title: Dart/SQFlite Import Error
body: <p>I am attempting to test out the SQFlite API by just creating a simple CLI. I can run the default sample app out of the same directory with both Android Studio and VS Code just fine and I can run other simple CLI programs just fine. Here is the contents of <code>lib/cli.dart</code>:</p>
  
  <pre><code>import 'package:sqflite/sqflite.dart';
  
  void main() {
    print('SQFlite Test');    
  }
  </code></pre>
  
  <p>When I run the code:</p>
  
  <pre><code>brianbuck$ dart --preview-dart-2 lib/cli.dart
  </code></pre>
  
  <p>I get the following error:</p>
  
  <pre><code>dart:ui: Error: Not found: dart:ui.
  </code></pre>
  
  <p>Here is the <code>pub.spec</code> file:</p>
  
  <pre><code>name: sqflite-test
  description: SQFlite Test
  
  dependencies:
    flutter:
      sdk: flutter
    cupertino_icons: ^0.1.0
    http: any
    sqflite: any
  </code></pre>
  
  <p>Is there a way to let the DartVM know that I have <code>dart:ui</code> installed?</p>
