    public function getUrlLogin()
    {
        return $this->helper->getLoginUrl(Config::get('facebook.app_scope'));
    }

Answer 1

You do return in your constructor before you set the value of $this->helper, that's why you are getting the error.

Replace

public function __construct() {
  return FacebookSession::setDefaultApplication(Config::get('facebook.app_id'), Config::get('facebook.app_secret'));
  $this->$helper = new FacebookRedirectLoginHelper(url('login/fb/callback'));
}

with

public function __construct() {
  FacebookSession::setDefaultApplication(Config::get('facebook.app_id'), Config::get('facebook.app_secret'));
  $this->$helper = new FacebookRedirectLoginHelper(url('login/fb/callback'));
}
