The stack trace points to FlutterLocalNotificationsPlugin.java, especially setSmallIcon, createNotification, and showNotification, with ScheduledNotificationReceiver.java as the entry point. Start by reproducing a scheduled notification on Android 13 and trace the null value through these calls. Done means the receiver completes without the reported NullPointerException.
