To Reproduce

Go to firebase cloud messaging
Click on send test message

Sample code to reproduce the problem import 'dart:math';

import 'package:app_settings/app_settings.dart'; import 'package:firebase_messaging/firebase_messaging.dart'; import 'package:flutter/cupertino.dart'; import 'package:flutter_local_notifications/flutter_local_notifications.dart';

class NotificationServices { FirebaseMessaging messaging = FirebaseMessaging.instance; final FlutterLocalNotificationsPlugin _flutterLocalNotificationsPlugin = FlutterLocalNotificationsPlugin();

void requestNotificationPermission() async { NotificationSettings settings = await messaging.requestPermission( alert: true, announcement: false, badge: true, carPlay: false, criticalAlert: false, provisional: false, sound: true, ); if (settings.authorizationStatus == AuthorizationStatus.authorized) { print('User granted permission'); } else if (settings.authorizationStatus == AuthorizationStatus.provisional) { print('User granted provisional permission'); } else { AppSettings.openAppSettings( type: AppSettingsType.notification, ); } }

void initLocalNotifications( BuildContext context, RemoteMessage message) async { var androidInit = AndroidInitializationSettings('@drawable/ic_launcher'); var iosInit = DarwinInitializationSettings();

var initSettings = InitializationSettings(
  android: androidInit,
  iOS: iosInit,
);

await _flutterLocalNotificationsPlugin.initialize(initSettings,
    onDidReceiveNotificationResponse: (payload) {});

}

void firebaseInit() { FirebaseMessaging.onMessage.listen((message) { showNotification(message); }); }

Future showNotification(RemoteMessage message) async { AndroidNotificationChannel channel = AndroidNotificationChannel( Random.secure().nextInt(1000).toString(), 'High Importance Notifications', description: 'This channel is used for important notifications', importance: Importance.max, playSound: true, enableVibration: true, ); var androidDetails = AndroidNotificationDetails( channel.id, channel.name, channelDescription: channel.description, importance: Importance.max, playSound: true, enableVibration: true, ticker: 'ticker', );

DarwinNotificationDetails iosDetails = DarwinNotificationDetails(
  presentAlert: true,
  presentBadge: true,
  presentSound: true,
);

var platformChannelSpecifics = NotificationDetails(
  android: androidDetails,
  iOS: iosDetails,
);

Future.delayed(Duration.zero, () {
  _flutterLocalNotificationsPlugin.show(
    0,
    message.notification!.title.toString(),
    message.notification!.body.toString(),
    platformChannelSpecifics,
  );
});

}

Future<String?> getDeviceToken() async { return await messaging.getToken(); }

//if token refresh void onTokenRefresh() async { messaging.onTokenRefresh.listen((event) { event.toString(); }); } }
