About Request and StreamedRequest

[glanium]

There are Request and StreamedRequest in http package.

What does streaming mean in the context of this http package?
I think streaming means something like transferring bytes in chunks in the context of http.
However, cronet_http does not support sending request bodies in chunks.
So i think when passing in StreamedRequst, it should raise Exception.

  @override
  Future<StreamedResponse> send(BaseRequest request) async {
    if (_isClosed) {
      throw ClientException(
          'HTTP request failed. Client is already closed.', request.url);
    }
    if (request is StreamedRequest) {
      throw Exception('not support');             // <-- here
   }

    _engine ??= CronetEngine.build();

    final stream = request.finalize();
    final body = await stream.toBytes();           //  <--- this is not streaming. all data in memory.
    final responseCompleter = Completer<StreamedResponse>();
    final engine = _engine!._engine;

By raising excepption, developer will know this library does not support chunk transfer.
