Flutter android alarm manager plus works in emulator periodically but not working in real device? - flutter

Question

I am using flutter android alarm manager package to get local notifications periodically. It's working perfectly in the emulator but when I am generating an apk file and installing the app in a real android device through that apk file it's not showing any notification.
So, could anyone please help me sharing your precious experience. Thanks in advance!
Here you go with my code -
Future<void> notify() async {
try {
await Quote.saveNewQuote();
} catch (e) {
print(e.toString());
}
AwesomeNotifications().createNotification(
content: NotificationContent(
id: 1,
channelKey: 'basic_notification',
title: 'Notification',
body: 'Android alarm manager periodical notification',
));
// await Quote.notifyLastQuote();
}
void main() async {
WidgetsFlutterBinding.ensureInitialized();
await AndroidAlarmManager.initialize();
await AwesomeNotifications().initialize('resource://drawable/fitjerk_logo',
[
NotificationChannel(
channelKey: 'basic_notification',
channelName: 'FitJerk Motivation',
channelDescription: "FitJerk Today Notification ",
defaultColor: primaryDeepColor,
importance: NotificationImportance.High,
ledColor: Colors.white,
playSound: true,
enableLights: true,
enableVibration: true
)
]);
await AndroidAlarmManager.periodic(const Duration(hours: 24), 1, notify,
///TODO: here will set startAt time///
startAt: DateTime(DateTime.now().year, DateTime.now().month, DateTime.now().day, 8, 30),
exact: true, wakeup: true, allowWhileIdle: true, rescheduleOnReboot: true);
And here is my AndroidMenifest.xml
