title: Flutter users should run `flutter packages get` instead of `pub get`
body: <p>I got a flutter project to complete from my friend.</p>
  
  <p>I am using Android Studio(AS) as editor. I have installed flutter and dart plugins in AS. Now, I have imported the flutter project by selecting option at start of AS import AS project. Then it I don't know why it shown me error message to setup Dart SDK(Q1: my first question is why it is giving error I already have dart plugin). Somehow I managed to get Dart from <a href="http://www.gekorm.com/dart-windows/" rel="nofollow noreferrer">this link</a> and gave path to till dart-sdk folder as seen in screenshot

  And now I am stuck on this error:</p>
  
  <pre><code>Because xxo_tag_xxxls depends on flutter_test any from sdk which doesn't exist (the Flutter SDK is not available), version solving failed.
  </code></pre>
  
  <p>Flutter users should run <code>flutter packages get</code> instead of <code>pub get</code>.</p>
