iOS devices frequently switch between the front and back ends and the screen goes black

[leikeke]

Steps to reproduce

Pure Flutter mobile development, iOS devices, frequent switching to the current application and switching to other applications in the background

Expected results

Normal display

Actual results

The same operation for about ten times will cause the application to go black and cannot be restored. This only happens on iOS devices and not on Android devices.

It will appear on flutter3.35.3, but not on the old version 3.32.8. I upgraded directly from 3.32.8 to 3.35.3

@leikeke Can you provide the device details like device model and iOS version with which this occurs ?

Is it only occuring with your current app or with a new Flutter app as well (counter app) ?

Can you provide us a short video of this behavior ?

Without additional information, we are unfortunately not sure how to resolve this issue. We are therefore reluctantly going to close this bug for now.
If you find this problem please file a new issue with the same description, what happens, logs and the output of 'flutter doctor -v'. All system setups can be slightly different so it's always better to open new issues and reference the related ones.
Thanks for your contribution.
