maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult $default(int version, String? auth, String? congestion, Bandwidth? up, Bandwidth? down, @JsonKey.new(name: 'udphop') UdpHop? udpHop, int? udpIdleTimeout, Masquerade? masquerade,)?, { 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

          Bandwidth? down,
          @JsonKey(name: 'udphop') UdpHop? udpHop,
          int? udpIdleTimeout,
          Masquerade? masquerade)?
      $default, {
