I have a Flutter app for both iOS and Android. Recently users started to hit white screen during launch and the app just hangs, and then they complain by leaving messages in Google Play and App Store. I am not able to locally reproduce the issue with my devices, and I did not capture any ANR (Android Not Responding) or Firebase Crashlytics events. It just hangs randomly.

I know that the above information is very limited, and I am trying to collect devices that hit the problem so that I can view the flutter log. Before this, anything else I can do to troubleshoot this random hang issue?
