I am using "Firebase Cloud Messaging" for receiving notifications and "flutter_local_notifications" plugin to configure and display them on my device. So my current scenario is when my app is running (in foreground), I am receiving proper notification as expected (a pop-up plus it gets stored in system-tray) like this :
It also gets stored in the system tray as expected.
But when I keep the app in background and post a notification request ........ It just stores the notification in the tray but doesnt show a pop-up notification. Like this :
As seen in the image above .... it just stores the notification in the image tray but doesn't show pop-up notification like when the app is running in foreground.
I thought I was an issue in the "backgroundMessage" Callback but what I observed was whenever I posted a notification when the app is in background, instead of executing the "backgroundMessage" callback it always gave this exception :
W/FirebaseMessaging(22744): Missing Default Notification Channel metadata in AndroidManifest. Default value will be used.
Below is the code where I configured the FirebaseMessaging instance :
_firebaseMessaging.configure(
onMessage: notification,
onBackgroundMessage: notificationBack,
);
'notification' Callback :
Future<dynamic> notification(Map<String,dynamic> message) async {
AndroidNotificationDetails androidNotificationDetails =
AndroidNotificationDetails(
'Channel ID', 'Channel title', 'channel body',
priority: Priority.High,
importance: Importance.Max,
ticker: 'test');
IOSNotificationDetails iosNotificationDetails = IOSNotificationDetails();
NotificationDetails notificationDetails =
NotificationDetails(androidNotificationDetails, iosNotificationDetails);
await _flutterLocalNotificationsPlugin.show(
0, 'Notification', 'New Notification', notificationDetails);
}
'notificationBack' callback :
static Future<dynamic> notificationBack(Map<String,dynamic> message) async {
AndroidNotificationDetails androidNotificationDetails =
AndroidNotificationDetails(
'Channel ID', 'Channel title', 'channel body',
priority: Priority.High,
importance: Importance.Max,
visibility: NotificationVisibility.Public,
ticker: 'test');
IOSNotificationDetails iosNotificationDetails = IOSNotificationDetails();
NotificationDetails notificationDetails =
NotificationDetails(androidNotificationDetails, iosNotificationDetails);
await _flutterLocalNotificationsPluginBack.show(
0, 'Hello there', 'please subscribe my channel', notificationDetails);
}
AndroidManifest.xml :
Sorry for the screenshot instead of text format .... but I dont know why all these terms were highlighted in red saying "Cant resolve symbol ...." and "Unresolved package 'flutterlocalnotifications'" in case of reciever of flutterlocalnotification.
My main goal is to get the game pop-up notification and one in the system tray even when the app is in background. (Just how it displayed when it was in foreground).
I know the question is a bit long but I had to provide all my observation about the issue so please bare with it :)
Thankyou in advance for the help.

anybody knows how to set local notification to show everyday another notification but with the same title cause with my code i get only the same notification body over and over again. I'm struggling for some days working on it. Anybody knows how to make it work?
Here's my notification code:
Future<void> showNotification(int id, String title, String body) async {
await flutterLocalNotificationsPlugin.periodicallyShow(
id,
title,
body,
RepeatInterval.everyMinute,
const NotificationDetails(
// Android details
android: AndroidNotificationDetails('main_channel', 'Main Channel',
channelDescription: "ashwin",
importance: Importance.max,
priority: Priority.max),
// iOS details
iOS: DarwinNotificationDetails(
sound: 'default.wav',
presentAlert: true,
presentBadge: true,
presentSound: true,
),
),
androidAllowWhileIdle:
true, // To show notification even when the app is closed
);
}
I want to schedule different notification when notification it s called.
I saw different question regarding this topic like this one:
Flutter send local notification when app is closed (alarm)
Some of them with accepted answers but nothing seems to work with latest version. Notification package has changed and all of these examples are deprecated.
