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, @BskyAppProgressGuideConverter() BskyAppProgressGuide? activeProgressGuide, List<String>? queuedNudges, @NuxConverter() List<Nux>? nuxs, Map<String, dynamic>? $unknown)? $default,) {final _that = this;
switch (_that) {
case _BskyAppStatePref() when $default != null:
return $default(_that.$type,_that.activeProgressGuide,_that.queuedNudges,_that.nuxs,_that.$unknown);case _:
return null;
}
}
