Hey!

I am using show notification at a specific day of the week. Have made it so that it will call the function multiple time, but it seems that I have to use a different ID for each call. This will be very crowded fast with a specific day of the week notification. Some items I have would have a notification for 6 days and that would mean that I need 6 different ID:s.

Is there any better way to handle this with the plugin?

The plugin should provide the ability to specify custom notification actions. However, this will depends on the Flutter engine being able to support headless-Dart code as per flutter/flutter#6192 and flutter/flutter#3671

It appears Android support is there but will wait to see on if the engine can support it for iOS applications, and for Flutter to provide abstractions to access the functionality. Without the support being added in, then this won't work for scenarios like when the application has been terminated as the logic associated with the action would've been defined in Dart.

Update with remaining work (IMO)

• rework callbacks to deal with "foreground" and "background" notification actions. See #1489 for more detailed discussion
• potential issue with setting notification categories affecting ability to see the notification actions #1481

Note that last two perhaps could be omitted given market share and those require using deprecated APIs

Edit:

• there is headless execution on iOS but there are limitations at the moment. See flutter/flutter#23904. Upvote the issue on the Flutter repo if this concerns you to help the Flutter team prioritise
• removed tasks on supporting older iOS and macOS versions given market share and those require using deprecated APIs

There's a strange navigation issue that's likely related to the Android lifecycle and how Flutter hooks into this. This doesn't seem to be a plugin issue as it works fine on iOS and if the users taps on the notification while the Android app is terminated then it works fine as well. Delaying the execution of the navigation code also works. Raised this at flutter/flutter#16636 and suggest other developers to vote for it to be investigated

I have a Duration which is, for example, two days and four days.

Is there any way we can schedule a notification to happen every two days and every four days?

Now I am using the code below to initialize

  if( _sdkInt >= 22) {
    initializationSettingsAndroid = new InitializationSettingsAndroid('ic_notification');
  }

the white circle is my icon , I want it fill the whole circle.

Current advice is for developers using the plugin to handle the didReceiveLocalNotification method within the app delegate of their iOS head project. In theory, it should be possible to handle this within the plugin itself since the plugin is registered as an application delegate. However, the method never fires when trying to handle it within the plugin.

This has been raised on the Flutter repository flutter/flutter#16662 for the Flutter team to look into. Suggest anyone that would like the Flutter team to look into it to vote with a thumbs up as this seems to be how they prioritise looking at issues

The firebase_messaging doesn't work properly in iOS platform when we apply firebase_messaging plugin and flutter_local_notifications plugin together, but it works fine in Android platform.

Without the firebase_messaging plugin, our app works fine and can receive all of the callbacks (onMessage, onLaunch, onResume) from firebase_messaging.
Unfortunately, the callbacks don't be called once we apply the flutter_local_notifications plugin.
_firebaseMessaging.configure(
onMessage: onMessage, onLaunch: onLaunch, onResume: onResume);
Anyone can help to look into this issue?
Here is the firebase_messaging link.
https://pub.dartlang.org/packages/firebase_messaging

Has anyone tested this on ChromeOS ?

Hi,
When notification is received I want to open the app (if it's killed or in the background) and navigate to a specific view. The problem is that i don't know which build context to pass to a navigator in order this to work. The solution provided in example project is not working for me because, when I kill the app and open it by tapping on the notification I land on home view of my app and transition to other view is not occurring.

Would it be possible to add support for setOnlyAlertOnce on Android? I don't know if there's an equivalent for iOS and if it makes sense to diverge the functionality between Android and iOS.

Is it possible to set a future DateTime using "flutterLocalNotificationsPlugin.showDailyAtTime".

Example: I want to set a notification next week. After that week, I want a daily message at a specific time.

I can't find any solutions to solve my problem.

Hello,

Is there a way to configure sound and or vibrations in android when displaying the notification?

I see the IOS initial settings allow to pass a sound and badge values on initial settings but the android part only takes default icon.

Thanks

I am not sure if this is an issue with the plugin or my implementation. I am unable to schedule multiple notifications on Android correctly. I am using time in milliseconds to create new channels for each scheduled notification however they display at the wrong time. I scheduled 3 notifications at 1 minute, 3 minute, and 5 minutes. The last two showed up at the same time but showed up at 5 minutes.

Is receiver necessary for receiving android scheduled notifications, because for ios you dont need nothing else than the configuration

If this applies to android only, please do it for at least android.

Demo app seems to be working fine.
Also when I use the code within my app for showing immediate notification "_showNotification()" , it also works.

But other notifications like, show notification after 5 seconds or show notification at specific time of day are not working.

Am am missing some configuration?

I am calling _showDailyAtTime(); withing initState() function.

