title: How to create an empty list in Dart
body: <p>I want to create an empty list for a Flutter project.</p>
  
  <pre><code>final prefs = await SharedPreferences.getInstance();
  final myStringList = prefs.getStringList('my_string_list_key') ?? &lt;empty list&gt;;
  </code></pre>
  
  <p>I seem to remember there are multiple ways but one recommended way. How do I do it?</p>
