Flutter (Channel beta, 3.13.0-0.4.pre) hangs when backgrounding app and locking phone, then coming back. #132666
Description
Is there an existing issue for this?
- I have searched the existing issues
- I have read the guide to filing a bug
Steps to reproduce
Whenever I go a few screens into my app, background the app, lock the device, and come back, there is a high chance the app hangs.
Unfortunately I cannot reproduce on a sample app. So some part of this might be my app or a library. But I provide a screenshot below.
It should also be noted I tested 3.10. Doesn't happen there. So it was a change between 3.10 and 3.13 beta.
Expected results
No hang.
Actual results
The app hangs. No error. Nothing I can actionably do at the moment.

Screenshots / Video demonstration
When running the app on xcode, I can pause to see the threads. The problem is a lot of it is machine codes. It's hard to decipher anything.
Logs
Logs
No logs, which is the problem. Just a hang.
