itemBuilder property

Widget Function(BuildContext context, int itemIndex, int realIndex) itemBuilder
final

To lazily build items on the viewport.

When Loop: false, ItemIndex is equal to RealIndex (i.e, index of element).

When loop: true, two indexes are exposed by item builder.

One is itemIndex, that is the modded item index i.e., for list of 10, position(11) = 1, and position(-1) = 9.

Other is realIndex, that is the actual index, i.e. ..., -2, -1, 0, 1, 2, ... in loop. Real Index is needed if you want to support JumpToItem by tapping on it.

Implementation

final Widget Function(BuildContext context, int itemIndex, int realIndex)
    itemBuilder;
