Unhandled Exception: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiExceptio-CodePudding

I'm trying to make google login with flutter app, and I got this error. I've already get and put SHA-1 key to OAuth and Firebase and set google-services.json file under app directory. But I still got same problem.

 E/flutter (12401): [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null, null)

This is how I set.

GCP OAuth

Firebase setting - I filled all blanks

and I don't know which clientId has to be on this area.

which clientId has to be on this area?

I got 4 clientId because I already used google clientId to make django web login with google

Step 1 : Add this dependency into your pubsec file

firebase: ^9.0.2
  firebase_core: ^1.2.1
  firebase_database: ^7.1.0
  firebase_auth: ^1.2.0
  font_awesome_flutter: ^9.0.0
  google_sign_in: ^5.0.3

Step : 2 Create a new dart file and paste this code

import 'package:firebase_auth/firebase_auth.dart';
import 'package:google_sign_in/google_sign_in.dart';

class FirebaseService {
  final FirebaseAuth _auth = FirebaseAuth.instance;
  final GoogleSignIn _googleSignIn = GoogleSignIn();

  Future<String?> signInwithGoogle() async {
    try {
      final GoogleSignInAccount? googleSignInAccount =
          await _googleSignIn.signIn();
      final GoogleSignInAuthentication googleSignInAuthentication =
          await googleSignInAccount!.authentication;
      final AuthCredential credential = GoogleAuthProvider.credential(
        accessToken: googleSignInAuthentication.accessToken,
        idToken: googleSignInAuthentication.idToken,
      );
      await _auth.signInWithCredential(credential);
    } on FirebaseAuthException catch (e) {
      print(e.message);
      throw e;
    }
  }

  Future<void> signOutFromGoogle() async{
    await _googleSignIn.signOut();
    await _auth.signOut();
  }
}

Step 3: call sign in with google function:

Enable Google sign in Firebase Add your SHA 1 key into Firebase Project
