    )
)

A switch-like method, using callbacks.

As opposed to map, this offers destructuring. It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case Subclass2(:final field2):
    return ...;
}

Implementation

@optionalTypeArgs TResult when<TResult extends Object?>(TResult Function( String $type,  int id,  String name, @QueueViewSubjectTypesConverter()  List<QueueViewSubjectTypes>? subjectTypes,  String? collection,  List<String>? reportTypes,  String? description,  String createdBy, @JsonKey(toJson: iso8601)  DateTime createdAt, @JsonKey(toJson: iso8601)  DateTime updatedAt,  bool enabled, @JsonKey(toJson: iso8601)  DateTime? deletedAt, @QueueStatsConverter()  QueueStats stats,  Map<String, dynamic>? $unknown)  $default,) {final _that = this;
switch (_that) {
case _QueueView():
return $default(_that.$type,_that.id,_that.name,_that.subjectTypes,_that.collection,_that.reportTypes,_that.description,_that.createdBy,_that.createdAt,_that.updatedAt,_that.enabled,_that.deletedAt,_that.stats,_that.$unknown);case _:
  throw StateError('Unexpected subclass');
