Pls,Support push notification for event call when Application is close / on background. about connectycube-flutter-samples

[TatankaConCube]

Yes, we plan to add background calls support in one of near release.

[nguyenquyettienktmt]

Yeahhhh, I love U 3000 <3

[StanevPrime]

+1 for this awesome feature as this is essential for each VoiP App :)

[najibghadri]

Is there a way to implement this with the current API? In a background process for example with the workmanager plugin perhaps?

[TatankaConCube]

hello guys, we updated our Push Notifications documentation for Flutter. You can try use it to implement Push notifications to your Flutter projects before we implement it in our sample.

[shivanijha002]

I am trying to use Push notification for Android however, it is not working as expected.
code sample:

Result:

Notification: title and body should not be null. How can I set these values?

Also, I do not get any notification on device. Though message is getting captured in debug console.
If I send dummy message from FCM console, my device do get alert but not from Connectycube 'Push Notifications'-> 'Send' console.

[TatankaConCube]

@shivanijha002

Notification: title and body should not be null. How can I set these values?

For the Android platform, you have to set them to the parameters map, for iOS you can use some additional parameter from our API. Note: ConnectyCube server always sends GCM with 'data' type, not 'notification'.

Also, I do not get any notification on device. Though message is getting captured in debug console.

For Android, it is expected behavior. You have to do it yourself. For example, you can use flutter_local_notifications plugin for it.
For iOS, it is a system feature and the system does it instead of you.

Thank you for the details. It might be useful if you can add it in your documentation. I wasted 2 days trying out different things and hoping it will work without anything external.
flutter_local_notifications has worked for me on Android.

@shivanijha002

Please, give me suggestion how to get notification using flutter_local_notifications for Push notification.

I got below error:

 Invalid argument(s): Failed to setup background message handler! `onBackgroundMessage`
 should be a TOP-LEVEL OR STATIC FUNCTION and should NOT be tied to a
 class or an anonymous function.

Hello @TatankaConCube

• How to get pushToken in subscription for push notification?

parameters.pushToken = "2b6f0cc9...4b831186";

• push token is static or dynamic?

• deviceId is static or dynamic and also how can I get It?

I get device id is this way using device_info: ^0.4.2+9 package and below method.

Future<String> _getId() async {
    var deviceInfo = DeviceInfoPlugin();
    if (Platform.isIOS) {
      // import 'dart:io'
      var iosDeviceInfo = await deviceInfo.iosInfo;
      return iosDeviceInfo.identifierForVendor; // unique ID on iOS
    } else {
      var androidDeviceInfo = await deviceInfo.androidInfo;
      });
      return androidDeviceInfo.androidId; // unique ID on Android
    }
  }

Is this right way or I have to implement other method?

• When I send notification It registerd on dashboard but it displays in falied status.

So, help me to solve this issue.

[TatankaConCube]

How to get pushToken in subscription for push notification?

you have to use flutter plugins for this, in our documentation, we provided the needed code for this.

push token is static or dynamic?

it can be changed during the app work, please, see our documentation, how to get the current token, and how to subscribe to its changes.

deviceId is static or dynamic and also how can I get It?

it is a static unique identifier for your device on the ConnectyCube server. You provided the correct code for getting it.

When I send notification It registerd on dashboard but it displays in falied status.

need more details about this issue:

• which error present in failed log?
• have some receivers subscription in the Connectycube admin panel?
• for which platform (Android or iOS) do you send notification?
• how you send notification (via API from app or from Admin panel)?

- have some receivers subscription in the Connectycube admin panel?
Yes.

- for which platform (Android or iOS) do you send notification?
Android

- how you send notification (via API from app or from Admin panel)?
I follow step to integrate notification.

I want to send send using firebase with your dashboard.

