AnimatedGrid class

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

This widget's AnimatedGridState can be used to dynamically insert or remove items. To refer to the AnimatedGridState 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.
