title: How can I implement this specific scroll animation using Flutter?
body: <p>I am trying to implement this scroll animation (GIF below). But, after extensive searching online, I haven't found any specific information to this problem. I looked at the <code>ScrollPhysics</code> class but I don't think that's the right path. My idea is to have transparent separators in between widgets and then to change the height of each separator to create the desired &quot;illusion&quot;. I would appreciate any suggestions on how to implement this thing.</p>
