whenOrNull<TResult extends Object?> method

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? $default(String id, String? name, String userId, String credentialID, String publicKey, @JsonKey.new(fromJson: _counterFromJson) int counter, String deviceType, bool backedUp, String? transports, DateTime? createdAt, DateTime? updatedAt, String? aaguid,)?)

A variant of when that fallback to returning null

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return null;
}

Implementation

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? Function( String id,  String? name,  String userId,  String credentialID,  String publicKey, @JsonKey(fromJson: _counterFromJson)  int counter,  String deviceType,  bool backedUp,  String? transports,  DateTime? createdAt,  DateTime? updatedAt,  String? aaguid)?  $default,) {final _that = this;
switch (_that) {
case _PasskeyRecord() when $default != null:
return $default(_that.id,_that.name,_that.userId,_that.credentialID,_that.publicKey,_that.counter,_that.deviceType,_that.backedUp,_that.transports,_that.createdAt,_that.updatedAt,_that.aaguid);case _:
  return null;

}