Future _showDailyAtTime() async {
    var time = new Time(16, 23, 0);
    var androidPlatformChannelSpecifics = new AndroidNotificationDetails(
        'your channel id', 'your channel name', 'your channel description',
        importance: Importance.Max, priority: Priority.High);
    var iOSPlatformChannelSpecifics = new IOSNotificationDetails();
    var platformChannelSpecifics = new NotificationDetails(
        androidPlatformChannelSpecifics, iOSPlatformChannelSpecifics);
    await flutterLocalNotificationsPlugin.showDailyAtTime(
        0,
        'show daily title',
        'Daily notification shown at approximately at',
        time,
        platformChannelSpecifics);
  }

@override
  void initState() {
    // TODO: implement initState
    super.initState();

    var initializationSettingsAndroid =
        new AndroidInitializationSettings('app_icon');
    var initializationSettingsIOS = new IOSInitializationSettings();
    var initializationSettings = new InitializationSettings(
        initializationSettingsAndroid, initializationSettingsIOS);
    flutterLocalNotificationsPlugin = new FlutterLocalNotificationsPlugin();
    flutterLocalNotificationsPlugin.initialize(initializationSettings,
        selectNotification: onSelectNotification);
    _showDailyAtTime();
  }

I'd like to see a feature to have a persistent / permanent Notification, that cannot be dismissed.

I myself are very new to Flutter / Dart / Mobile Development, so i wont be able to submit a PR myself (although i am very happy to help where i can).

Example use case:

My app has a offline storage for user experience. If there are changes made that are no yet pushed to the remote server-backend i like to show a permanent notification so the user is reminded he has to open the app to trigger a sync.

Using the example app, seems like ongoing notifications can still be swiped away and dismissed in the tray on Android? Is there a way to make it sticky?

if you use the latest versions of the firebase plugins you get the next error

Android dependency 'com.android.support:support-compat' has different version for the compile (27.0.1) and runtime (27.1.0) classpath.

Hi

I'm having problems configuring this for Android. Whatever I do, I can't seem to identify the icon correctly, meaning every notification throws the following crash:

java.lang.RuntimeException: Unable to start receiver com.dexterous.flutterlocalnotifications.ScheduledNotificationReceiver: java.lang.IllegalArgumentException: Invalid notification (no valid small icon): Notification(channel=FEA_NOTIFICATION pri=1 contentView=null vibrate=null sound=null defaults=0x0 flags=0x10 color=0x00000000 vis=PRIVATE)

Android setting are configured thus:

final initializationSettingsAndroid = AndroidInitializationSettings(ICON_NAME');

And I've tried every combination I can think of for ICON_NAME: app_icon, ic_launcher, ic_launcher.png, @mipmap/ic_launcher and so on.

I wonder if I'm just doing something stupid? Is there something obvious I'm missing?

Many thanks

Nic

It all works beautifully on iOS, BTW - many thanks for this.

Does the cancel and cancelAll methods cancel outstanding notification or scheduled notifications (or both)?

Problem on iOS. Android is okay.
I tried to use it with onMessage method of Firebase Messaging Plugin but it didn't work.
And I tried to remove this plugin then onMessage method of Firebase Messaging Plugin can work.

This issue i am facing when using flutter version 2.3, u have mentioned like it got fixed in flutter master channel.
can you help which files need to be modified for fixing this

So this works correctly on IOS but not on Android. The problem is that when I've used a one-time notification that will fire in, for example, 20h. When the notification pops up it says that notification came 20h ago and not now.

To clarify. I set a notification in 20h. When 20h has gone by and the notification appears it says 20h on the notification (the time when the notification appeared). On IOS, however, it displays it normally so it won't say 20h but more like 1 min etc

Hi MaikuB,
would it be possible to add a repeatInterval for monthly alarms?

I am very new to Flutter so maybe someone can help me.
When I have added this package to the pupspec.yaml the following error comes up:

FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ':app:preDebugBuild'.

Android dependency 'com.android.support:support-compat' has different version for the compile (26.1.0) and runtime (27.1.0) classpath.

Hello. I am fairly sure I am just misunderstanding the syntax, but I cannot get Notifications to show on Android.

This is my Android initialization settings:

    InitializationSettingsAndroid initializationSettingsAndroid = new InitializationSettingsAndroid('app_icon');

And when I schedule a notification, I get the following error

Caused by: java.lang.IllegalArgumentException: Invalid notification (no valid small icon): Notification(channel=DEFAULT pri=2 contentView=null vibrate=null sound=null defaults=0x0 flags=0x0 color=0x00000000 vis=PRIVATE)

No matter what I put for 'app_icon', such as a path to an image, "app_icon" itself, i still get this error. Any help would be greatly appreciated.

It would be really nice to have a callback that would be called when notification is shown.

When I add flutter_local_notifications: "^0.1.0" to pubspec.yaml, I get this error when I start my project.

app:preDebugBuild'. Android dependency 'com.android.support:support-compat' has different version for the compile (25.2.0) and runtime (27.1.0) classpath. You should manually set the same version via DependencyResolution

I resolved it by adding the below to android\build.gradle file

allprojects {
    repositories {
       //...
    }
    subprojects {
        project.configurations.all {
            resolutionStrategy.eachDependency { details ->
                if (details.requested.group == 'com.android.support'
                        && !details.requested.name.contains('multidex') ) {
                    details.useVersion "27.1.0"
                }
            }
        }
    }
}

After it was resolved, there is still this warning in Run console

I test this plugin in Android 7.1.1 , only a white square displayed.

