Platform Specific Extra Steps #
Following extra steps after the installation of the dengage_flutter SDK are required for it to work properly.

iOS Specific Extra steps
Requirements

D·engage Integration Key
iOS Push Cerificate
iOS Device (you need to test on a real device for notifications)
A mac with latest Xcode

Steps #
1. Endpoint Configuration in PInfo.list
For initial setup, if you have given URL addresses by D·engage Support team, you need to setup url address by using Info.plist file. Otherwise you don’t need to add anything to Info.plist file. Following screenshot for the keys in Info.plist file.


Note: Please see API Endpoints by Datacenter documentation in this section for end points. here is link

2. Add Required Capabilities
In Xcode, select the root project and main app target. In Signing & Capabilities, select All and + Capability. Add "Push Notifications" and Background Modes. Kindly make sure to tick Remote Notifications in Background Modes.

screenshot 2

3. Add Notification Service Extension (required only if using rich notifications)
The DengageNotificationServiceExtension allows your application to receive rich notifications with images and/or buttons, and to report analytics about which notifications users receive.
3.1 In Xcode Select File > New > Target
3.2 Select Notification Service Extension then press Next

3.3 Enter the product name as DengageNotificationServiceExtension and press Finish.

Do NOT press "Activate" on the dialog shown after this.


3.4 Press Cancel on the Activate scheme prompt.


By canceling, you are keeping Xcode debugging your app, instead of just the extension. If you activate by accident, you can always switch back to debug your app within Xcode (next to the play button).

3.5 In the Project Navigator, select the top-level project directory and select the DengageNotificationServiceExtension target in the project and targets list. Ensure the Deployment Target is set to iOS 10 for maximum platform compatibility.

3.6 Finish Notification Service Extension Setup
If you did not use Cocoapods, follow these steps.

Note: non-cocoapods steps yet to be determined.

Otherwise, continue with the following setup:

In your Project Root > iOS > Podfile, add the notification service extension outside the main target (should be at the same level as your main target):

target 'DengageNotificationServiceExtension' do
pod 'Dengage.Framework',‘~> 3.0.6’
end
copied to clipboard
Close Xcode. While still in the ios directory, run pod install again.

Open the .xcworkspace file in Xcode. In the DengageNotificationServiceExtension directory > NotificationService.swift file, replace the whole file contents with the code below:

override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
self.contentHandler = contentHandler
bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent)

if let bestAttemptContent = bestAttemptContent {

// add this line of code
Dengage.didReceiveNotificationExtentionRequest(receivedRequest: request, with: bestAttemptContent)
contentHandler(bestAttemptContent)
}
}
copied to clipboard

Ignore any build errors at this point, we will resolve these later by importing the D·engage library.


4. Setup Dengage SDK (it include two steps of the iOS native SDK. 1. Setting Integration Key 2. Initialization with Launch Options) #
Integration Key is genereted by CDMP Platform while defining application. It is a hash string which contains information about application.
At the beginning of your application cycle you must set Integration Key and right after initialize sdk with launch options.
Following sample shows how to do that in your AppDelegate.swift file:
Sample:
In the AppDelegate.swift
import UIKit
import Flutter
import dengage_flutter // ADD THIS IN IMPORTS

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
GeneratedPluginRegistrant.register(with: self)
/************* FLutter Setup Code Starts here ********************/
// please Node key here is the integeration Key received while registering your iOS Application on Dengage Dashboard.
let coordinator = DengageCoordinator.staticInstance;
coordinator.setupDengage(key: "K8sbLq1mShD52Hu2ZoHyb3tvDE_s_l_h99xFTF60WiNPdHhJtvmOqekutthtzRIPiMTbAa3y_p_l_PZqpon8nanH8YnJ8yYKocDb4GCAp7kOsi5qv7mDR_p_l_qOFLLp9_p_l_lloC6ds97X", launchOptions: launchOptions as NSDictionary?);
/************* FLutter Setup Code Ends here ********************/
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}

override func application( _ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let coordinator = DengageCoordinator.staticInstance;
coordinator.registerForPushToken(deviceToken:deviceToken)
}
}

copied to clipboard
5. Register for remote notification with device token #
To register for remote notifications with device token, add following method and code inside your AppDelegate.swift file:
import UIKit
import Flutter
import dengage_flutter // ADD THIS IN IMPORTS

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
// ... other things here ...

