The line where is going to crash:

GoogleSignInAccount googleUser = await _googleSignIn.signIn();

What have I tried:

  1. I've generated my SH1 key with this command keytool -list -v \ -alias androiddebugkey -keystore ~/.android/debug.keystore
  2. Adding SH1 encryption into console.firebase.google.com
  3. Re-downloading the google-service.json
  4. Copying the debug.keystore from .android to MyProject/android
  5. Run in debug and release

  6. Adding into android/build.gradle those lines:

    • classpath 'com.android.tools.build:gradle:3.2.1'
    • classpath 'com.google.gms:google-services:4.2.0'

  7. Adding into android/app/build.gradle this lines:

    • implementation 'com.google.firebase:firebase-core:16.0.9' under dependencies
    • apply plugin: 'com.google.gms.google-services' on the end of the file.
  8. Creating a file named release-signing.properties under my project folder with those lines in it.
    • storeFile=debug.keystore
    • keyAlias=androiddebugkey
    • storePassword=android
    • keyPassword=android

Also, I've searched in ALL StackOverflow question that I could found for this question, and none of them was useful for me.

My pubspec.yaml:

firebase_core: ^0.4.0+1
firebase_analytics: ^3.0.1

cloud_firestore: ^0.11.0+2

firebase_auth: ^0.11.1
google_sign_in: ^4.0.1+3

rxdart: ^0.22.0

Auth class:

class AuthService {
  final GoogleSignIn _googleSignIn = GoogleSignIn();
  final FirebaseAuth _auth = FirebaseAuth.instance;
  final Firestore _db = Firestore.instance;

  Observable<FirebaseUser> user;
  Observable<Map<String, dynamic>> profile;
  PublishSubject loading = PublishSubject();

  AuthService() {
    user = Observable(_auth.onAuthStateChanged);
    profile = user.switchMap((FirebaseUser user) {
      if (user != null) {
        return _db
            .collection('user')
            .document(user.uid)
            .snapshots()
            .map((snap) => snap.data);
      } else {
        return Observable.just({});
      }
    });
  }

  Future<FirebaseUser> googleSignIn() async {
    loading.add(true);
    GoogleSignInAccount googleUser = await _googleSignIn.signIn();
    GoogleSignInAuthentication googleAuth = await googleUser.authentication;
    // FirebaseUser user = await _auth.signInWithGoogle(
        // accessToken: googleAuth.accessToken, idToken: googleAuth.idToken);
    final AuthCredential credential = GoogleAuthProvider.getCredential(
      accessToken: googleAuth.accessToken,
      idToken: googleAuth.idToken,
    );
    FirebaseUser user = await _auth.signInWithCredential(credential);
    updateUserData(user);
    print("Sign in" + user.displayName);

    loading.add(false);

    return user;
  }
}

Main class:

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  AuthService authService = AuthService();

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blueGrey,
      ),
      home: Scaffold(
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              MaterialButton(
                child: Text("Log in with Google"),
                color: Colors.blueGrey,
                textColor: Colors.deepOrange,
                onPressed: () => authService.googleSignIn(),
              ),
              MaterialButton(
                child: Text("LogOut"),
                color: Colors.redAccent,
                textColor: Colors.purple,
                onPressed: () => authService.signOut(),
              ),
            ],
          ),
        ),
      ),
    );
  }
}

Now if any of you could point me in the right direction I would be very grateful.

Here are some stackoverflow links that I've tried already:

  1. Google sign in doesn't work after release of flutter app
  2. Flutter and google_sign_in plugin: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null)
  3. Google Sign In error 12500

I didn't have luck with any of them, please let me know what do you think and how can I fix it.

    After I'm pressing the "Log in with Google" button I will open a pop-up where I need to select my google account. I will receive this error right after I will press on my google account. Commented May 17, 2019 at 14:58
  • I've added on the question the line where is going to crash. Commented May 17, 2019 at 15:07
  • Have you checked the logcat for a more detailed error message? Since it's a platform exception, it's failing in the platform side, so you'll sometimes find error messages in the android or iOS logs that you won't find in flutter Commented May 17, 2019 at 15:58

Reset to default

The OP, @Mircea, specifically mentioned error 12500. This is how I overcame that error:

I have spent the last few days running into the same problem. I refactored my code dozens of times, added break points, reset the SHA-1, SHA-256 and did just about every other 'code' based solution I could find. I was constantly running into the error:

E/flutter (11935): [ERROR:flutter/lib/ui/ui_dart_state.cc(148)] Unhandled Exception: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 12500: , null)

I was losing my mind so I decided to start with fresh eyes and move slowly through solutions one more time. I noticed an obscure post nestled deep in a thread that mentioned something about having a support email. It was not until I added a said support email that things "magically" started working. I've attached a screenshot below of the Firebase settings for my project.

