title: Flutter lower dart version
body: <p>I'm getting the following error due to Dart version of my flutter setup when I run the <code>flutter get packages</code> command:</p>
  
  <blockquote>
    <p>[project_name] flutter packages get   Running "flutter packages get"
    in project_name...<br>
    The current Dart SDK version is
    2.1.0-dev.0.0.flutter-be6309690f.</p>
    
    <p>Because project depends on intl_translation >=0.14.0+1 &lt;0.17.0 which
    requires SDK version >=1.12.0 &lt;2.0.0, version solving failed. pub get
    failed (1) exit code 1  </p>
  </blockquote>
  
  <p>My framework version:</p>
  
  <blockquote>
    <p>Flutter 0.6.0 • channel beta • <a href="https://github.com/flutter/flutter.git" rel="noreferrer">https://github.com/flutter/flutter.git</a><br>
    Framework • revision 9299c02cf7 (2 weeks ago) • 2018-08-16 00:35:12 +0200<br>
    Engine • revision e3687f70c7<br>
    Tools • Dart 2.1.0-dev.0.0.flutter-be6309690f</p>

  <p>I would like to learn if there's some kind of command to lower dart-sdk version of the flutter framework, thanks in advance.</p>
