AnimatedList class

A scrolling container that animates items when they are inserted or removed.

This widget's AnimatedListState can be used to dynamically insert or remove items. To refer to the AnimatedListState either provide a GlobalKey or use the static of method from an item's input callback.

This widget is similar to one created by ListView.builder.
