removedSeparatorBuilder property
finalinherited
Called, as needed, to build separator widgets.
Separators are only built when they're scrolled into view.
The AnimatedItemBuilder index parameter indicates the
separator's corresponding 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
and less the total number of items that have been removed with AnimatedListState.removeItem
.
Implementations of this callback should assume that
removeItem
removes an item immediately.
Implementation
final AnimatedItemBuilder? removedSeparatorBuilder;
