title: Flutter::iOS Multiple Schemes Different Firebase Projects
body: <p>I am having multiple env scheme setup dev and prod and consequently I have two firebase projects for each env. I set up two schemes prod and dev on iOS and did follow instructions step by step as of the link <a href="https://www.tengio.com/blog/multiple-firebase-environments-with-flutter/" rel="nofollow noreferrer">https://www.tengio.com/blog/multiple-firebase-environments-with-flutter/</a> However when I try to sign in using google single signin I get this error <code>Unhandled Exception: PlatformException(google_sign_in, Your app is missing support for the following URL schemes</code> What I am missing?</p>
  
  <p>Error Log:</p>
