              onPressed: () {

            AppListItem(onClick: listClick, index: 7),
          ],
        ),
      ),
    );
  }

  // Improvement/Suggestion 4.4 -> Running AddTOCartAnimation BEFORE runCArtAnimation
  void listClick(GlobalKey gkImageContainer) async {
    await runAddToCardAnimation(gkImageContainer);
    await gkCart.currentState!.runCartAnimation((++_cartQuantityItems).toString());
  }
}

By the way, you can run the example project in the plugin to check it deeply.

Have a good days.
