A Flutter plugin that makes it easy to perform OAuth sign in flows using FirebaseAuth. It also includes support for Sign in by Apple for Firebase. This plugin supports Android, iOS and Web. OAuth flows are performed by opening pop-up on top of the application to allow the user to authenticate or the native flow in the case of sign in by apple.

You need to set up Firebase for your project first before using this plugin. Instructions can be found here.

In your pubspec.yaml add

dependencies: flutter: sdk: flutter firebase_auth: ^0.18.0+1 firebase_core: ^0.5.0 firebase_auth_oauth: ^0.2.0

Then in your project just call

FirebaseUser user = await FirebaseAuthOAuth().openSignInFlow("A provider ID", [list of scopes], {custom parameters map}); // Sign-in by Apple example User user = await FirebaseAuthOAuth() .openSignInFlow("apple.com", ["email"], {"locale": "en"}); // Or you can link an existing logged-in user User user = await FirebaseAuthOAuth() .linkExistingUserWithCredentials("apple.com", ["email"], {"locale": "en"});
