maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String $type,
    2. String did,
    3. String handle,
    4. String? displayName,
    5. String? pronouns,
    6. String? avatar,
    7. ProfileAssociated? associated,
    8. ViewerState? viewer,
    9. List<Label>? labels,
    10. DateTime? createdAt,
    11. VerificationState? verification,
    12. StatusView? status,
    13. Map<String, dynamic>? $unknown,
    )?, {
  2. required TResult orElse(),
})

A variant of when that fallback to an orElse callback.

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return orElse();
}

Implementation

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult Function( String $type,  String did,  String handle,  String? displayName,  String? pronouns,  String? avatar, @ProfileAssociatedConverter()  ProfileAssociated? associated, @ViewerStateConverter()  ViewerState? viewer, @LabelConverter()  List<Label>? labels,  DateTime? createdAt, @VerificationStateConverter()  VerificationState? verification, @StatusViewConverter()  StatusView? status,  Map<String, dynamic>? $unknown)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _ProfileViewBasic() when $default != null:
return $default(_that.$type,_that.did,_that.handle,_that.displayName,_that.pronouns,_that.avatar,_that.associated,_that.viewer,_that.labels,_that.createdAt,_that.verification,_that.status,_that.$unknown);case _:
  return orElse();
