title: dart CLI command -why no lib/proj.dart file? dart ctreate <project_name>
body: <p>whenever I used dart CLI command</p>
  <pre><code>dart create &lt;project_name&gt;
  </code></pre>
  <p>i used to get a nice project folder with a lib/project.dart file inside the file there would be a some nice peace of code like this:</p>
  <pre><code>int calculate() {
    return 6 * 8;
  }
  
  </code></pre>
  <p>which you would import in the main file. a nice touch overall. but there is no lib folder or file, why??</p>
  <p>i am using linux OS, dart version 2.3:</p>
  <p>Dart SDK version: 2.13.4 (stable) (Unknown timestamp) on &quot;linux_x64&quot;</p>
