Local notifications

[Sam Cromer]

I’m messing with local notifications and am trying to create scheduled ones. I get no errors but the notifications never happen . What’s the best way to debug these? I’ve stepped thru all the code and nothing throws an error message

[Rex Bloom]

Sam,

Can you share some source code?

Have you done all the required setup (in the Android and iOS projects)?

Here is the code. I had to fix sound and launcher_icon errors, at this point nothing throws an error but no notifications come thru so im assuming im missing something config wise but I have looked in the android manifest file and pub and have mirrored everything in the working demo.

 

SCHEDULE NOTIFICATION CODE

 

Future<void> scheduleNotification(Medicine medicine) async {

    var hour = int.parse(medicine.startTime[0] + medicine.startTime[1]);

    var ogValue = hour;

    var minute = int.parse(medicine.startTime[2] + medicine.startTime[3]);

 

    var androidPlatformChannelSpecifics = AndroidNotificationDetails(

      'repeatDailyAtTime channel id',

      'repeatDailyAtTime channel name',

      'repeatDailyAtTime description',

      importance: Importance.Max,

      sound: 'sound',

      ledColor: Color(0xFF3EB16F),

      ledOffMs: 1000,

      ledOnMs: 1000,

      enableLights: true,

    );

    var iOSPlatformChannelSpecifics = IOSNotificationDetails();

    var platformChannelSpecifics = NotificationDetails(

        androidPlatformChannelSpecifics, iOSPlatformChannelSpecifics);

 

    for (int i = 0; i < (24 / medicine.interval).floor(); i++) {

      if ((hour + (medicine.interval * i) > 23)) {

        hour = hour + (medicine.interval * i) - 24;

      } else {

        hour = hour + (medicine.interval * i);

      }

      await flutterLocalNotificationsPlugin.showDailyAtTime(

          int.parse(medicine.notificationIDs[i]),

          'Medication Reminder: ${medicine.medicineName}',

          medicine.medicineType.toString() != MedicineType.None.toString()

              ? 'It is time to take your ${medicine.medicineType.toLowerCase()}, according to schedule'

              : 'It is time to take your medicine, according to schedule',

          Time(hour, minute, 0),

          platformChannelSpecifics);

      hour = ogValue;

    }

    //await flutterLocalNotificationsPlugin.cancelAll();

  }

}

Not at my computer, but when your app starts what does “var pendingNotificationRequests =

        await flutterLocalNotification” give you? Does it show the notifications you have scheduled?

Also, have you added

<receiver android:name="com.dexterous.flutterlocalnotifications.ScheduledNotificationBootReceiver">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED"></action>
    </intent-filter>
</receiver>

and 

<receiver android:name="com.dexterous.flutterlocalnotifications.ScheduledNotificationReceiver" />

Cheers,

Andy

Also assuming you’ve done a very basin notification for 15 secs from “now” to see if it fires. If yes, then I guess your time calculations are wrong, if no I guess it’s configuration/permissions (and check the get all notifications to check it’s been set).

Cheers,

Andy

Thank you AndyTomG! That fixed it, I was missing the Android manifest receiver settings.

 

Im new to flutter and setting up notifications, do these notifications work when the app is NOT running as well?

 

I also need to set up push notifications for my app do you have a preference on what to use for those?

 

Thanks,

Sam

Yes, once set, local notifications still fire (happen) when the app is closed - but it’s up to the app to handle being launched (if user taps on it) from the notification (eg go to specific page).

Firebase Messaging for push notifications.

Cheers,

Andy

I too used to use firebase push notifications (FCM) - its good until you would like to send images in the notification, which show up in the notification expanded view. In my experience, the below particular use case is still not handled by fcm flutter plugin. 

• Auto Send Push Notification with Images when the app is terminated: So, when the app is closed (not running in the background) and we want to send an image-based push notification programmatically using backend like nodejs along with cloud functions, the image doesn't show up. ( fcm flutter plugin link, check receiving messages part - the message is lost)

I was not able to solve the above use case, that was the reason, I had to switch to OneSignal push notifications. I must admit the OneSignal flutter Plugin works like a charm when sending auto push image notifications (with backend nodejs and cloud functions).  Ex: Our Catholic News App integrated with OneSignal - Receives and displays auto push notifications of Latest News along with news article image. 

If image notifications is not your requirement, then fcm will suffice. 

NB: disclaimer not associated with OneSignal :)
