                  final item = items[i];
                  return ItemSwiper(
                    item: item,
                    onTab: () => _.goToDetailItem(item: item),
                  );
                })

you can remove itemCount and try... But you cannot use a particular index, just showing a widget on that position. And you can print Index but make sure that you don't use an index with any external data source having limited data.

ListView.builder(
      itemBuilder: (BuildContext context, int index) {
        return ListTile(
          title: Text('Item ${index + 1}'),
        );
      },
    )
