Can I customize the "Error - retry" button?

Hello @rhernandez-itemsoft ,

Thanks for your request. At the moment, there is no easy way to customize the “Error - retry” button and this is missing. I will mark this issue as an enhancement and work on it as soon as I can.

Hello @rhernandez-itemsoft ,

The latest release 1.0.15 available on pub.dev should address your request with the following example:
https://github.com/lcuis/search_choices#Single-dialog-future-custom-error-button

SearchChoices.single(
        value: selectedValueSingleDialogFuture,
        hint: kIsWeb ? "Example not for web" : "Select one capital",
        searchHint: "Search capitals",
        onChanged: kIsWeb
            ? null
            : (value) {
          setState(() {
            selectedValueSingleDialogFuture = value;
          });
        },
        isExpanded: true,
        selectedValueWidgetFn: (item) {
          return (Center(
              child: Card(
                  shape: RoundedRectangleBorder(
                    borderRadius: BorderRadius.circular(4),
                    side: BorderSide(
                      color: Colors.grey,
                      width: 1,
                    ),
                  ),
                  margin: EdgeInsets.all(1),
                  child: Padding(
                    padding: const EdgeInsets.all(6),
                    child: Text(item["capital"]),
                  ))));
        },
        futureSearchFn: (String? keyword, String? orderBy, bool? orderAsc,
            List<Tuple2<String, String>>? filters, int? pageNb) async {
          String filtersString = "";
          int i = 1;
          filters?.forEach((element) {
            // This example doesn't have any futureSearchFilterOptions parameter, thus, this loop will never run anything.
            filtersString += "&filter" +
                i.toString() +
                "=" +
                element.item1 +
                "," +
                element.item2;
            i++;
          });
          Response response = await get(Uri.parse(
              "https://FAULTYsearchchoices.jod.li/exampleList.php?page=${pageNb ?? 1},10${orderBy == null ? "" : "&order=" + orderBy + "," + (orderAsc ?? true ? "asc" : "desc")}${(keyword == null || keyword.isEmpty) ? "" : "&filter=capital,cs," + keyword}$filtersString"))
              .timeout(Duration(
            seconds: 10,
          ));
          if (response.statusCode != 200) {
            throw Exception("failed to get data from internet");
          }
          dynamic data = jsonDecode(response.body);
          int nbResults = data["results"];
          List<DropdownMenuItem> results = (data["records"] as List<dynamic>)
              .map<DropdownMenuItem>((item) => DropdownMenuItem(
            value: item,
            child: Card(
              shape: RoundedRectangleBorder(
                borderRadius: BorderRadius.circular(4),
                side: BorderSide(
                  color: Colors.blue,
                  width: 1,
                ),
              ),
              margin: EdgeInsets.all(10),
              child: Padding(
                padding: const EdgeInsets.all(6),
                child: Text(
                    "${item["capital"]} - ${item["country"]} - ${item["continent"]} - pop.: ${item["population"]}"),
              ),
            ),
          ))
              .toList();
          return (Tuple2<List<DropdownMenuItem>, int>(results, nbResults));
        },
        futureSearchRetryButton: (Function onPressed) => Column(children: [
          SizedBox(height: 15),
          Center(
            child: ElevatedButton.icon(
                onPressed: (){onPressed();},
                icon: Icon(Icons.repeat),
                label: Text("Intentional error - retry")),
          )
        ]),
      )

I hope this will work for you.
