How does this get a list of clients if it doesn't return a List?

	/**
	* Gets a list of clients.
	*
	* @return {Namespace} self
	* @api public
	*/
	clients(fn([_])) {
	this.adapter.clients(this.rooms, fn);
	this.rooms = [];
	return this;
	}

The api usage likes this.

foo.clients((sids) {
   // the sids here is a list of sockets' id
});

You can take a look at -

socket.io-dart/lib/src/adapter/adapter.dart

Line 194 in 8b05ec8

if (fn != null) scheduleMicrotask(() => fn(sids));

So does the documentation for this function need to be updated or is it fine?

according to the JS implementation here - https://github.com/socketio/socket.io-adapter/blob/master/index.js#L166
I think it's fine so far. :)
