when<TResult extends Object?> method

@optionalTypeArgs TResult when<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,))

A switch-like method, using callbacks.

As opposed to map, this offers destructuring. It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case Subclass2(:final field2):
    return ...;
}
