[Flutter] flutter - FCM notification appears twice when app is in background

I am working on firebase messaging for handling background message with FlutterLocalNotificationsPlugin but I received two notification when I do this. I received 1 notification is from FlutterLocalNotificationsPlugin and other one is from system notification. I need to use FlutterLocalNotificationsPlugin notification because I need to do some customization, how do I disable system default notification?

void main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
await init();
FirebaseMessaging.onBackgroundMessage(firebaseMessagingBackgroundHandler);
await setupFlutterNotifications();
runApp(const MyApp());
}

@pragma('vm:entry-point')
Future<void> firebaseMessagingBackgroundHandler(RemoteMessage message) async {
await Firebase.initializeApp();
await setupFlutterNotifications();
print('Application background message: $message');
final title = message.notification!.title;
final body = message.notification!.body;
await notificationService.notification(message);
}


Future<void> notification(RemoteMessage message) async {
RemoteNotification? notification = message.notification!;
flutterLocalNotificationsPlugin.show(
notification.hashCode,
notification.title,
notification.body,
const NotificationDetails(
android: AndroidNotificationDetails(
'channel id',
'your channel name',
channelDescription: 'your channel description',
icon: 'launch_background',
),
),
);
}




I am using laravel-notification-channels/fcm for my fcm notification. My solution for my issue is to comment out fcm setNotification function. Refer to my code below are example.

public function toFcm($notifiable)
{
return FcmMessage::create()
->setData([
'title' => json_encode($this->newMessage['title']),
'body' => json_encode($this->newMessage['body']),
])
// ->setNotification(\NotificationChannels\Fcm\Resources\Notification::create()
// ->setTitle($this->newMessage['title'])
// ->setBody($this->newMessage['body'])
// // ->setImage($this->newMessage['user']['image'])
// )
->setAndroid(
AndroidConfig::create()
->setFcmOptions(AndroidFcmOptions::create()->setAnalyticsLabel('analytics'))
->setPriority(AndroidMessagePriority::HIGH())
// ->setNotification(AndroidNotification::create()->setChannelId('high_importance_channel'))
)->setApns(
ApnsConfig::create()
->setFcmOptions(ApnsFcmOptions::create()->setAnalyticsLabel('analytics_ios'))
);
}
