mutate<T> method

Future<T> mutate<T>(String mutation, Map<String, dynamic> variables, { T fromJson(Map<String, dynamic>)?, String? expectedDataType, bool convertEnums = true, bool retryOnTransientNetworkErrors = true, })

Implementation

    convertEnums: convertEnums,
    retryOnTransientNetworkErrors: retryOnTransientNetworkErrors,
  );

  }

  if (data is Map || data is List) {
    // Response normalization: always convertEnums=false because entity
    // .g.dart files now use @JsonValue enum maps (_$EnumNameEnumMap) which
    // expect the raw GraphQL enum values (e.g. 'USD', 'INSUFFICIENT_STOCK_ERROR').
    // The __typename -> runtimeType conversion still runs for union discrimination.
    data = VendureUtils.normalizeGraphQLData(
      data,
