Flutter IOS App crash in background

[dev-junaid-khan]

I am using this plugin to download a large number of files, and it works fine on both iOS and Android platforms. However, recently I have been facing a crash issue when the iOS app goes into the background.

Hello,
I have a somehow similar issue, I will also create a new issue post as I'm now concerned about the Android version of my app, as I started to use this package to solve an "issue" on Android .. if users use the CLOSE ALL button in Android Recent Apps, my app should continue recording the track user started recording. But since I introduced this package, it crashes my iOS app ONLY WHEN THE APP STAYS IN THE BACKGROUND, not recording a track, when it stays idle , in the background. And another important clue, it does not crash if the phone is in DO NOT DISTURB mode. But it does crash multiple times in FOCUS mode

I have DND mode active from 23 to 7:00 , yesterday I woke up late at 8:56, immediately after I received an whatsapp notification, turned on the screen, tapped the WA notification and the screen was flooded with like 6 or 7 notifications that my app crashed.

It never happens when the app records a track for hours, no crashes, but it also doesn't use this service on iOS, only on Android.

Any clues , any hints from any one are welcome. After I will fix the Android issue with your help hopefully, will dig more into the ios bug (the app records gps position correctly for the first track, but if user stops & saves the track, than start another recording, it can't reconnect .... ForegroundServiceDidNotStartInTimeException on second startService() call — flutter_foreground_task 9.2.2)
