Dart/Flutter processes left orphaned after IDE was closed #5155
Description
Describe the bug
Dart daemon was left hanging when IDE was closed.
To Reproduce
Steps to reproduce the behavior:
- In the terminal, I ran
flutter build appbundle. - While it was loading, I started a debug session of my Flutter app.
- Building completed from the terminal.
- After waiting longer than usual, "Running gradle assemble debug" message would not leave and at the debug console it got stuck with "Launching lib\main.dart on PHONE in debug mode..." even when the app on my phone had already started and I was able to use it completely fine.
- I tried to terminate the debug session with multiple clicks to the stop button, no use because of some bug.
- Closed the IDE instead.
- Opened Task Manager and saw that
dart.exe daemonwas still running.
Expected behavior
No dart.exe left running.

Aditional info
Not completely sure, but I've seen a similar behaviour with a dart.exe (not sure it was the daemon) left hanging after the IDE got closed. Most of the time I saw this when opening two different Dart projects in two different instances of VSCode.
I was advised in Discord to enable the log for the daemon (and others) in VSCode. Will do and update this issue if that happens again.
Maybe it has something to do with concurrent analysers or something along these lines?
