     return $data == "google"; // returning true/false
  }

  public function isLoginWithFacebook($data){
     return $data == "facebook"; // returning true/false
  }

Important Note: $provider is a dynamic parameter which is receiving "facebook","google", "twitter","LinkedIn" etc from the URL.

Note: Always keep your eyes on official documentation.
