maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String $type,
    2. String src,
    3. @USubjectViewSubjectConverter() USubjectViewSubject subject,
    4. @EnforcementViewConverter() EnforcementView enforcement,
    5. @AppealViewConverter() AppealView? appeal,
    6. @SubjectViewAvailableActionsConverter() List<SubjectViewAvailableActions>? availableActions,
    7. @ActionViewConverter() ActionView? latestAction,
    8. int? actionCount,
    9. @JsonKey.new(toJson: iso8601) DateTime createdAt,
    10. @JsonKey.new(toJson: iso8601) DateTime updatedAt,
    11. 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 src, @USubjectViewSubjectConverter()  USubjectViewSubject subject, @EnforcementViewConverter()  EnforcementView enforcement, @AppealViewConverter()  AppealView? appeal, @SubjectViewAvailableActionsConverter()  List<SubjectViewAvailableActions>? availableActions, @ActionViewConverter()  ActionView? latestAction,  int? actionCount, @JsonKey(toJson: iso8601)  DateTime createdAt, @JsonKey(toJson: iso8601)  DateTime updatedAt,  Map<String, dynamic>? $unknown)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _SubjectView() when $default != null:
return $default(_that.$type,_that.src,_that.subject,_that.enforcement,_that.appeal,_that.availableActions,_that.latestAction,_that.actionCount,_that.createdAt,_that.updatedAt,_that.$unknown);case _:
  return orElse();