/**************** Here this method override *****************/
override func application( _ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let coordinator = DengageCoordinator.staticInstance;
coordinator.registerForPushToken(deviceToken:deviceToken)
}
}

Create DengageManager instance #
First, you need to create DengageManager instance in your main or launcher activity.
// import statement
import com.example.dengage_flutter.DengageCoordinator;

// ...
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Following line need to be added
DengageCoordinator.sharedInstance.setupDengage(
true,
"FEYl27JxJfay6TxiYCdlkP2FXeuhNfEoI8WkxI_p_l__s_l_5sLbzKmc9c88mSZxRCrLuqMK4y0e8nHajQnBt8poBNDMvNtIytYKZ6byBQZOE8kqkkgDnlye2Lb5AcW3tuIWQjYz",
"your-huawei-key-here",
applicationContext
)
}
copied to clipboard
After these steps, You will be able to send a push notification message to your app.
Change Subscription Api Endpoint #
You can change subscription api endpoint by adding following metadata tag in YourProject/android/src/main/AndroidManifest.xml
// for prod
<meta-data
android:name="den_push_api_url"
android:value="https://push.dengage.com" />

// for dev
<!-- android:value="https://pushdev.dengage.com" />-->
copied to clipboard
Note: Please see API Endpoints By Datacenter to set your subscription end point.
Changing Event Api Endpoint #
similar to subscription endpoints, you can change event api endpoints by setting following metadata tag in YourProject/android/src/main/AndroidManifest.xml
// for prod
<meta-data
android:name="den_event_api_url"
android:value="https://event.dengage.com" />

// for dev
<!-- android:value="https://eventdev.dengage.com" />-->
copied to clipboard
Note: Please see API Endpoints By Datacenter to set your event end point.
Now you can setContactKey like mentioned here

Supported Versions #

iOS
D·engage Mobile SDK for IOS supports version IOS 10 and later.


android
D·engage Mobile SDK for Android supports version 4.4 (API Level 19) and later.
Huawei
D·engage Mobile SDK for Huawei supports all new versions.

Usage #
Subscription #
Subscription is a process which is triggered by sending subscription event to D·engage. It contains necessary informations about application to send push notifications to clients.
Subscriptions are self managed by D·engage SDK and subcription cycle starts with Prompting user permission. SDK will automaticlly send subscription events under following circumstances:

Initialization
Setting Contact key
Setting Token
Setting User Permission (if you have manual management of permission)

Asking User Permission for Notification #

Note: Android doesn't require to ask for push notifications explicitly. Therefore, you can only ask for push notification's permissions on iOS.

IOS uses shared UNUserNotificationCenter by itself while asking user to send notification. D·engage SDK manager uses UNUserNotificationCenter to ask permission as well. Apple Doc Reference
If in your application, you want to get UserNotification permissions explicitly, you can do by calling one of the following methods:
// At the top import
import 'package:dengage_flutter/dengage_flutter.dart';

// somewhere in your javascript/typescript code
DengageFlutter.promptForPushNotifications()
copied to clipboard
OR
// At the top import
import 'package:dengage_flutter/dengage_flutter.dart';

// somewhere in your javascript/typescript code
Object result = await DengageFlutter.promptForPushNotificationsWitCallback()
copied to clipboard
Setting Contact Key #
Contact Key represents user id in your system. There are two types of devices. Anonymous Devices and Contact Devices. Contact Devices contains Contact Key.
To track devices by their contacts you need to set contact key on SDK.

Note: It is recommended to call this method, if you have user information. You should call in every app open and on login, logout pages.

// import statement
import 'package:dengage_flutter/dengage_flutter.dart';

// in js/ts code
Object result = await DengageFlutter.setContactKey(userId: String)


// You may need getting current contact key from SDK. In that case you can use getContactKey
Object result = await DengageFlutter.getContactKey()
copied to clipboard
Manual Management of Tokens #
If you need to get current token or if you are managing token subscription process manually, you can use setToken and getToken functions.
// At the top import
import 'package:dengage_flutter/dengage_flutter.dart';

// somewhere in your javascript/typescript code
Object result = await DengageFlutter.getToken()

// setting the token that is taken manually
DengageFlutter.setToken(token)
copied to clipboard
User Permission Management (optional) #
If you manage your own user permission states on your application you may send user permission by using setUserPermission method.
// At the top import
import 'package:dengage_flutter/dengage_flutter.dart';

