title: Calling native libraries in Flutter using Platform Channels
body: <p>Using <a href="https://flutter.io/platform-channels/" rel="noreferrer">platform channels</a>, Flutter can interop with the native platform (i.e. reading battery level). On Android, this would require calling a Java method.</p>
  
  <p>I'd like to use a third-party Java SDK (for AWS Cognito). Can I put this library somewhere in my <code>/android</code>, and interact with it? If so, how can I do that?</p>
