Hi @shantaly Thank you for opening an issue;
Please give the whole scenario (step by step) to reproduce the bug. If it is possible a video would help a lot;
@mehdok ... steps to reproduce
- run background locator on iOS14
- stop it
- close the app and try to start the app again
- app is crashing before splash screen inside the AppDelegate.swift method
if I remember right - XCode is showing message "Trying to send message before Flutter engine is running" Flutter 2.2.2
