A list view with basic must-to-have UX.

1. Show loading

2. Drag to refresh

3. Next page on scroll to bottom

A list view in flutter has some common basic required UX as described in Features. The problem is, most designers (according to my experiences) is only showing the design with defined data to the design. Ignoring the states or basic UX that should be available in every list view. And programmers might miss some of those required minimum common UX list view.
