title: Firebase Auth uses or overrides a deprecated API
body: <p>I'm trying to start my flutter application using <code>flutter run</code> but am getting an error when I do.</p>
  
  <p>The following error shows: </p>
  
  <p><code>Note: C:\flutter\.pub-cache\hosted\pub.dartlang.org\firebase_auth-0.5.10\android\src\main\java\io\flutter\plugins\firebaseauth\FirebaseAuthPlugin.java uses or overrides a deprecated API.</code></p>
  
  <p><code>Note: Recompile with -Xlint:deprecation for details.</code></p>
  
  <p>I've looked up some fixes, mostly people saying that the versions are outdated, not the case (<code>Flutter version: 0.4.4 beta</code>, <code>Firebase version: 0.5.10</code>).</p>
  
  <p>Does anyone know why this may be happening?</p>
