What do you suggest ?

Hey @salim-lachdhaf There is probably a nice pattern to follow, check the gif on main page of https://pub.dev/packages/infinite_scroll_pagination

When there is an error during fetching the data the list is being replaced by the error message widget. There is also a retry callback being passed to error widget so user could build the error widget with refresh button.

You can spot one of those examples on gif (at the very bottom)

In addition to error refresh - the pull to refresh mechanism for the list view would be a nice addition

I want a way to trigger items function again in errorBuilder

This is my temporary solution: errorBuilder: (context, searchEntry, exception) {

          return Column(
            mainAxisAlignment: MainAxisAlignment.center,
            crossAxisAlignment: CrossAxisAlignment.stretch,
            children: [
              Text(
                textAlign: TextAlign.center,
                LocKeys.someErrorOccur.tr(context: context),
                style: TextStyle(color: appColors.webTextColor),
              ),
              if (widget.onRefreshError != null)
                Padding(
                  padding: const EdgeInsets.all(8.0),
                  child: CommonButtonWidget(
                    callBack: () async {
                      _searchController.text = '###';
                      widget.onRefreshError!().whenComplete(
                        () => _searchController.text = originalText,
                      );
                    },
                    label: LocKeys.refresh.tr(context: context),
                    icon: const Icon(
                      Icons.refresh,
                    ),
                  ),
                ),
            ],
          );
        }
