Network view loses network calls
I haven't found any pattern when this happens but regularly I have the problems when trying to debug a backend issue that either the network view stops recording and event or that it only records some events and most often exactly the one I am interested in is missing so that I have to switch to an external proxy debugger like fiddler.
We use the new native HttpClients on iOS and Android, I don't know if that might have an effect.
Can you please share the version of DevTools you are using?
You can check it by running:
flutter --version
Also just suggesting a temporary workaround (Using FVM or you may use any similar tool), so that you may not have to switch to other tools for this.
While this might not be the ideal solution, you can try the following workaround to unblock yourself until a proper fix is available:
With FVM, you can use a different Flutter version without changing the version for your project.
-
Install FVM
Follow the installation steps here: Install FVM -
Install an older Flutter version (try the version that works best for you)
fvm install 3.27.3 -
Launch DevTools using FVM
You can run either of the following:fvm dart devtools -
Use DevTools for Debugging
Once DevTools launches in the browser, paste the DevTools URL (printed in your logs) into it to begin debugging.
Note:
Once the issue is resolved, you can use Devtools with usual way and switch back to the updated Flutter version to stay on the latest stable release.
I have seen the same kind of behavior as mentioned by @escamoteur . The scenario to "break" the network tab is unclear, but it seems to consistently fail to log any network requests after a hot restart. We also have some more random issues of network calls being logged and all of a sudden nothing appears anymore, but there is no clear pattern for these scenarios

Edit: Regarding the hot restart issue I found this comment https://github.com/flutter/devtools/issues/9203#issuecomment-3012866703 and the workaround seems to help a lot in my case
The exact same issue happening to us. After hot restart, the network calls do not show up anymore.
@davor-layer-four and @Miiite, I fixed an issue with missing network requests after Hot Restart with https://github.com/flutter/devtools/pull/9271. This should be fixed with the DevTools in Flutter 3.35.0.
@escamoteur can you say whether you still see intermittent missing requests when using DevTools from Flutter 3.35.0? Thank you much!
