query method Null safety

Future<PostgreSQLResult> query(
  1. String fmtString,
  2. {Map<String, dynamic>? substitutionValues,
  3. bool? allowReuse,
  4. int? timeoutInSeconds}
)

Implementation

Future<PostgreSQLResult> query(String fmtString,
    {Map<String, dynamic>? substitutionValues,
    bool? allowReuse,
    int? timeoutInSeconds});
