Push notification implementation in Flutter Parse SDK?

[guilhermedaldim]

Is it possible with the Flutter Parse SDK to send push notification?

Send a notification to a specific user with deviceToken and be able to handle it according to the notification payload?

In advance, thank you.

I use firebase admin on the server side and then use cloud code to send a notification

I can send and receive notifications with firebase admin, thanks @pastordee.

However, on android, when I get notifications in the foreground, the application crashes.

How did you set up your client application?

` void configNotification() {
print("onMessage: Initialization ");
var android = new AndroidInitializationSettings('@drawable/ic_notifications');
var ios = new IOSInitializationSettings();
var platform = new InitializationSettings(android, ios);
flutterLocalNotificationsPlugin.initialize(platform);
// _firebaseMessaging.subscribeToTopic('all');

_firebaseMessaging.getToken().then((String token) {
    assert(token != null);
    updateParseInstallation(token);
  });

 _firebaseMessaging.requestNotificationPermissions(
    const IosNotificationSettings(sound: true, badge: true, alert: true)
  );
_firebaseMessaging.onIosSettingsRegistered.listen((IosNotificationSettings settings) {
    print("Settings registered: $settings");
  });



_firebaseMessaging.configure(
  onMessage: (Map<String, dynamic> message) async {
    print("onMessage: $message");
    onMessageNotificationsAlert(message);
    
  },
  onLaunch: (Map<String, dynamic> message) async {
    print("onLaunch: $message");
    onLaunchNotificationsAlert(message); 
  },
  onResume: (Map<String, dynamic> message) async {
    print("onResume: $message");
    onResumeNotificationsAlert(message);
  },
);

}
`

e.g
`onMessageNotificationsAlert(Map<String, dynamic> message) async{
print("onMessageNotificationsAlert");

    Map notification = message['notification'];
    var body = notification['body'];
    var title = notification['title'];
    var view = notification['view'];
    var objectId = notification['objectId'];

}`

Thanks pastordee, how did you integrate firebase admin with parse server users?

It would be very useful for everyone to have a solution to send push notifications easily from the parse server.

[RodrigoSMarques]

Hi @pamarcan
I am using OneSignal.
I associate the OneSignal user with the user's ObjectID on the Parse Server.
Using Cloud Code I send Push by activating the OneSignal API.

1. npm firebase admin

2. in my main.js in the cloud folder
   var admin = require("firebase-admin"); var serviceAccount = require("/path-to-/serviceAccountKey.json"); admin.initializeApp({ credential: admin.credential.cert(serviceAccount), databaseURL: "https://***********.firebaseio.com" });

               `
                  var options = {
    		priority: "high",
    		timeToLive: 60 * 60 * 24
    	};
    	var payloadIOS ={
    		
    		notification: {
    			title: title,
    			body: theMessage,
    			view: "woeGroup",
    			objectId: post.id
    		}
    		
    	};
    	var payloadAndroid ={
    		
    		notification: {
    			title: title,
    			body: theMessage,
    			view: "woeGroup",
    			objectId: post.id
    		}
    		
    	};
   

`

       `
        var pushQueryFCM = new Parse.Query(Parse.Installation);
    pushQueryFCM.notEqualTo('userId', user.id);// the user posting is not in the channels
    pushQueryFCM.equalTo('channels', publicId);
        pushQueryFCM.find({useMasterKey:true})
		.then((pushQuery) => {
			
			for (i = 0; i < pushQuery.length; i++) {
				
				var deviceType =  pushQuery[i].get('deviceType');
				var token = pushQuery[i].get('deviceToken');
				
				if(deviceType == "ios" && token != ""){
					
					admin.messaging().sendToDevice(token, payloadIOS,options)
					.then(function(response){
						console.log("messaging=>**********successfully" + response);
					})
					.catch(function(error){
						console.log("messaging=>********** Got an error " + error.code + " : " + error.message);
					});
					
					
				}else if(deviceType == "android" && token != ""){
					
					admin.messaging().sendToDevice(token, payloadAndroid,options)
					.then(function(response){
						console.log("messaging=>**********successfully" + response);
					})
					.catch(function(error){
						console.log("messaging=>********** Got an error " + error.code + " : " + error.message);
					});


					
				}//
				
								
			}
		})
		.catch(function(error){
			console.log("messaging=>********** Got an error  pushQueryFCM " + error.code + " : " + error.message);
		});

`

3. In your pubspec.yaml
   firebase_messaging
   flutter_local_notifications

4. main.dart
   FirebaseMessaging _firebaseMessaging = FirebaseMessaging();
   FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin;

   `
   void configNotification() {
   print("onMessage: Initialization ");
   var android = new AndroidInitializationSettings('@drawable/ic_notifications');
   var ios = new IOSInitializationSettings();
   var platform = new InitializationSettings(android, ios);
   flutterLocalNotificationsPlugin.initialize(platform);

   _firebaseMessaging.getToken().then((String token) {
   assert(token != null);
   updateParseInstallation(token);
   });

   _firebaseMessaging.requestNotificationPermissions(
   const IosNotificationSettings(sound: true, badge: true, alert: true)
   );
   _firebaseMessaging.onIosSettingsRegistered.listen((IosNotificationSettings settings) {
   print("Settings registered: $settings");
   });

   _firebaseMessaging.configure(
   onMessage: (Map<String, dynamic> message) async {
   print("onMessageNotificationsAlert $message");
   onMessageNotificationsAlert(message);

   },
   onLaunch: (Map<String, dynamic> message) async {
   onLaunchNotificationsAlert(message);
   },
   onResume: (Map<String, dynamic> message) async {
   onResumeNotificationsAlert(message);
   },
   );

}

Future updateParseInstallation(token) async{

print("updateParseInstallationt $token");
var installation = await ParseInstallation.currentInstallation();
installation.set("deviceToken", token);
var apiResponse = await installation.save();
if(apiResponse.success){
print("updateParseInstallationt initInstallation updated ${apiResponse.result}");
}
}

Wow! thanks a lot pastordee

I don't think local messaging is needed, only in case you want to show user a notification if app is opened and in foreground.
Firebase messaging does not display notification if app is opened and in foreground.

Firebase messaging does not display notification if app is opened and in foreground.

Because firebase doesn’t display notification in app that’s why you need something like Flushbar so you can use that to show the in app message yourself

[GursheeshSingh]

Firebase does show notifications.

As explained in their official documentation-
https://pub.dev/packages/firebase_messaging#receiving-messages

If app is in foreground, it doesn't show notifications.

Hello @phillwiggins @RodrigoSMarques @RodrigoSMarques @guilhermedaldim @pamarcan

Is there any updates related to push notifications with parse sdk in flutter?

Can we implement push notifications using parse server sdk for flutter as well?

Waiting for reply.

Thanks.

[RodrigoSMarques]

@MungaraJay
To use the native functionality it is necessary to use Platform Channel and I do not see the need.
Use Firebase Cloud Messaging that has the plugin ready and does the same.
Retrieve the Token from the device with FCM, save the token in Class Installation.
Send Push Notification through Parse and receive it on the device through FCM.

@RodrigoSMarques
Basically EU companies can't send anything at all to USA..so for push notifications I'd have to avoid FCM altogether.
I'm in the middle of moving away from Firebase as GDPR is very restrictive about UE data sent abroad.
I see you're using OneSignal, are you UE based?
Parse seems to offer all I'm currently using for my app and I can host a Parse server on UE Server providers..

Thanks.

@vinnytwice
As far as I know, OneSignal uses FCM in the background. But I might be wrong.
