title: Scroll multiple pages in PageView easier
body: <p>I am building a horizontally scrollable list in flutter using PageView, however, I would like to be able to scroll multiple pages at the same time. It is currently possible if I scroll really fast, but it is far from ideal. Another option is to set pageSnapping to false, but then it does not snap at all, which is not what I want.</p>
  
  <p>I am thinking that it might be possible to change pageSnapping from false to true if the scroll velocity is under a certain treshhold, but i don't know how I would get said velocity.</p>
  
  <p>The app i am building looks something <a href="https://cloud.netlifyusercontent.com/assets/344dbf88-fdf9-42bb-adb4-46f01eedd629/3f148997-00b3-4105-9922-66c5cf569f11/mobile-app-design-image108.gif" rel="nofollow noreferrer">like this</a>.</p>
  
  <p>All help appreciated!</p>
