title: Does the Dart programming language have an equivalent to Javascript's "prototype"?
body: <p>In Dart, is it possible for a function to have a prototype associated with it?</p>
  
  <p>Example Javascript code:</p>
  
  <pre><code>doStuff.prototype.isDefined = true; //is there anything like Javascript's function prototypes in Dart?
  function doStuff(){
      console.log("The function doStuff was called!");
  }
  </code></pre>
  
  <p>Is it possible to do the equivalent of this in Dart (i.e., create a list of properties for each function?)</p>
