title: Creating a new Flutter plugin: io.flutter.plugin.common module not resolved
body: <p>I am willing to create a Flutter plugin (to work with native code), but after opening the android native module of the Flutter project using Android Studio all the import statements for Flutter native components <a href="https://drive.google.com/open?id=1iRsoqCx2czLNjHssoFgA8-rAMbHTI-41" rel="nofollow noreferrer">are highlighted as red</a>, starting from top-level package identifier - <code>io</code>, which means that the whole module is not resolved.
  Still, it is possible to launch the example project inside and it runs OK.</p>
  
  <p><a href="https://drive.google.com/open?id=1jig4ewxDOQtIutBKPv3tJc7p_fBWaxMo" rel="nofollow noreferrer">Such a problem does not occur for application-typed Flutter projects</a> (worth mentioning that imports are not the same, but still, all the necessary imports are resolved).</p>
  
  <p>Am I missing something, or it is Flutter-side bug for now? If latter, than is there a workaround for it (e.g. manually providing a library, but where is it located)?</p>
