title: Flutter Packages Get Failed
body: <p>I am trying to add this library to my flutter project: <a href="https://pub.dartlang.org/packages/charts_flutter#-installing-tab-" rel="nofollow noreferrer">https://pub.dartlang.org/packages/charts_flutter#-installing-tab-</a></p>
  
  <p>When I add the dependency to my pubspec.yaml file and hit packages get, I get the following error:</p>
  
  <blockquote>
    <p>The current Dart SDK version is 2.1.0-dev.9.4.flutter-f9ebf21297.</p>
    
    <p>Because charts_flutter >=0.6.0 depends on charts_common >=0.6.0 which
    requires SDK version >=2.1.0 &lt;3.0.0, charts_flutter >=0.6.0 is
    forbidden. So, because undaunted_golf_flutter depends on
    charts_flutter ^0.6.0, version solving failed.</p>
    
    <p>pub get failed (1) Process finished with exit code 1</p>
  </blockquote>
  
  <p>To me, it looks like I have the most up to date version of Dart, which matches the minimum version the chart_common library requires. I updated my Android Studio yesterday (2/15/2019), the same day the charts_flutter and charts_common were updated.</p>
  
  <p>What am I missing here?</p>
