title: How to implement cycle wheel scroll list widget
body: <p>Flutter has ListWheelScrollView widget but I want <em>cycle</em> wheel scroll widget. Any ideas how to implement such widget.</p>
  
  <p>How it should work:</p>
  
  <p>For example, I have a list with 10 items and a selected item is 1
  The selected element is positioned by center
  above this element, you see the last element in the list below the second element</p>
  
  <pre><code>   [10]
  -&gt; [1] &lt;-
     [2]
  </code></pre>
  
  <p>scroll down</p>
  
  <pre><code>   [9]
  -&gt; [10] &lt;-
     [1]
  </code></pre>
  
  <p>etc.</p>
  
  <p>Thanks!</p>