[Significantinfotech2020]

Hello @TatankaConCube

I want to use notification functionality in chat application. I implemented this functionality using your connectycube_sdk package. I follow each and every steps to do this functionality and also I successfully implemented this functionality. But in this code I face one issue is that when user is offline or not in the dialog page I can't get notification. In terminal there is no any error display. Every API from your server is called successfully and it displays log of generated notification. When I push on send button notification generates which displays in connecty_cube dashboard. Also device is registered in Push Notification -> Device subscription panel. Every notification displays in Push Notification -> Queue panel. but in this panel Start date, End date, Period are not displayed. When I click on status I get this issue in log received error (Failed to deliver to all recipients. Errors: InvalidRegistration). So I can't get receiver for notification. I use android device for notification. I also link my application with firebase, but in firebase console -> cloud messaging there is no any data display for notification. Please help me to solve this issue asap. I also displays image in above comment. Please check it.

this is log.

There are descriptions of possible errors on sending push notifications from Connectycube server to FCM. Looks like you have the wrong (or expired) token in the subscription. Try delete the subscription from the admin panel and create a new one, then try to send push notification again.

I can't get token in **getToken()** method. I think this is the main issue. How can I solve this?

[TatankaConCube]

Yes, sure, it is the main problem. But I do not understand, which token you used before for creating a subscription?
Which version of flutter_apns plugin do you use? or just from GitHub like in our documentation?

[TatankaConCube]

flutter_apns plugin depends on firebase_messaging plugin, please read its Readme and add needed configs to your project.

[Significantinfotech2020]

@TatankaConCube

Yes, sure, it is the main problem. But I do not understand, which token you used before for creating a subscription?

I use this method for getting token

if (connector.token.value != null) {
    String token = connector.token.value;
    log('Exist token: $token');
  } else {
    connector.token.addListener(() {
      String token = connector.token.value;
      log('Updated token: $token');
    });

I use flutter_apns: ^1.3.1.

[Significantinfotech2020]

Dear @TatankaConCube

I already done all this requirement. I have only one confusion for this this plugin. Should I have to mention below method which is given in firebase_messaging documentation?

firebase_messaging

[TatankaConCube]

I can't get token in getToken() method.

how you created subscriptions before without this method? Whit token you used?

Should I have to mention below method which is given in firebase_messaging documentation?

No, you don't need this method, it is just an example, how to send push notification from the app. Our server does similar logic when you create an event or send a push notification from the ConnectyCube admin panel. But you can use it for testing push notifications on your device without the Connectycube server.

[Significantinfotech2020]

@TatankaConCube

how you created subscriptions before without this method?

I use in all above method in this way. If I made mistake then suggest me.

void onSendChatMessage(String content) async {
    await notificationEnable();
    if (content.trim() != '') {
      final message = createCubeMsg();
      message.body = content.trim();
      await subScription();
      await init();

      sendPushNotification();
      onSendMessage(message);
    } else {
      Fluttertoast.showToast(msg: 'Nothing to send');
    }
  }

Whit token you used?

Now, I get token in init() method.

• In init() method I use token

if (connector.token.value != null) {
      String token = connector.token.value;
      print('Exist token: $token');
    } else {
      connector.token.addListener(() {
        String token = connector.token.value;
        print('Updated token: $token');
      });

• In subscription() method, I use this token

parameters.pushToken = '${_cubeDialog.getRecipientId()}...${_cubeDialog.userId}';

[TatankaConCube]

Try to clear all app data, then completely remove it from the device and install it again. During writing documentation, I did the same step by step and it worked. I can't understand why it does not work for you (((

[TatankaConCube]

parameters.pushToken it is 'key', which FCM uses for identifying your device. It is like 'receiverId' for FCM when the Connectycube server sends push notifications. It should be the only token from the system, but not any random data.

@TatankaConCube
But sir I did not know hoe to get this 'key', I mean 'receiverId'. Actually, I mean where I can get this?

[TatankaConCube]

In our example it is the method getToken(). You can try to use another plugins for getting this data.

