/// Encodes and decodes some objects. Note that although the objects are stored
/// in a list, they are encoded and decoded separately, each one treated as a
/// top-level object. This is expected behavior for transit and is an example of
/// how transit brokers in not just one, but _streams_ of JSON objects.
Future<void> main() async {
  // Some objects to work with.
  var objects = <dynamic>[
    "hello",
    ["A", "B", null, true, 3.4],

  var transit = TransitJsonCodec();

  // Encode the objects to a List<String>;
  var encoded =
      await Stream.fromIterable(objects).transform(transit.encoder).toList();

  // Decode the objects to a List<dynamic>
  var decoded =
      await Stream.fromIterable(encoded).transform(transit.decoder).toList();
