Hi @WaseemAbbasi22, Thanks for filing the issue. I see the issue in your code, you are not passing item parameters to SearchFieldListItem

return filter
              .map((e) => SearchFieldListItem<String>(
                  item: e,  // Pass the object you want to receive for the list item
                  searchLabel != null ? e.fullName : e.name!,
                  child: Padding(
                    padding: const EdgeInsets.symmetric(
                        vertical: 4.0, horizontal: 5.0),
                    child: Text(searchLabel != null ? e.fullName : e.name!,
                        style: AppStyle.lightDarkTextStyle.copyWith(
                            fontSize: 1.8.h, fontWeight: FontWeight.normal)),
                  )))
              .toList();

See this complete example for more details https://github.com/maheshmnj/searchfield/blob/master/example/lib/country_search.dart

Additionally I have updated the doc comments a little bit to clarify this.
