where method Null safety

Query where(
  1. String field,
  2. {String? isEqualTo,
  3. int? isGreaterThan,
  4. int? isGreaterThanOrEqualTo,
  5. int? isLessThan,
  6. int? isLessThanOrEqualTo,
  7. String? contains}
)

Implementation

Query where(
  String field, {
  String? isEqualTo,
  int? isGreaterThan,
  int? isGreaterThanOrEqualTo,
  int? isLessThan,
  int? isLessThanOrEqualTo,
  String? contains,
}) =>
    Query(client, index, compoundBody, field,
        isEqualTo: isEqualTo,
        isGreaterThan: isGreaterThan,
        isGreaterThanOrEqualTo: isGreaterThanOrEqualTo,
        isLessThan: isLessThan,
        isLessThanOrEqualTo: isLessThanOrEqualTo,
        contains: contains);
