addDeliveryAddresses method

Future<Cart> addDeliveryAddresses({ required String cartId, required List<CartSelectableAddressInput> addresses, bool reverse = false, })

Adds delivery addresses to an existing cart.

Replaces passing deliveryAddressPreferences through updateBuyerIdentityInCart, which Shopify deprecated. The added addresses are available on Cart.delivery.

If the reverse is set to true, the line items in the cart will be in reverse order.

Implementation

Future<Cart> addDeliveryAddresses({
  required String cartId,
  required List<CartSelectableAddressInput> addresses,
  bool reverse = false,
}) async {
  final MutationOptions addAddresses = MutationOptions(
    document: gql(cartDeliveryAddressesAddMutation),
    variables: {
      'cartId': cartId,
      'addresses': addresses.map((e) => e.toJson()).toList(),
      'reverse': reverse,
      'country': ShopifyLocalization.countryCode,
    },
  );
  QueryResult result = await _graphQLClient!.mutate(addAddresses);
  checkForError(result,
      key: 'cartDeliveryAddressesAdd', errorKey: 'userErrors');

  return Cart.fromJson(
      ((result.data!['cartDeliveryAddressesAdd'] ?? const {})['cart'] ??
          const {}));
}
