title: How to build and maven-publish a flutter aar?
body: <p>I am working on a flutter project and I am building aar out of it. This aar I am able to integrate into my native android project by following the instructions provided by the flutter.
  But my problem is that this aar is integrated locally. I want to maven-publish this aar so that it can be accessed easily by team members. </p>
  
  <p>Publishing out from the native library is possible with the help of the <code>publishing</code> task in grade. But for the flutter library, I am not sure what we are supposed to do. So, I need help with this.</p>
