when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String $type,
    2. @AtUriConverter.new() AtUri uri,
    3. String cid,
    4. Map<String, dynamic> record,
    5. @ProfileViewBasicConverter() ProfileViewBasic creator,
    6. int? listItemCount,
    7. int? joinedWeekCount,
    8. int? joinedAllTimeCount,
    9. @LabelConverter() List<Label>? labels,
    10. DateTime indexedAt,
    11. Map<String, dynamic>? $unknown,
    )
)

A switch-like method, using callbacks.

As opposed to map, this offers destructuring. It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case Subclass2(:final field2):
    return ...;
}

Implementation

@optionalTypeArgs TResult when<TResult extends Object?>(TResult Function( String $type, @AtUriConverter()  AtUri uri,  String cid,  Map<String, dynamic> record, @ProfileViewBasicConverter()  ProfileViewBasic creator,  int? listItemCount,  int? joinedWeekCount,  int? joinedAllTimeCount, @LabelConverter()  List<Label>? labels,  DateTime indexedAt,  Map<String, dynamic>? $unknown)  $default,) {final _that = this;
switch (_that) {
case _StarterPackViewBasic():
return $default(_that.$type,_that.uri,_that.cid,_that.record,_that.creator,_that.listItemCount,_that.joinedWeekCount,_that.joinedAllTimeCount,_that.labels,_that.indexedAt,_that.$unknown);case _:
  throw StateError('Unexpected subclass');
