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 id,  String userId,  String topicId,  String? chunkId,  String cardType,  String front,  String back,  double easinessFactor,  int intervalDays,  int repetitions,  DateTime nextReviewAt,  DateTime? lastReviewAt,  int? lastQuality,  double? stability,  double? difficulty,  String state,  double? lastElapsedDays,  int? scheduledDays,  String algorithm,  Map<String, dynamic>? cardData)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _ReviewCardModel() when $default != null:
return $default(_that.id,_that.userId,_that.topicId,_that.chunkId,_that.cardType,_that.front,_that.back,_that.easinessFactor,_that.intervalDays,_that.repetitions,_that.nextReviewAt,_that.lastReviewAt,_that.lastQuality,_that.stability,_that.difficulty,_that.state,_that.lastElapsedDays,_that.scheduledDays,_that.algorithm,_that.cardData);case _:
