itemBuilder property
finalinherited
Called, as needed, to build children widgets.
Children are only built when they're scrolled into view.
The AnimatedItemBuilder index parameter indicates the item's
position in the scroll view. The value of the index parameter will be
between 0 and initialItemCount
plus the total number of items that have
been inserted with AnimatedListState.insertItem
or
AnimatedGridState.insertItem
and less the total number of items that
have been removed with AnimatedListState.removeItem
or
AnimatedGridState.removeItem
.
Implementations of this callback should assume that
removeItem
removes an item immediately.
Implementation
