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, @AtUriConverter()  AtUri uri,  String cid, @ProfileViewBasicConverter()  ProfileViewBasic author,  Map<String, dynamic> record, @UPostViewEmbedConverter()  UPostViewEmbed? embed,  int? bookmarkCount,  int? replyCount,  int? repostCount,  int? likeCount,  int? quoteCount,  DateTime indexedAt, @ViewerStateConverter()  ViewerState? viewer, @LabelConverter()  List<Label>? labels, @ThreadgateViewConverter()  ThreadgateView? threadgate,  Map<String, dynamic>? $unknown)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _PostView() when $default != null:
return $default(_that.$type,_that.uri,_that.cid,_that.author,_that.record,_that.embed,_that.bookmarkCount,_that.replyCount,_that.repostCount,_that.likeCount,_that.quoteCount,_that.indexedAt,_that.viewer,_that.labels,_that.threadgate,_that.$unknown);case _:
