title: How to put Doc comments for Dart function parameters?
body: <p>We can easily put Doc comments for Dart Class variables e.g.</p>
  
  <pre><code>class SomeClass {
  /// Class variable Doc Comment.
  var someVariable;
  
  }
  </code></pre>
  
  <p>How can I do the same for Dart Function parameters e.g. I tried this</p>
  
  <pre><code>void someFunction(
   {/// Function parameter documentation
   String funParameter="Some Default Value"}
  ) {
  
  }
  </code></pre>
  
  <p>But it's not showing anything. If it's not possible please suggest me any alternative.</p>
