Feature request: Please add webSocket support in network inspector

[KeterVM]

Hi Flutter DevTools team,

While using DevTools to debug my Flutter applications, I've found that it currently lacks the ability to inspect WebSocket connections. This has made it difficult for me to debug Flutter apps that rely on WebSocket.

Would you consider adding this feature in a future release? With a WebSocket connection inspection feature, we would be able to better understand the status of WebSocket connections in our apps and the data being transmitted, which would be very helpful for debugging these types of Flutter applications.

I hope you can implement this feature soon, thank you!

@bkonyi could you comment on what it would take to access data from web socket network traffic?

This would be quite a bit of work as we'd have to add network profiling support in dart:io at the very least. If we wanted to add generic support we'd have to update our HTTP profiling solution to also handle websocket traffic. cc @brianquinlan @derekxu16

Hi @bkonyi,

My name is Yash (VictoWolf) ,
I am currently exploring this project under GSOC 2026.

Right now, HTTP profiling is request-based, whereas WebSocket is connection-based and long-lived.

If we move toward a generic profiling model that supports both request-based (HTTP) and connection-based (WebSocket) protocols, what safe design measures should I keep in mind to avoid breaking the current system?

Thanks