I mean this part from our doc

// getting token which used for subscription on Push Notifications on ConnectyCube server

Yes, but in dashboard when I clicked on Push Notification -> Queue tab, notification status, it displays 2 Delivered, 2 Failed and above log.

[TatankaConCube]

Try to remove all subscriptions in the Connectycube dashboard and do the same again (reinstall the app (delete completely and install it again), subscribe, and send push notification). And see logs from callbacks for receiving push notifications on your device, I mean them:

connector.configure(
    onLaunch: onLaunch,
    onMessage: onMessage,
    onResume: onResume,
    onBackgroundMessage: onBackgroundMessage);

I did same step as you suggest, now I get title and body parameter null in onMessage() method.

does it mean you receive a push notification on the device?

FYI, ConnectyCube server sends push notification with type 'data' not 'notification' it means you have search your data in parameter 'data', like in my draft code

[Significantinfotech2020]

does it mean you receive a push notification on the device?

@TatankaConCube

No, I don't receive notification on device but only got above log. Also there is nothing changes in firebase console.

[TatankaConCube]

what means it?

now I get title and body parameter null in onMessage() method

In the log I can't see any errors, it means the Connectycube server successfully sent a push notification to FCM server. Please add logs to all callbacks and try to send push notification again.

[TatankaConCube]

"delivered": true,
"delivered_at": "2020-10-26T11:31:03+00:00",

it means push notification successfully delivered to FCM server

[Significantinfotech2020]

Dear @TatankaConCube

For Firebase connection with connectycube_sdk, I have confusions are that

• Should I have to enable any authentication sign-in option filed like email/password or phone in firebase console?

• While using firebase_messaging packages to configure project, I have to define this two steps in my project or not?

5. Define a TOP-LEVEL or STATIC function to handle background messages

Future<dynamic> myBackgroundMessageHandler(Map<String, dynamic> message) async {
  if (message.containsKey('data')) {
    // Handle data message
    final dynamic data = message['data'];
  }

  if (message.containsKey('notification')) {
    // Handle notification message
    final dynamic notification = message['notification'];
  }

  // Or do other work.
}

Note: the protocol of data and notification are in line with the fields defined by a RemoteMessage.

6. Set onBackgroundMessage handler when calling configure

_firebaseMessaging.configure(
      onMessage: (Map<String, dynamic> message) async {
        print("onMessage: $message");
        _showItemDialog(message);
      },
      onBackgroundMessage: myBackgroundMessageHandler,
      onLaunch: (Map<String, dynamic> message) async {
        print("onLaunch: $message");
        _navigateToItemDetail(message);
      },
      onResume: (Map<String, dynamic> message) async {
        print("onResume: $message");
        _navigateToItemDetail(message);
      },
    );

Note: configure should be called early in the lifecycle of your application so that it can be ready to receive messages as early as possible. See the example app for a demonstration.

Because this two method is same as connectycube_sdk methods. That's why I have this confusion?

Note: the protocol of data and notification are in line with the fields defined by a RemoteMessage.

6. Set onBackgroundMessage handler when calling configure

_firebaseMessaging.configure(
      onMessage: (Map<String, dynamic> message) async {
        print("onMessage: $message");
        _showItemDialog(message);
      },
      onBackgroundMessage: myBackgroundMessageHandler,
      onLaunch: (Map<String, dynamic> message) async {
        print("onLaunch: $message");
        _navigateToItemDetail(message);
      },
      onResume: (Map<String, dynamic> message) async {
        print("onResume: $message");
        _navigateToItemDetail(message);
      },
    );

Note: configure should be called early in the lifecycle of your application so that it can be ready to receive messages as early as possible. See the example app for a demonstration.

Because this two method is same as connectycube_sdk methods. That's why I have this confusion?

@TatankaConCube

Please give me answer asap for my confusion.

[TatankaConCube]

From the Firebase console you need:

• enable Cloud messaging;
• get Server token for Connectycube admin panel;
• download and add to project google-services.json;
  These three points required from Firebase for working with FCM;

I have to define this two steps in my project or not?

yes, you have to create this static method and set it as the listener for the onBackgroundMessage callback.

