whenOrNull<TResult extends Object?> method

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? $default(List<int> userIds, bool all, int? concurrency, int? rpmLimit,)?)

A variant of when that fallback to returning null

It is equivalent to doing:

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

Implementation

@optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  TResult? Function(
    List<int> userIds,
    bool all,
    int? concurrency,
    int? rpmLimit,
  )?
  $default,
) {
  final _that = this;
  switch (_that) {
    case _Sub2ApiAdminBatchLimitsRequest() when $default != null:
      return $default(
        _that.userIds,
        _that.all,
        _that.concurrency,
        _that.rpmLimit,
      );
    case _:
      return null;
  }
