sameContent(T listA, int indexA, T listB, int indexB) → bool

IT compares the indexA of listA with the indexB of listB and returns true is they have the same content. This method is called after sameItem returned true, so this method tells if the same item has changed its content; if so a changing notification will be sent to the AnimatedListController.

sameItem(T listA, int indexA, T listB, int indexB) → bool

It compares the indexA of the listA with the indexB of the listB and returns true is they are the same item. Usually, the "id" of the item is compared here.
