## Implementation

    String? image(KeyValue k) {

        if (images == null) return null;
        var index = images!.indexWhere((element) => element.reference == k.value);
        var documentItemModel = images![index];
        var image = documentItemModel.image;
        if (index >= 0) return image!.url;
      } catch (_) {

      }
      return null;
