maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult $default(String? name, @JsonKey.new(name: 'mtu') int? mtu, List<String>? gateway, @JsonKey.new(name: 'dns') List<String>? dns, int? userLevel, List<String>? autoSystemRoutingTable, String? autoOutboundsInterface,)?, { 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
