@override Map<String, dynamic> toJson()

Converts the QueryModel to a JSON object.

@override
Map<String, dynamic> toJson() {
  final Map<String, dynamic> data = super.toJson();
  if (shipmentMethodPriceId != null) {
    data["shipmentMethodPriceId"] = shipmentMethodPriceId;
  }
  if (cashOnDelivery != null) data["cashOnDelivery"] = cashOnDelivery;
  return data;
}
