title: Is there any dart library for the Google Authenticator?
body: <p>I'm looking for a way to implement/connect the Google-Authenticator into Flutter/Dart. The goal is to be able to validate codes generated in the Google-Authenticator app to create a two-step authentication.</p>
  
  <p>Maybe I'm blind, but due to the name, it's really hard to find anything on it (thanks to the word "authenticator"). The best I could find so far was a PHP port: <a href="https://packagist.org/packages/sonata-project/google-authenticator" rel="nofollow noreferrer">https://packagist.org/packages/sonata-project/google-authenticator</a></p>
  
  <p>I'm having trouble to even just find an API Documentation on the Authenticator.</p>
  
  <p>Before I start to write my own implementation: Is there any implementation for Dart already? Where can I find the Google-Authenticator documentation?</p>
  
  <p>Edit 1: clarified the part about implementing Google-Authenticator (to verify codes).</p>