@TatankaConCube

you have to create this static method and set it as the listener for the onBackgroundMessage callback.

Please help me how and where I have to change in code snippet. I mean in init() method I have to initialize any function?

[TatankaConCube]

you can initialize plugin in method void initState() of your widget where you have logged in user. In this place, you can set listeners for events. The main thing - you have to do this immediately when you got logged in user.

How can I get title and body parameter in onMessage() method while sending push_notification which I get null.

onMessage: {notification: {title: null, body: null}, data: {custom_parameter1: FLUTTER_NOTIFICATION_CLICK, custom_parameter2: custom parameter value 2, message: greyj}}

Please give me suggestion asap.

Please give me suggestion asap.

@TatankaConCube

Please give solution of above question. Please reply!!

[TatankaConCube]

As I said before, the Connectycube server sends push notifications with type 'data', so you can add all required information to 'parameters' during the event creation. You can add all the needed data to this parameter.

One question - did I right understand, now you can receive push notifications on the device?

[Significantinfotech2020]

@TatankaConCube

• This data I use for creating event. In this I mention all of the data which required as per documentation. Please check below code and if made mistake then please suggest me.

void sendPushNotification() {
    CreateEventParams params = CreateEventParams();
    params.parameters = {
      'message': '${textEditingController.text}',
      'custom_parameter1': 'custom parameter value 1',
      'custom_parameter2': "custom parameter value 2",
      'ios_voip': 1
    };
    params.notificationType = '${NotificationType.PUSH}';
    params.environment = CubeEnvironment.DEVELOPMENT;
    params.usersIds = _cubeDialog.occupantsIds;

    createEvent(params.getEventForRequest()).then((cubeEvent) {
      print('CUBE EVENT -----> $cubeEvent');
    }).catchError((error) {
      print('CUBE EVENT ERROR -----> $error');
    });
  }

One question - did I right understand, now you can receive push notifications on the device?

I can receive notification, if I get onMessage() method in 'data' parameter rather than 'notification'. Sorry, still I did not receive notification on device. But It successfully generated from connectycube dashboard.

onMessage: {notification: {title: null, body: null}, data: {custom_parameter1: FLUTTER_NOTIFICATION_CLICK, custom_parameter2: custom parameter value 2, message: greyj}}

@TatankaConCube
In above code snippet where I have to pass type 'data' as you said? Please suggest me.

[TatankaConCube]

it can be like:

params.parameters = {
      'message': '${textEditingController.text}',
      'title': someTitle,
      'body': someBody,
// all needed parameters here 
      'ios_voip': 1
    };

[Significantinfotech2020]

it can be like:

params.parameters = {
      'message': '${textEditingController.text}',
      'title': someTitle,
      'body': someBody,
// all needed parameters here 
      'ios_voip': 1
    };

@TatankaConCube

I did exact same as you suggest but still I face that title and parameter null in onMessage() method. What should I do now?

params.parameters = {
'message': '${textEditingController.text}',
'title': 'Chat Notification',
'body': "chat body",
'notification_type': 'push',
'push_type': 'gcm',
'environment': 'development',
'ios_voip': 1,
'usersIds' = ${_cubeDialog.occupantsIds}
};

[TatankaConCube]

in the 'data' field? are you sure?
please provide log, like you did before. I mean it:

onMessage: {notification: {title: null, body: null}, data: {custom_parameter1: FLUTTER_NOTIFICATION_CLICK, custom_parameter2: custom parameter value 2, message: greyj}}

[Significantinfotech2020]

@TatankaConCube

Yes.

please provide log, like you did before. I mean it:

onMessage, message: {notification: {title: null, body: null}, data: {notification_type: push, push_type: gcm, environment: development, body: c
hat body, title: Chat Notification, message: gfghgg}}

[TatankaConCube]

what about it:

data: {notification_type: push, push_type: gcm, environment: development, body: chat body, title: Chat Notification, message: gfghgg}

why you say

title and parameter null in onMessage()

I'm confused...

sorry for this.
but still I didn't receive notification.

