Support .map() that returns ResponseStream instead of Stream

[maherjaafar]

keeping the return type as ReponseStream to be able to call .cancel() after using .map()

Used version: grpc: 3.2.4

Example

    final myStream = _client
        .myReponseStream
        .listen((event) => event.map((event) => event.value));

Expected result: I expect to get result of type ReponseStream but the result will be of type Stream

Actual result: Stream

Hi @maherjaafar, I am not sure what you mean. Where does this WatchEventsRequest come from?

@mosuem It's just an example. I changed it⬆️

The issue arises when I use .map, as it converts it to a Stream instead of a ResponseStream. Consequently, I lose the ability to call myResponseStream.cancel() to cancel the stream.