// somewhere in your javascript/typescript code
DengageFlutter.setUserPermission(true)

// For getting last permission set by user
Object result = await DengageFlutter.getUserPermission(true)
copied to clipboard
Logging #
SDK can provide logs for debuging. It displays queries and payloads which are sent to REST API’s.
To validate your inputs you can enable SDK’s log by a method.
// isVisible is Boolean. By default isVisible set to false.
DengageFlutter.setLogStatus(isVisible)
copied to clipboard
Handling Notification Action using onNotificationClicked event #
SDK provides a listener if you want to get and parse payload manually, whenever a push notification is clicked.
// declare as class level static variable
static const EventChannel eventChannel = EventChannel("com.dengage.flutter/onNotificationClicked");

@override
void initState() {
// rest of code here ...

eventChannel.receiveBroadcastStream().listen(_onEvent, onError: _onError);

super.initState();
}

void _onEvent(Object event) {
print("in on Event object is: ");
print(event);
}

void _onError(Object error) {
print("in on Error Object is: ");
print(error);
}

DeepLinking #
SDK supports URL schema deeplink. If target url has a valid link, it will redirect to the related link.
Please see related links below about deeplinking.

iOS Specific Links
Apple Url Scheme Links
Apple Universal Link


android Specific Links
Create a deep link for a destination
Create Deep Links to App Content

Rich Notifications #
Rich Notifications is a notification type which supports image, gif, video content. D·engage SDK supports varieties of contents and handles notification.
Rich Notifications supports following media types:

Image
Video
Gif

For further details about rich notification and its setup on iOS side please follow this link

Note: on Android there is no special setup required for rich notifications.

Carousel Push #
Carousel Push is a notification type which has a different UI than Rich Notification. SDK will handle notification payload and displays UI if it’s a carousel push. Carousel Push functionality allows you to show your notification with a slideshow.

iOS
Requirements #

iOS 10 or higher
Notification Service Extension
Notification Content Extension
Dengage.Framework.Extensions

to setup Carousel Push on iOS you can follow this link


android
Requirements #

Android SDK 2.0.0+

to setup Carousel Push on android you can follow this link

Action Buttons #
Android SDK allows you to put clickable buttons under the notification. Action buttons are supported in Android SDK 2.0.0+.
For further setup of Action Buttons, follow this link.
Event Collection #
In order to collect android mobile events and use that data to create behavioral segments in D·engage you have to determine the type of events and data that needs to collected. Once you have determined that, you will need to create a “Big Data” table in D·engage. Collected events will be stored in this table. Multiple tables can be defined depending on your specific need.
Any type of event can be collected. The content and the structure of the events are completely flexible and can be changed according to unique business requirements. You will just need to define a table for events.
Once defined, all you have to do is to send the event data to these tables. D·engage SDK has only two functions for sending events: sendDeviceEvent and sendCustomEvent. Most of the time you will just need the sendDeviceEvent function.
1. Login / Logout Action #
If the user loggs in or you have user information, this means you have contact_key for that user. You can set contact_key in order to match user with the browser. There are two functions for getting and setting contact_key.
1.a setContactKey #
If user logged in set user id. This is important for identifying your users. You can put this function call in every page. It will not send unnecessary events.
code example is here
1.b getContactKey #
to get the current user information from SDK getContactKey method can be used.
// in imports
import 'package:dengage_flutter/dengage_flutter.dart';

// in the code, where user information required
Object result = await DengageFlutter.getContactKey()
copied to clipboard
2. Event Collection #
If your D·engage account is an ecommerce account, you should use standard ecommerce events in the SDK. If you need some custom events or your account is not standard ecommerce account, you should use custom event functions.
2.1 Events for Ecommerce Accounts #
There are standard ecommerce events in D·engage SDK.

Shopping Cart Events #
These events will be stored in shopping_cart_events and shopping_cart_events_detail. There are 4 shopping cart event functions. addToCart, removeFromCart, viewCart, beginCheckout Every shopping cart event function needs all items in cart as an array. You must send last version of the shopping cart.
For example: If there is one item in cart and item id is 5. And after that, an add to cart action is happened with the item id 10. You have to send 10 as product_id in event parameters and you must send current version of cart items. Meaning [5, 10]
// import statement
import 'package:dengage_flutter/dengage_flutter.dart';

