Network requests in the Devtools network tab can appear to hang

[navaronbracke]

I encountered a bug where I was using the Devtools' Network tab to monitor a request, so that I could see what the request body was for the request (since logging it manually was a bit of work).

However, I had a specific request that seemed to hang in the Devtools Network tab. At first I was thinking of a bug in my code, so I added some logging to get the request status code. In my code, I see that the request successfully completes with a 200 status code (as apparent in the attached video).

However, in the Devtools Network tab, the request ends up getting a status code, the socket is closed, but the status of the request still says "Pending". That prevents me from looking at the request body / response body.

Not sure if this is related, but the response body of the actual request (when logged in my code) was null.

This is on Devtools 2.42.3

Any updates on this? Same thing happening with flutter 3.32.0

This may be fixed with the DevTools in Flutte 3.35.0 or newer. I fixed a very similar bug in March. https://github.com/dart-lang/sdk/commit/fd3eaa68318850697eb610483b8f8f866c28cdc6

Can you try with a recent Flutter and post whether the problem persists?

I cannot reproduce this on beta 3.37.0-0.1.pre, so I can assume that this is fixed.
