flutter_local_notifications does not show the notification(IOS only) - ios

Question

i am beginner in flutter. I try to make an app which should notify users on scheduled time. I decided to use flutter_local_notification.
(I am trying to implement this only IOS as first step so that is why code blocks related with android commented in.)
class NotificationHelper {
FlutterLocalNotificationsPlugin
flutterLocalNotificationsPlugin =
FlutterLocalNotificationsPlugin();
initializeNotification() async {
//tz.initializeTimeZones();
final IOSInitializationSettings initializationSettingsIOS =
IOSInitializationSettings(
requestSoundPermission: false,
requestBadgePermission: false,
requestAlertPermission: false,
onDidReceiveLocalNotification: onDidReceiveLocalNotification
);
// final Android InitializationSettings initializationSettingsAndroid =
// Android InitializationSettings("appicon");
final InitializationSettings initializationSettings =
InitializationSettings(
iOS: initializationSettingsIOS,
);
await flutterLocalNotificationsPlugin.initialize(
initializationSettings,
onSelectNotification: selectNotification);
}
onDidReceiveLocalNotification(
int id, String? title, String? body, String? payload) async {
// display a dialog with the notification details, tap ok to go to another page
// showDialog(
// //context: context,
// builder: (BuildContext context) => CupertinoAlertDialog(
// title: Text(title),
// content: Text(body),
// actions: [
// CupertinoDialogAction(
// isDefaultAction: true,
// child: Text('Ok'),
// onPressed: () async {
// Navigator.of(context, rootNavigator: true).pop();
// await Navigator.push(
// context,
// MaterialPageRoute(
// builder: (context) => SecondScreen(payload),
// ),
// );
// },
// )
// ],
// ),
// );
}
Future selectNotification(String? payload) async {
if (payload != null) {
print('notification payload: $payload');
} else {
print("Notification Done");
}
}
void requestIOSPermissions() {
flutterLocalNotificationsPlugin
.resolvePlatformSpecificImplementation<
IOSFlutterLocalNotificationsPlugin>()
?.requestPermissions(
alert: true,
badge: true,
sound: true,
);
}
displayNotification({required String title, required String body}) async {
print("doing test");
const AndroidNotificationDetails androidPlatformChannelSpecifics =
AndroidNotificationDetails('your channel id', 'your channel name',
channelDescription: 'your channel description',
importance: Importance.max,
priority: Priority.high,
ticker: 'ticker');
const NotificationDetails platformChannelSpecifics =
NotificationDetails(android: androidPlatformChannelSpecifics);
flutterLocalNotificationsPlugin.show(
12345,
"A Notification From My Application",
"This notification was sent using Flutter Local Notifcations Package",
platformChannelSpecifics,
payload: 'data');
}
}
and i call the initializeNotification() function on my main.dart like this:
void main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp(
options: DefaultFirebaseOptions.currentPlatform,
);
NotificationHelper().requestIOSPermissions();
NotificationHelper().initializeNotification();
runApp(const MyApp());
}
and after user logged in,
I just try to see my notification so i call displayNotification() on a button like this:
IconButton(
icon: const Icon(Icons.settings),
onPressed: () {
NotificationHelper().displayNotification(title: 'title', body: 'hede');
},
color: Colors.white,
iconSize: 25,
),
and also i call this code in AppDelegate.swift
import UIKit
import Flutter
#UIApplicationMain
#objc class AppDelegate: FlutterAppDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
}
GeneratedPluginRegistrant.register(with: self)
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}
}
when application opens it successfully asks permissions for send notifications. After it allowed i just try to call displayNotification() but it doesn't work. I cannot see any notification on my simulator.
environment:
sdk: ">=2.15.1 <3.0.0"
flutter_local_notifications: ^9.3.3
What should i do ? Thank you for you all your answers.

I think notifications doesn't work currently on İOS simulator. You should try real ios device
