Social login using API in Laravel with Socialite to be consumed in an application in Flutter

Question

I am developing an API using Laravel 5.8 to be consumed in a flutter application. So, I’m using Laravel Socialite to log in with Facebook and Google. However, I’m still new to these frameworks and I don’t know how to log in to the application through the api with the socialite.

I used this code snippet for the site and it worked.

class SocialAuthController extends Controller
{
    public function redirect($social)
    {
        return Socialite::driver($social)->redirect();
    }

    public function callback($social)
    {
        $user = SocialAccountService::createOrGetUser(Socialite::driver($social)->stateless()->user(), $social);

        auth()->login($user);

        return redirect()->to('/');
    }
}

Can someone refer me some material or a solution to create an API using Socialite so that in the Flutter application I can consume this api and somehow receive the user data as a return of this api?
