[Web] headers in HtmlWebSocketChannel?

[tusharsadhwani]

Is there any way to provide headers to an HtmlWebSocketChannel? Right now it seems that only url and protocols are available right now.

I'm assuming this is because dart:html WebSocket doesn't allow you to do that, and I think flutter/flutter#39998 is the right place to ask about this, but is there some other thing that I'm missing?

It seems HTTP headers cannot be reliably depended upon (browser specific). So the only reliable option seems to be to establish a websocket connection and then exchange auth information in a handshake phase, before accepting any further packets.
