title: VSCode: search classes / go to class for imported libraries
body: <p>What is the VSCode equivalent to IntelliJ's <strong>Go to class</strong> ? I.e. I want to type in the class name and receive a pop-up list of all the classes that match my pattern. However, these should include not-only my project's classes but also <strong>imported libraries' classes</strong>.</p>
  
  <p>InteliJ has an option "Include non-project items" when you look for classes using <code>⌘ + O</code> or <code>ctrl+O</code>.  </p>
  
  <p>The language I'm using is: Dart.</p>
