When set metalLayer.presentsWithTransaction = true, and when I call nextDrawable.present() in bg thread (our rendering thread is not main thread), the app sometimes will crash with:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Modifications to the layout engine must not be performed from a background thread after it has been accessed from the main thread.'
Expected: App will not crash....The rendering should be ok.
Stack trace:
Fatal Exception: NSInternalInconsistencyException
Modifications to the layout engine must not be performed from a background thread after it has been accessed from the main thread.

This error occurs, when i use background location updates (package background_location: ^0.4.3), to determine the users location and show the location on a flutter map (flutter_map: ^0.12.0).
HAve anybody an idea, what this error means, and how to resolve/avoid it? Thanks for any help!
Just today I also encountered the same problem as you. At present, it seems that it is caused by the Flutter SDK. It seems that the official has not found a specific solution. You can track the problem from here.
https://github.com/flutter/flutter/issues/76772
Same thing happened to me. Very weird and cannot reproduce or investigate this.

I have an app developed in Flutter, I track its crashes by Firebase Crashlytics.
According to it in 99% of the time it is crash free, but during 1% of the sessions on IOS I have a strange crash at startup of the app.

Do you have similar experiences? Is there any way to fix it?
Thanks a lot!
I do my own error handling by catching any exceptions and logging them manually. I use NSSetUncaughtExceptionHandler(&myExceptionHandler); and log the stack trace using [NSException callStackSymbols]. Up until recently my logs contained the symbolicated stack trace. Now they don't and there weren't any code changes related to the logging. This is occurring on all devices and versions of iOS. I am able to manually symbolicate my logs but it is quite cumbersome. Any insight would be greatly appreciated.
Previously my logs looked like:

Looks like Apple now performs a kind of repackaging and eventually stripping debug info.
