  final MutationOptions _options = MutationOptions(
      document: gql(checkoutShippingLineUpdateMutation),
      variables: {
        'shippingRateHandle': shippingRateHandle,
        'checkoutId': checkoutId
      });
  final QueryResult result = await _graphQLClient!.mutate(_options);
  checkForError(
    result,
    key: 'checkoutShippingLineUpdate',

  if (deleteThisPartOfCache) {
    _graphQLClient!.cache.writeQuery(_options.asRequest, data: {});
