was not provided programmatically., null, null)
    #0      StandardMethodCodec.decodeEnvelope (package:flutter/src/services/message_codecs.dart:607:7)

    The FlutterFire command line tool generates a Dart file, so you don’t need a GoogleService-Info.plist. Inserting a GoogleService-Info.plist although using the Command Line tool is redundant. However, you must also specify the generated options when initializing:

    Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform)

    Using DefaultFirebaseOptions is the new way for using Firebase with Flutter and the manual insertion of the configuration files is the old way.

    EDIT: I didn’t understand that this problem is about the GoogleSignIn plugin (I did not really read the stack trace 😅). In this case, the error is exactly the same as in the error message. You have not specified a client id:

    GoogleSignIn(clientId: DefaultFirebaseOptions.currentPlatform.iosClientId).signIn()

    EDIT:
    Yes, the new version of flutterfire also generates the corresponding files such as GoogleService-Info.plist, but you don’t need these files anymore since the parameter clientId exists in the GoogleSignIn plugin.

    Someone posted that issues on github.
    https://github.com/flutter/flutter/issues/96248

    And they said.

    google_sign_in plugin currently doesn’t support dart-only
    initialization and for mean time, you’ll need to fallback on manual
    installation.

    31/Aug/2022, I still face the same problem

    Moving GoogleService-Info.plist file to the Runner folder solved it for me.
