Just reproduced your bug, and I get the following message :

Unsupported value: -65569: Defunct connection of type __SwiftNativeNSerror

It seems that we're trying to send a __SwiftNativeNSerror to the Dart side, which is causing a crash.

I also tested the example project with the following steps, and it crashed:

Open Runner.xcworkspace in Xcode
set EditScheme -> Run -> Build Configuration as Release
run the app on an iPhone Simulator
it crashes with the following message:

Hey,

Your code seems correct. Is the error detailed in #65 (comment) the same you're describing in your first message ?

from bonsoir.

ctwdtw commented on August 26, 2024

No, when using fvm flutter run -d <my_iPhone_device_id> --release I did not get a crash stack trace. the app just crashed. I may need to install Crashlytic to dump the stack trace.

I guess the crash is because of the release build, that's why I tested the example project by changing EditScheme -> Run -> Build Configuration as Release and to my surprise, it crashed right after I ran the example app.

I have pushed a repo so that you can reproduce the bug I described here #65 (comment)

https://github.com/ctwdtw/bonsoir_report

please have a look, thanks.

Just tried to reproduce the bug thanks to your repo (https://github.com/ctwdtw/bonsoir_report), but the "push to background" - "pull into foreground" sequence doesn't seem to produce any crash, in debug mode at least.

ctwdtw commented on August 26, 2024

Yes, it does not crash in debug mode. As I pointed out in step 3 of how to reproduce the bug:
fvm flutter run -d <my_iPhone_device_id> --release, it did crash on release mode with the push to background, and pull into foreground sequence.
