when<TResult extends Object?> method

@optionalTypeArgs TResult when<TResult extends Object?>(TResult $default(String $type, @RecordHostingStatusConverter() RecordHostingStatus status, @JsonKey.new(toJson: iso8601) DateTime? updatedAt, @JsonKey.new(toJson: iso8601) DateTime? createdAt, @JsonKey.new(toJson: iso8601) DateTime? deletedAt, Map<String, dynamic>? $unknown,))

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, @RecordHostingStatusConverter()  RecordHostingStatus status, @JsonKey(toJson: iso8601)  DateTime? updatedAt, @JsonKey(toJson: iso8601)  DateTime? createdAt, @JsonKey(toJson: iso8601)  DateTime? deletedAt,  Map<String, dynamic>? $unknown)  $default,) {final _that = this;
switch (_that) {
case _RecordHosting():
return $default(_that.$type,_that.status,_that.updatedAt,_that.createdAt,_that.deletedAt,_that.$unknown);case _:
  throw StateError('Unexpected subclass');

}
