when<TResult extends Object?> method

TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String $type,
    2. String did,
    3. String handle,
    4. String? displayName,

    13. VerificationState? verification,
    14. StatusView? status,
    15. 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,  String did,  String handle,  String? displayName,  String? pronouns,  String? description,  String? avatar, @ProfileAssociatedConverter()  ProfileAssociated? associated,  DateTime? indexedAt,  DateTime? createdAt, @ViewerStateConverter()  ViewerState? viewer, @LabelConverter()  List<Label>? labels, @VerificationStateConverter()  VerificationState? verification, @StatusViewConverter()  StatusView? status,  Map<String, dynamic>? $unknown)  $default,) {final _that = this;
switch (_that) {
case _ProfileView():
return $default(_that.$type,_that.did,_that.handle,_that.displayName,_that.pronouns,_that.description,_that.avatar,_that.associated,_that.indexedAt,_that.createdAt,_that.viewer,_that.labels,_that.verification,_that.status,_that.$unknown);case _:
