maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult $default(bool? noKernelTun, String secretKey, List<String>? address, List<WireGuardPeerConfig>? peers, @JsonKey.new(name: 'mtu') int? mtu, @JsonKey.new(name: 'workers') int? numWorkers, List<int>? reserved, XrayTargetStrategy? domainStrategy,)?, { 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();
}