It's not work with me
Yes, for 12500 error code, this is working... Thanks.
Google sign-in is working with my physical devices perfectly, but with the emulator, it shows exception 12500. what I am missing?
nope not true. already have the email address.
the support email is configured in two different places, first: in the app upon configuration, second: on enabled google login (this second one was in my case the error 12500)

In my case, I have not enabled Google Sign In method.

You need to complete "Oauth consent screen"

I went to this page (https://console.developers.google.com/apis/credentials) Do not forget to select your project on the list (top left). Then go on "Oauth consent screen"

I filled the application logo and the application homepage link and aplication privacy policy link (with the project.firebaseapp.com) and saved.

enter image description here

Now it's working, I can login.

This must be explained in the documentation. People are going to be crazy and to don't try flutter with this kind of lack of documentation.

I added a logo like you suggested and it miraculously worked. Bit ridiculous but at least it's sorted now!
Oh, Lord! This was a life saver. I was breaking my head with SHA 1 and google-services.json
Doesn't seem to fix it for me. Furthermore, once I add an Icon it seems that I need to verify this with google, wich can take up to 6 weeks. I have literally tried everything on Stackoverflow but nothing seems to work...

In my case, the problem was due to incompatible emulator. The emulator didn't had playstore.

I created a new AVD which has playstore in it. And then it worked!

Reference to create new emulator with Playstore

Also, verify that you have added the SHA1 key on firebase console.

Dude I searched evrything... and its just the Playstore....

I faced the same issue, I resolved it by adding the debug / release SHA1 and SHA256 certificate fingerprint using Keytool

Release

keytool -exportcert -list -v -alias <your-key-name> -keystore <path-to-production-keystore>

Debug

keytool -list -v -alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystore

More details here: https://developers.google.com/android/guides/client-auth

Change your emulator to another one that supports Google Play Store

Go to the API & Servcies page of your google account and make sure to select the project of your interest in the top left corner as shown below

enter image description here

Make sure you have the support email ID entered in the above

And all the below fields must have a value

I ran exatly into the same issue, what solved the issue for me was to add a SHA-256 fingerprint additionally to the SHA-1

as mentioned here -> Flutter and google_sign_in plugin: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null)

Hope that works for you too!

Just to add to this already huge list of ideas. After trying all of the things listed here I was still getting the error.

I had to add myself as a test user under the OAuth Consent Screen.

POSSIBLE CASE 2023

I had to face this problem too, during testing everything was working fine, but when I changed my project (actually build.gradle was the problem) to release mode the sign in process stopped to work as it was used to.

I tried to fill all the fields on Oauth consent screen (https://console.developers.google.com/apis/credentials), but nothing changed.

I also tried to check my SHA on Firebase, but both SHA-1 and SHA-256 were there.

As last resource I wanted to check my current SHA so in app/android folder I runned: ./gradlew signinReport and I found out that the SHA were changed.

So I uploaded them on Firebase and now everything is working fine.

In the end, check the SHA twice.

Check Application ID:-

Package Name on Google api console and Application Id in your app must be same, in my case it was different,

In my case, the Google Authentication provider was set with a support email and I was facing the same problem. So, I deleted the previous porvider and re-enabled a new Google Authentication provider and replaced old google-service.json file with newly downloaded file in <root>/android/app/ folder. This solved my problem.

In my case I had to set up two things:

  1. Go to Google Cloud console, select your app and in consent screen fill out the information required.

  2. I was using an emulator without Play Store. After I set up an emulator with Play Store installed, it worked.

In case it helps anyone: Try to run it on iOS, it might give you a better error description. In my case, I got the ApiException 12500 error on Android over and over again because I send an unknown scope:

  final _googleSignIn = GoogleSignIn(
    scopes: <String>[
      'name', // < "name" scope does not exist and causes ApiException 12500 on android
      'email',
    ],
  );

Running it on iOS gave me the exact error right away

Here is what works for me i have created sha1 from my production key store key.jks file enter this

keytool -list -v -alias <your-key-name> -keystore <path-to-production-keystore>

to your terminal give your keystore name <your-key-name> here and path of your keystore file or jks path here <path-to-production-keystore>.

this will genrate different SHA1 from your debug SHA1 put that SHA1 into firebase settings where is SHA certificate fingerprints

The other reason this issue may occur is if you have added scopes that are not approved in the OAuth screen.

Bear in mind that making certain changes to the OAuth screen will trigger Google's verification (this seems to include changes to the logo!)

Set up the following OAuth 2.0 Client IDs
* Web Application (Use this client id)
* Android Client with debug SHA1
* Android Client with keystore SHA1

In my case I had to also add another Android Client with the SHA1 of the app signing key from the Play store console

Of course update the google-service.json

final googleSignIn = GoogleSignIn(
    serverClientId: 'CLIENT-ID-FROM-WEB-APP',
    scopes: [
      'openid',
      'email',
      'profile',
    ],
