Will this support listener to specific event?

Specific event listener is necessary in some scenarios. Hope to have it.

What do you mean by "event"? A web socket is a duplex communication channel - it doesn't define anything in terms of "event".

The Stream API doc talk about "events" - in as much as you can get the stream for a web socket channel you can deal with events in any way you can with a stream, but I don't know what "specific" would mean in that context.

Perhaps you're meaning events like DOM events? In that case you'll want to look at the APIs around dart:html

I guess 'events' here might be 'exceptions'. Such as:

• connected

• disconnected

• message sent

• message send failed

connected is the onOpen event, but I didn't see any api about this in this package.

https://api.dartlang.org/stable/2.4.0/dart-html/WebSocket/onOpen.html

I don't think this package is not intended to expose the low level plumbing - for that use the WebSocket directly. This package is wrapping an existing WebSocket and exposing it as a StreamChannel.

We do expose at least a little beyond the StreamChannel interface, with things like closeCode, but I'm not sure how much we'd want to expand that...

I made an implementation here of this npm wrapper over the IOWebSocketChannel. Implements requests and messages based on events like socket.io
