title: How to build Flutter project with Android aar file?
body: <p>I want to use <strong>Flutter</strong> to create an Android app which depends on a third-party SDK that wrapped in an <strong>aar</strong> file. So far, I have only found the article <a href="https://flutter.io/platform-services/" rel="noreferrer">Accessing Platform and Third-Party Services in Flutter</a>. It seems that I have to build the Flutter project with additional Java files using <strong>Android Studio</strong>. This is complicated and not what I want. 
  Is there any way to directly load aar files or *.so files in <strong>Dart</strong> code? Something like how <strong>JNI</strong> works.</p>
