Is there a way to create a User with Google Signin? about laravel-firebase HOT 2 CLOSED

In theory it should work like this:

$result = $auth->linkProviderThroughAccessToken('twitter', $twitterAccessTokenString)`;
$userRecord = $result->userRecord;

$result = $auth->linkProviderThroughAccessToken('google', $googleAccessTokenString)`;
$userRecord = $result->userRecord;

When sent to the Firebase API, the access token will be parsed by them - if a matching user already exists (I don't know for sure how users would be matched), the credentials will be linked to the existing user. If no matching user exists, a new one will be created. Either way, you should receive a user record and consider the user signed in.

The method is poorly named and undocumented because I added it in a weak moment when someone needed it, but I'm not able to reliably test it, and it's a functionality that would better be implemented in the frontend of an application.

The flow that I would suggest in a web application would be to let the user sign in to Firebase in the browser (e.g. with https://firebase.google.com/docs/auth/web/firebaseui). There, you can get an ID token for the currently signed-in user as described in https://firebase.google.com/docs/auth/admin/verify-id-tokens#retrieve_id_tokens_on_clients

This ID token can then be sent to your Laravel App and be verified by the SDK with

$auth = app('firebase.auth');
$token = $auth->verifyIdToken($receivedIdTokenString);
$userRecord = $auth->getUser($token->getClaim('sub'));

Great, thanks so much.
