Remember add key to the page widget that created by DismissibleCarouselViewPager.itemBuilder.

I recommend using the data that preparing to create page widget to create Key("$data"), ValueKey(data) or ObjectKey(data) for the page widget.

late final List<int> _item = List.generate(1000, (index) => index);

DismissibleCarouselViewPager(
  itemCount: _item.length,
  itemBuilder: (context, index) {
    Object data = _item[index];
    return Container(
      // must add key
      key: Key("$data"),
      //key: ValueKey(data),
      //key: ObjectKey(data),
      alignment: Alignment.center,
      color: Colors.grey.withOpacity(0.1),
      child: Column(
        mainAxisSize: MainAxisSize.min,
        children: [
        Expanded(
          child: Container(
            alignment: Alignment.bottomCenter,
            child: Text("Item:$data"),
          ),
        ),
        Expanded(
          child: IconButton(
            icon: const Icon(Icons.delete),
            onPressed: () {
                setState(() {
                  _item.remove(data);
                });
              },
            ),
          ),
        ],
      ),
    );
  },
  dismissalConfig: DismissalConfig(
    dismissalTypes: [
      DismissalType.fadeOut(),
      DismissalType.slideOut(),
    ],
  ),
);
