whenOrNull<TResult extends Object?> method
- @optionalTypeArgs
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 $type, @AtUriConverter() AtUri uri, String cid, @ProfileViewConverter() ProfileView creator, int? likeCount, @LabelerViewerStateConverter() LabelerViewerState? viewer, DateTime indexedAt, @LabelConverter() List<Label>? labels, Map<String, dynamic>? $unknown)? $default,) {final _that = this;
switch (_that) {
case _LabelerView() when $default != null:
return $default(_that.$type,_that.uri,_that.cid,_that.creator,_that.likeCount,_that.viewer,_that.indexedAt,_that.labels,_that.$unknown);case _:
return null;
}
