A variant of when that fallback to an orElse callback.

It is equivalent to doing:

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

Implementation

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult Function( String $type,  String uri,  String title,  String description, @JsonKey(toJson: iso8601)  DateTime? createdAt, @JsonKey(toJson: iso8601)  DateTime? updatedAt, @LabelConverter()  List<Label>? labels, @RepoStrongRefConverter()  List<RepoStrongRef>? associatedRefs, @ProfileViewBasicConverter()  List<ProfileViewBasic>? associatedProfiles,  String? image,  bool active, @JsonKey(toJson: iso8601)  DateTime? startedAt, @JsonKey(toJson: iso8601)  DateTime? endedAt,  Map<String, dynamic>? $unknown)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _EmbedExternalViewLivestream() when $default != null:
