ios – Why is my Flutter app crashing on app give up?


When testing in iOS Simulator (through xCode) if I give up the app, it’s going to crash with the next message within the console.

Runner[8634:2415656] No home windows have a root view controller, can't save software state. Message from debugger: Terminated attributable to sign 9

When testing this on TestFlight with an actual gadget I will get the iOS popup asking to share the crash with the developer.

When testing in iOS Simulator (through Android Studio) if I give up the app, it’s going to crash with the next report.
