title: How do you print a dollar sign $ in Dart
body: <p>I need to actually print a Dollar sign in Dart, ahead of a variable.  For example:</p>
  
  <pre class="lang-dart prettyprint-override"><code>void main()
  {
    int dollars=42;
    print("I have $dollars."); // I have 42.
  }
  </code></pre>
  
  <p>I want the output to be:  I have $42.  How can I do this?  Thanks.</p>
