maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String? cursor,
    2. @GroupConverter() List<Group> groups,
    3. @JsonKey.new(toJson: iso8601) DateTime? seenAt,
    4. @UNotificationGetGroupedNotificationsRelatedViewsConverter() List<UNotificationGetGroupedNotificationsRelatedViews>? relatedViews,
    5. 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? cursor, @GroupConverter()  List<Group> groups, @JsonKey(toJson: iso8601)  DateTime? seenAt, @UNotificationGetGroupedNotificationsRelatedViewsConverter()  List<UNotificationGetGroupedNotificationsRelatedViews>? relatedViews,  Map<String, dynamic>? $unknown)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _NotificationGetGroupedNotificationsOutput() when $default != null:
return $default(_that.cursor,_that.groups,_that.seenAt,_that.relatedViews,_that.$unknown);case _:
  return orElse();

}
