title: Cannot resolve symbol FlutterActivity
body: <p>I imported flutter project from github into Android Studio with 'VCS -> Checkout from Version Control'. And now I'm facing the issue: <code>Cannot resolve symbol FlutterActivity</code> in android's MainActivity.java. </p>
  
  <p>I created another flutter project with <code>New Flutter Project</code> wizard. And there was no that kind of issue. The difference between the two projects was that the project from github didn't have <code>External Libraries/Flutter for Android/flutter.jar</code> whereas created from scratch one had. </p>
  
  <p>I compared pubspec.yaml and build.gradle files of both projects and didn't find anything that looks like related to that dependency.</p>
  
  <p>Here the pubspec.yaml of the project in question:</p>
  
  <pre><code>name: utopian_rocks_mobile
  description: A new Flutter project.
  
  version: 1.0.0+1
  
  environment:
    sdk: "&gt;=2.0.0-dev.68.0 &lt;3.0.0"
  
  dependencies:
    flutter:
      sdk: flutter
  
    http: ^0.12.0
    rxdart: ^0.19.0
    cupertino_icons: ^0.1.2
  
  dev_dependencies:
    flutter_test:
      sdk: flutter
  
  
  flutter:
  
    uses-material-design: true
  </code></pre>
  
  <p>How that kind of dependency supposed to be handled in a flutter project?</p>
