App crashes after 20s without any output

After a pretty big refactoring of our app ND our backend API I’m currently with the problem that the app just terminates with a “connection list to device” on the android emulator.
No exception, no log messages. Also nothing reaches Sentry. Unfortunately I cannot run it with brek on all exceptions because of this bug in the Dart network layer OS Error: No address associated with hostname, errno = 7 · Issue #54580 · dart-lang/sdk · GitHub

I tried to run it with active memory monitor but couldn’t see any dramatic changes there.
Any idea what I could try to get more information what’s going on?

Maybe with flutter run -v you can see more interesting logs

I tried but that only increases the logs while building not what you get during execution

ok, I now get sometimes the same output as this issue here