[TatankaConCube]

do you mean notification in the Android notifications center? For the Android platform, you should do it by yourself, please read our documentation (at the end of the section). For iOS, it is a system feature and here you can manage only actions, which happen by clicking on the notification.

[Significantinfotech2020]

@shivanijha002

Notification: title and body should not be null. How can I set these values?

For the Android platform, you have to set them to the parameters map, for iOS you can use some additional parameter from our API. Note: ConnectyCube server always sends GCM with 'data' type, not 'notification'.

Also, I do not get any notification on device. Though message is getting captured in debug console.

For Android, it is expected behavior. You have to do it yourself. For example, you can use flutter_local_notifications plugin for it.
For iOS, it is a system feature and the system does it instead of you.

Thank you for the details. It might be useful if you can add it in your documentation. I wasted 2 days trying out different things and hoping it will work without anything external.
flutter_local_notifications has worked for me on Android.

Hello @shivanijha002

I face same issue as you mentioned above. Please suggest me how can I use flutter_local_notifications with firebase_messaging for Android device notification. Please suggest me asap.

[TatankaConCube]

@Significantinfotech2020 in your callback onMessage you have all the needed data, please read documentation how to configure notification with this data and how to show it.

[Significantinfotech2020]

Hello @TatankaConCube,

I share my chat_dialog_screen.dart file. In this file I implemented flutter_local_notifications with firebase_messaging, but still I can't get any notification on receiver device. In this code I got notification on sender device with only notification title.
So, please check my code and let me know where I made mistake? What changes I have to do in this code?

[TatankaConCube]

There are few plugins for listening push notifications and a lot of code is commented. Do you receive a push event in your callbacks?
We are going to plan to add a push notification feature for the Chat sample in the next iteration.

[TatankaConCube]

@Significantinfotech2020 today I pushed draft code for enabling push notifications in the Chat sample. The main logic for subscription, listening push notifications and showing local notifications placed in push_notifications_manager.dart

At current moment works (tested on iOS and Android):

• subscription on push notifications;
• receiving push notifications in the background (or killed) and foreground;
• displaying notifications in Notification Center;
• unsubscription from push notifications after logout from the app;

Note: it is just a draft and not all features implemented yet, for example, navigation to concrete chat by notification click, etc.

@TatankaConCube I checked this code. It's working as you describe. Thanks 👍

[Significantinfotech2020]

Hello @TatankaConCube
In your code sometimes I got notification but sometimes not. I had updated code as per latest documentation. There was not any error in the terminal.

[TatankaConCube]

In which way do you send push notification? From admin panel?

[Significantinfotech2020]

@TatankaConCube

In which way do you send push notification?

I am sending notification as per your updated code.

From admin panel?

No.

[TatankaConCube]

Did these notifications present in the queue in the Admin panel?

[Significantinfotech2020]

Did these notifications present in the queue in the Admin panel?

when I receive notification on device that entries were in admin panel, but when I not get notification, that entry was not in queue.

[TatankaConCube]

it means you have a problem not with receiving but with sending notifications, investigate this part of your code

[Significantinfotech2020]

@TatankaConCube In below method 6543 is what? Is this application ID or Account ID or anything else?

FlutterLocalNotificationsPlugin().show(
    6543, 
    "Chat sample",
    data['message'].toString(),
    platformChannelSpecifics,
    payload: 'item x',
  );

[TatankaConCube]

There is code not from our SDK, it is a code of flutter_local_notifications plugin. There is the description for this code example. In my example, 6543 is just a random notification id. Notification id - for the Android system it is the unique id of your notification, by this id you can cancel notification, update it, etc.

[TatankaConCube]

Implemented in the latest version. Closing...
