[GSoC] WebSocket PoC built — Architectural question on the gRPC phase

[Khanak Khandelwal]

Hii Samuel and Elliott,

I'm finalizing my proposal for the Network panel WebSocket/gRPC support. I've successfully built a sample project  for the WebSocket interception using the 

_httpProfile  pattern. As I map out the gRPC phase, I'm curious about the team's preference for the interception layer. Since gRPC uses HTTP/2 multiplexing, is the goal to intercept this strictly down inside the dart:io HTTP/2 implementation, or would it be cleaner to build profiling hooks directly into package:grpc using client interceptors? 

Best regards,

Khanak Khandelwal

Hi Samuel and Elliott,

I just wanted to let you know that I have officially submitted my GSoC 2026 proposal for Add WebSocket/gRPC Support to the Flutter DevTools Network Panel.

I know you both have a mountain of proposals to read through right now. If you happen to have a moment to take a look at mine, any feedback would be greatly appreciated! Thanks again for your time.

Hi Khanak, sorry for the delay.

I think the implementation for the gRPC support would go into the gRPC Dart package, rather than down at the HTTP layer.

Hi, thanks a lot for the feedback, I really appreciate it! I’ll review the gRPC Dart package approach. If you have any other suggestions or feedback, I’d be happy to hear them.
