title: Flutter: How to scroll a container rather than its content?
body: <p>Lets take a quick look at these two screenshots:</p>

  <ul>
  <li>The left screenshot shows a box (decorated container) containing a CustomScrollView that handles scrolling. This one's pretty easy to accomplish and works well.</li>
  <li>The right screenshot shows the intended behavior, where the box itself is scrolled, rather than its content. The problem is, that the box reaches out of the screens bounds, causing the overflow error message.
  Do you have any ideas how this could be accomplished anyway?<br />
  Thank you.</li>
