flutter
Not showing response tab under network
What version of DevTools are you on? @bkonyi will this be fixed with the 2.1.0 release?
No, this the same issue we've been having. The full fix should be available once the next Flutter beta goes out.

@kenzieschmoll @bkonyi hi... I know the response tab is buggy since the advent of the dart Dev Tool... but right now it seems the whole network intercepting is not working since the publish of the 2.1.0 version...
I swear to God I have made network request(otherwise my app won't work....)
And we have at least the requesting networking showing in the past version... what's wrong? should I update my Flutter?

Help.... what's going on... and it seems we can't select which version of the DevTool to use... it just automatically upgrade to the latest when I open the tool....
Thanks for the heads up @SeasonLeee, looks like we had a bad version constraint and we're trying to use the new network profiling RPCs when we should be using the original implementation for applications built on the stable branch. We have a fix up in https://github.com/flutter/devtools/pull/2867 and will have a patch released shortly.
@bkonyi confirm fix.
and I also have another question, what exactly is this InternetAddress indicating?
on the right panel, its content type is websocket, well, I do have websocket in our project, but it's established by third party package, and actually, the websocket is still working, but this panel only shows this InternetAddress once... assuming this InternetAddress is websocket connection...
anyway, what is it?
@SeasonLeee Hi! I have the same exact thing that you have and I don't even use or connect to any websocket server. A websocket request always happen after my http requests and it is slowing down my application's request time. Is anyone know why that websocket request happens ?
Network devtools are broken for me as well, even after upgrading Flutter to 2.10.1.
I get api response logs in my console (flutter: Http status error [403]), but the network tab stays empty.

@GunnarAK Yeah, I'm on 2.10.2 and Network devtools endlessly says "showing 0 of 0 requests" with a spinner going constantly. One thing you can do, if you're developing for the web too, is you can use Chrome DevTools to see your network traffic.
Unfortunately for me, the problem I'm dealing with happens on real device (not emulator or Chrome) so I really would like Flutter network tab to work so I can see what's going on :-(
@bkonyi I'm using Firebase. I tried the authentication module against both the local Firebase emulator (http) and against live Firebase (https) with a real device. It doesn't seem to matter if I'm running the Network DevTools tab directly in VSCode or if I run the entire Flutter DevTools in Chrome and have the Network tab open, I have them both open at the same time and neither gets any data. Also tried with iOS simulator pointed at local Firebase emulator, with Network DevTools tab open in VSCode and open in Chrome at the same time- still nothing.
I'm using Dio to make requests to https://api.igdb.com/ I'm developing for iOS and Android.
It worked for me the week prior, but when reopening the project (no new changes) it decided to not show anything. No errors in my console/terminal/VSCode, where-ever.
PS: I'm quite new to Flutter/Dart. Trying to build a relatively simple Flutter application
@jpangburn this is using the Flutter Firebase plugins, correct? I'm not 100% sure they're using the Dart HTTP implementation (they might be using the Android/iOS HTTP stacks), and if they're not, the network profiler unfortunately won't know anything about those requests. If that's the case, you should be able to use something like the Network Inspector in Android Studio.
@GunnarAK I'm also not 100% sure if Dio is using the built-in HTTP stack in dart:io. Can I trouble you to share your code for the request so I can build a reproduction case?
@jpangburn after giving a quick look at the Firebase plugins, I'm 99% sure that the network requests aren't being made through dart:io, but through the Android networking stack. As far as I can tell, the Firebase plugins are wrapping the native Android/iOS Firebase APIs.
@kenzieschmoll we should document this or investigate what it would take to get network profiling data from the native HTTP stacks into DevTools.
@bkonyi yes I’m using the plugins, and I’ve debugged into it before and they are using native platform delegates to connect. Sorry I didn’t know that this network monitor required dart io or it would have been clear why it didn’t work. Would be nice if it worked for the firebase plugins as I imagine they’re pretty popular?

@jpangburn no worries, it's not obvious that those plugins don't use dart:io or that the network profiler depends on dart:io. We definitely want to hook into more native profiling data where we can, but it's not as easy as it sounds, unfortunately. We should do a better job communicating the limitations of the network profiler at the very least... :-)
@bkonyi Requests I made from Dio programs don't show up in DevTools' network
@bkonyi Yes, as you say, it would also be nice if there was some large disclaimer that says "The Network DevTools will ONLY show traffic that comes from dart:io requests- be aware that many plugins may use native code for networking which will not show up here." Otherwise people like @jahnli, myself, and probably many others spend lots of time trying to figure out what they're doing wrong when really we should be using platform specific network monitoring tools. The current page has nothing like that, so new people are left to assume that it will just work.
I am not sure but when I restart chrome (on macos) it tentatively works for a short period of time and stops working again. There are definitely some things are going on. I disabled all my chrome extensions just to make sure but no luck. Maybe I can try to restart my computer later but this is definitely hard to reproduce all time.
Thanks
@bkonyi one week prior to my issues with the network inspector it worked. I did not make any changes to my codebase in the meantime. 😓 Due to the network inspector issues I tried upgrading Flutter hoping that would fix the issue. The upgrade was advised by my terminal output when installing the application on my Android device. Below you can find my dio implementation.

@jpangburn But he used to be perfectly able to work , it wasn't empty every time, it just popped up occasionally in Netowrk, and I think that was a problem,
I'm experiencing the same issue certain Network request are displayed inside Devtools but others don't show up
