maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String $type,
    2. String actorDid,
    3. DateTime convoCreatedAt,
    4. String convoId,

    11. bool subjectFollowsOwner,
    12. 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 actorDid,  DateTime convoCreatedAt,  String convoId,  DateTime createdAt,  int groupMemberCount,  String groupName,  String joinLinkCode,  String ownerDid,  String rev,  bool subjectFollowsOwner,  Map<String, dynamic>? $unknown)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _EventGroupChatJoinRequest() when $default != null:
return $default(_that.$type,_that.actorDid,_that.convoCreatedAt,_that.convoId,_that.createdAt,_that.groupMemberCount,_that.groupName,_that.joinLinkCode,_that.ownerDid,_that.rev,_that.subjectFollowsOwner,_that.$unknown);case _:
  return orElse();
