A way to get the list of value Strings instead of the integer indexes is to map into a new variable like this:

List<String> selectedItemsInString=value.map<String>((index)=>items[index].value.toString()).toList();

Here is below the "Multi dialog" example with this new variable printed:

SearchChoices.multiple(
        items: items,
        selectedItems: selectedItemsMultiDialog,
        hint: Padding(
          padding: const EdgeInsets.all(12.0),
          child: Text("Select any"),
        ),
        searchHint: "Select any",
        onChanged: (value) {

          List<String> selectedItemsInString=value.map<String>((index)=>items[index].value.toString()).toList();
          selectedItemsInString.forEach((element) {
            print("selected: $element");
          });

          setState(() {
            selectedItemsMultiDialog = value;
          });
        },
        closeButton: (selectedItems) {
          return (selectedItems.isNotEmpty
              ? "Save ${selectedItems.length == 1 ? '"' + items[selectedItems.first].value.toString() + '"' : '(' + selectedItems.length.toString() + ')'}"
              : "Save without selection");
        },
        isExpanded: true,
      )
