title: How to implement Horizontal Icon list menu using flutter
body: <p>Basically I want to implement something like below ,</p>
  
  <ul>
  <li>There is a menu button in the right up corner of the mobile.
  If user clicks that, horizontal bar <strong>(like a google search bar in the android mobile)</strong> opens in the left which contains the list of scrollable icons horizontally.</li>
  </ul>
  
  <p>Is there any existing widget already present in Flutter ?
  Kindly let me know how to develop this feature</p>