Don't have an old iOS device to test if the code for using custom sounds works on older devices. The code looks right but the sound won't play on the simulator, which seems to be a common issue that has been reported by other iOS developers.

Be good if someone in the community could confirm it works for them unless I can source an older device for testing

When I try to use your package on an iOS device, I have this exception:

Handle exception: MissingPluginException(No implementation found for method initialize on channel dexterous.com/flutter/local_notifications)

Do you know how to deal with it?

Thanks so much for writing this plugin, it's incredibly useful. Hopefully those final issues get cleared out with flutter soon so it can be officially adopted.

Onto the not so great part, I have two different and independent notifications scheduled to be shown daily calling showDailyAtTime . One is shown in the morning, and the other in the evening. They both have unique notification ids and titles, while the body is the same.

If I schedule them to display relatively close to the current time, they will both execute and display. However the next day only the last one scheduled will display, which is the evening one in our case. The code execution is as follows:

• (await) cancel all existing notifications through plugin
• (await) schedule morning reminder
• (await) schedule evening reminder

Have you seen anything similar or know of any current issues that may cause this? Thanks.

I built the example code with no changes (flutter build apk). When I run it on my actual device (Samsung S7 Edge with Android 8.0) and click "Repeat notification every minute", I actually get a notification every 5 minutes (not every minute).

I tried the same apk on an an emulator (Pixel 2 XL API 24) and it notified every minute as expected.

Very odd.

Do you plan to support app icon notification badges for iOS and Android? :)

Or maybe I just overlooked the functionality in the current plugin. Anyhow, would love to see the feature built in.

My use case is simple for a start - when a user gets pushed a notification (scheduled) an app icon badge gets applied. A low-level starting scenario could be binary - either the badge is shown with a "1" on it no matter how many notifications have been pushed since their last open or it's not there at all.
Once the user opens either the notification or the app itself, simply expose a function to clear the badge.

Otherwise, loving the package. So awesome work 👍

Based on your examples. When application is in foreground I tap on just received notification then the Context is null. How do I navigate user to next screen?

 @override
  void initState() {
    super.initState();
    flutterLocalNotificationsPlugin = new FlutterLocalNotificationsPlugin();
    flutterLocalNotificationsPlugin.initialize(initializationSettings,
        selectNotification: onSelectNotification);
  }

 Future onSelectNotification(String payload) {
   // in this method I am missing context - it's null. So when Notification is tapped on I'd like to redirect user to specific screen. Do you know how to get context here?
    Navigator.of(context).push(new PageRouteBuilder(
          pageBuilder: (_, __, ___) => new HistorieItemScreen(),
        ));
  }

Sorry to disturb your again, If I would ignore IOS version < 10. How would I implement a day interval for notifications?

Ex: every other day, every third day, every second week?

Hi MaikuB,
I seem to be encountering an issue where when notifications are displayed and manually dismissed, upon restarting the device, when the phone boots up, all previous notifications that occurred while the phone was turned on suddenly all come in all at once. It's as if they were never really dismissed.

If I set a notification to fire at a specific time, it, fires, then I manually call "CancelNotification" on that single notification with that ID, even though this successfully removes the notification and dismisses it from the status bar, when I restart the phone, it reappears as if it were never canceled.

If I use "CancelAllNotifications" however, it does truly "cancel" it and previously dismissed notifications don't reappear upon restart, but obviously, I can continuously call "CancelAllNotifications" for a single notification because it will remove all the other unrelated notifications iv'e set up as well.

Any idea about this?

It would be nice to be able to schedule repeating notifications (something like UNTimeIntervalNotificationTrigger on iOS / AlarmManager.setInexactRepeating() on Android).

HI

Right now when you schedule a notification for a specific date time it repeats every day.

I'd like to have an option to schedule a single notification, is that possible?

I'm using:

  flutter_local_notifications: ^0.3.6

I want to schedule a notification everyday at 10 AM. But currently I depend on the time that the notification is being setted up.

What I'm thinking is the following

final now = new DateTime();
// the first notification should be on 10:00 AM, so we set that date and set a daily interval
final firstNotification = new DateTime(now.year, now.month, now.day, 10, 0);
await flutterLocalNotificationsPlugin.periodicallyShow(
        ALARM_NOTIFICATION_ID,
        ALARM_TITLE,
        ALARM_BODY,
        RepeatInterval.Daily,
        platformChannelSpecifics,
        firstNotification); // the date starting date of the notification

What do you think?

Thanks

Here is the context:
with Android Studio 3.1.3, I was able to have the dependency to
cloud_firestore: ^0.7.4
or to
flutter_local_notifications: ^0.3.6
separately, however, once I have dependencies to both
then I got the following error:

I have been trying to wrap my mind about implementing a player app control widget in a Flutter app that appears as a notification and on locked screen, it is shows basic player controls.
I was about to start thinking about implementing them myself and then I came across this plugin, please a sample code showing how to achieve might really helpful for me.
