Push notification

When your app becomes disconnected from Stringee server, you can not receive real-time updates. In this case, you use Stringee Push Notification to keep your app's data updated.

Check Flutter Push Notification to create an flutter push project on Stringee dashboard and generate APNs Auth Key for push notification.

Stringee use Remote Push Notification to send push to devices for chat. So, you need to do the following steps:

1. Get token for remote push notification.

In Flutter, you can use any library to get APNS device token for push. For example, if you are using FlutterFire, you can call the following function to get that token:

String? pushToken = '';
if (Platform.isAndroid) {
    pushToken = await FirebaseMessaging.instance.getToken();
} else {
    pushToken = await FirebaseMessaging.instance.getAPNSToken();
}

2. Register token with Stringee server

Send your device token to Stringee server as follow:

_stringeeClient.registerPush(pushToken!, isProduction: false, isVoip: false).then((result) {
    debugPrint('registerPush: message - ${result['message']}');
});

Note:

For ios:

• This token is not for voip push, so you need to pass isVoip = false. Its different compare to register voip token for call.
• isProduction value depend on your environment, isProduction = true (production) / false (development).

If everything is success, you will receive remote push notifications for chat. Stringee push notification data has the following format:

{
    data = {
        map = {
            data = {
                map = {
                    avatarUrl = "";
                    convId = "conv-vn-1-OZQMBPBUWM-1553965638358";
                    convName = Demo;
                    createdTime = 1554261740264;
                    displayName = hoangnam;
                    from = user1;
                    isGroup = 0;
                    message = {
                        map = {
                            content = Alo;
                            metadata = {
                                map = {};
                            };
                        };

                    };
                    msgId = "msg-vn-1-OZQMBPBUWM-1553965654245";
                    seq = 2;
                    type = 1;
                };
            };
            stringeePushNotification = "1.0";
            type = "CHAT_EVENT";
        };
    };
}