I tried actual version (flutter_local_notifications: ^12.0.0) and as soon as I close the app I don't receive any notification at all.
const AndroidNotificationChannel channel = AndroidNotificationChannel(
'high_importance_channel', // id
'High Importance Notifications', // title
importance: Importance.high,
);
var detroit = tz.getLocation('America/Detroit');
var now = tz.TZDateTime.now(detroit);
await _flutterLocalNotificationsPlugin.zonedSchedule(
0,
'scheduled title',
'scheduled body',
tz.TZDateTime.now(now.location).add(const Duration(seconds: 5)),
NotificationDetails(
android: AndroidNotificationDetails(
channel.id,
channel.name,
),
),
androidAllowWhileIdle: true,
uiLocalNotificationDateInterpretation:
UILocalNotificationDateInterpretation.absoluteTime,
);
The only notifications that I implemented in the background are the ones coming from firebase cloud functions, but I don't want to rely on this for simple notifications (specially because of the plan).
Is there anything working out there?
This was already working. The trick was to not test on debug:
flutter run --release
I want to open the application automatically when a firebase notification is received, without user interaction. means when my application is killed or in the background and when the user receives a firebase notification the application should open automatic without user interaction or clicking on the notification is this possible in the flutter
I want to add this feature in the video calling application that when I receive a notification the call screen with accept reject button should render and I also want to add the autoanswer feature in it.
You can achieve this in Android but Its not possible in iOS for now, For android its Full-screen intent notifications and for iOS most you can do is set an custom ringtone when notification is received, You can use the below mentioned library for most of your notification needs:-pub.dev/packages/flutter_local_notifications
yes, obviously it's possible
u can do like this
demo video link : click here for watch video
Future<void> _showNotification() async {
const AndroidNotificationDetails androidPlatformChannelSpecifics =
AndroidNotificationDetails(
'your channel id',
'your channel name',
channelDescription: 'your channel description',
importance: Importance.max,
priority: Priority.high,
icon: '#mipmap/ic_launcher',
// playSound: false,
);
const NotificationDetails platformChannelSpecifics = NotificationDetails(
android: androidPlatformChannelSpecifics,
);
await flutterLocalNotificationsPlugin.show(
0,
'plain title',
'plain body',
platformChannelSpecifics,
payload: 'item x',
);
}
Hello I need to make local notification on mobile whenever a button is pressed. And i don't want to make the notification instantly but after one hour when the user hit that button does anyone have any idea?
I tried this plugin flutter_local_notifications: ^8.2.0
But can some help me how to do the trigger after one hour
Thanks
Use this function to call notifications every hour
shownotifications() async {
const AndroidNotificationDetails androidPlatformChannelSpecifics =
AndroidNotificationDetails('repeating channel id',
'repeating channel name', 'repeating description');
const NotificationDetails platformChannelSpecifics =
NotificationDetails(android: androidPlatformChannelSpecifics);
await FlutterLocalNotificationsPlugin().periodicallyShow(0, 'Test title',
'test body', RepeatInterval.hourly, platformChannelSpecifics,
androidAllowWhileIdle: true);
}
and follow this article step by step to to setup the package you are using
I want to show push notification to user in every 30 minutes but Flutter Local Notification Plugin has limitation that it supports the repeat intervals (EveryMinute, Hourly, Daily, Weekly).
What are the alternative that I can approach to?
How about you use Timer and Flutter Local Notificaion Plugin like below?
Timer.periodic(Duration(minutes: 30), () {
// Make a local notification
var androidPlatformChannelSpecifics = AndroidNotificationDetails(
'your channel id', 'your channel name', 'your channel description',
importance: Importance.Max, priority: Priority.High, ticker: 'ticker');
var iOSPlatformChannelSpecifics = IOSNotificationDetails();
var platformChannelSpecifics = NotificationDetails(
androidPlatformChannelSpecifics, iOSPlatformChannelSpecifics);
await flutterLocalNotificationsPlugin.show(
0, 'plain title', 'plain body', platformChannelSpecifics,
payload: 'item x');
});
