When I launch the app automatically and then execute 'flutter_overlay_window', I encounter an error. #70

My Flutter app crashes with the error message "java.lang.NullPointerException: Attempt to invoke virtual method 'e8.a io.flutter.embedding.engine.a.i()' on a null object reference."

// 1. Restart your phone. // 2. Launch the app. // 3. Swipe to dismiss the app and make a phone call (using the foreground_service package). // 4. The app crashes with an error from flutter_overlay_window.
