whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String $type,
    2. AtUri uri,
    3. String cid,
    4. Map<String, dynamic> record,
    5. ProfileViewBasic creator,
    6. ListViewBasic? list,
    7. List<ListItemView>? listItemsSample,
    8. List<GeneratorView>? feeds,
    9. int? joinedWeekCount,
    10. int? joinedAllTimeCount,
    11. List<Label>? labels,
    12. DateTime indexedAt,
    13. Map<String, dynamic>? $unknown,
    )?
)

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,  Map<String, dynamic> record, @ProfileViewBasicConverter()  ProfileViewBasic creator, @ListViewBasicConverter()  ListViewBasic? list, @ListItemViewConverter()  List<ListItemView>? listItemsSample, @GeneratorViewConverter()  List<GeneratorView>? feeds,  int? joinedWeekCount,  int? joinedAllTimeCount, @LabelConverter()  List<Label>? labels,  DateTime indexedAt,  Map<String, dynamic>? $unknown)?  $default,) {final _that = this;
switch (_that) {
case _StarterPackView() when $default != null:
return $default(_that.$type,_that.uri,_that.cid,_that.record,_that.creator,_that.list,_that.listItemsSample,_that.feeds,_that.joinedWeekCount,_that.joinedAllTimeCount,_that.labels,_that.indexedAt,_that.$unknown);case _:
  return null;
