 <category android:name="android.intent.category.DEFAULT" />
 <category android:name="android.intent.category.BROWSABLE" />

Add to your info.plist

<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleTypeRole</key>
<string>Editor</string>

<string>[your firebase project name].firebaseapp.com</string>
<key>CFBundleURLSchemes</key>
<array>
<string>https</string>
</array>
</dict>
</array>

First instanciate FirebaseAuthFacade and inject GoogleSignIn and FirebaseAuth. Then you have to call the method call() on the instance => authFacade() callbackUrl is required, you can find it in your firebase panel in the github sign in method or apple sign in method.

You can use injectable like this and inject it into your Bloc:

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

@module
abstract class PackagesInjectableModule {
  @lazySingleton
  IAuthFacade get authFacade {
    final _firebaseAuth = FirebaseAuth.instance;
    final _googleSignIn = GoogleSignIn();
    final authFacade = FirebaseAuthFacade(_firebaseAuth, _googleSignIn);
    authFacade(
      callbackUrl:
          environment == Environment.dev ? callbackUrlDev : callbackUrl,
      githubClientId:
          environment == Environment.dev ? githubClientIdDev : githubClientId,
      githubSecret:
          environment == Environment.dev ? githubSecretDev : githubSecret,
    );
    return authFacade;
  }
}

Real life example

  • You can find a real life app open source being build here: flutterence

Simple example

The sign in methods are returning a Future<Either<AuthFailure, unit>>, so you'll have to use Dartz and fold the result like this:

final failureOrSuccess = _authFacade.signInWithGitHub();
failureOrSuccess.fold(
    (failure) => print(failure), // Handle the failure here
    (success) => print("User logged in")// handle the user here
);

Handle error

The AuthFailure class use Freezed with code generation so you can use Unions/sealed class feature:

    failure.map(

            );
    failure.maybeMap();
    failure.when();
    //etc...