// All items currently exists in shopping cart must be added to an array
const cartItem = {}, // cartItem will be an object with key:value types as String:Any

cartItem["product_id"] = 1
cartItem["product_variant_id"] = 1
cartItem["quantity"] = 1
cartItem["unit_price"] = 10.00
cartItem["discounted_price"] = 9.99
// ... extra columns in shopping_cart_events_detail table, can be added in cartItem

Wishlist Event #
These events will be stored in wishlist_events and wishlist_events_detail.
There are 2 wishlist event functions. addToWishlist, removeFromWishlist. In every event call, you can send all items in wishlist. It makes it easy to track current items in wishlist.
// import statement
import 'package:dengage_flutter/dengage_flutter.dart';

// Current items in wishlist
const wishListItem = {}
wishListItem["product_id"] = 1

const wishListItems = []
wishListItems.push(wishListItem)


// Add to wishlist action
const params = [
"product_id": 1,
// ... extra columns in wishlist_events table, can be added here
"items": wishlistItems // current items
]
DengageFlutter.addToWishList(params)

// Remove from wishlist action

Search Event #
Search events will be stored in search_events table.
const params = {
"keywords":"some product name", // text in the searchbox
"result_count":12,
"filters":"" //you can send extra filters selected by user here. Formating is not specified
// ... extra columns in search_events table, can be added here
}
DengageFlutter.search(params)
copied to clipboard
2.1 Custom Events #
Send device specific events
You can use sendDeviceEvent function for sending events for the device. Events are sent to a big data table defined in your D·engage account. That table must have relation to the master_device table. If you set contact_key for that device. Collected events will be associated for that user.
// for example if you have a table named "events"
// and events table has "key", "event_date", "event_name", "product_id" columns
// you just have to send the columns except "key" and "event_date", because those columns sent by the SDK
// methodSignature => dengage(‘sendDeviceEvent’, tableName: String, dataObject, callback);
Map data = new HashMap<String, dynamic>();
data["name"] = "Kamran Younis";
await DengageFlutter.sendDeviceEvent("tableName", data);

App Inbox #
App Inbox is a screen within a mobile app that stores persistent messages. It’s kind of like an email inbox, but it lives inside the app itself. App Inbox differs from other mobile channels such as push notifications or in-app messages. For both push and in-app messages, they’re gone once you open them.
In other words, D·engage admin panel lets you keep selected messages on the platform and Mobile SDK may retreive and display these messages when needed.
In order to save messages into App Inbox, you need to select “Save to Inbox” option when sending messages in D·engage admin panel by assigning an expire date to it.
Inbox messages are kept in the memory storage of the phone until app is completely closed or for a while and D·engage SDK provides functions for getting and managing these messages.
Requirements

Android: D·engage SDK 3.2.3+
iOS: D·engage SDK 2.5.21+

Methods
There are 3 methods to manage App Inbox Messages


To get app inbox messages from the server
Map<String, dynamic> result = await DengageFlutter.getInboxMessages(offset, limit).catch(err => err)
// where offset: Int, limit: Int = 20
// inboxMessages now either have array of Inbox messages or an error.
copied to clipboard


To delete a specific message from the inbox.
Object result = await DengageFlutter.deleteInboxMessage(id).catch(err => err)
// where id: String
// delMsgResponse now either have {success: true, id: "id-of-msg-deleted"} or an error
copied to clipboard


to mark a specific message as clicked.
Object result = await DengageFlutter.setInboxMessageAsClicked(id).catch(err => err)
// where id: String &
// msgSetAsClicked now either have {success: true, id: "id-of-msg-deleted"} or an error
copied to clipboard


In-App Messaging #
In-app message is a type of mobile message where the notification is displayed within the app. It is not sent in a specific time but it is show to user when user are using the app. Examples include popups, yes/no prompts, banners, and more. In order to show in-app messages, there is no permission requirement.
Requirements

iOS: D·engage SDK 3.2.3+
android: D·engage SDK 3.2.3+

Methods
Created messages will be stored in D·engage backend and will be served to mobile SDKs. If you integrated mobile SDK correctly for push messages, for using in-app features you just have to add setNavigtion function to every page navigation.
If you want to use screen name filter, you should send screen name to setNavigation function in every page navigation.
Simple In App Messaging
DengageFlutter.setNavigation()
copied to clipboard
In App Messaging with Screen Name
DengageFlutter.setNavigation('cart')
copied to clipboard
In App Messaging with Screen Name and Page Data
//
// (Coming soon)
// Scheduled: April 2021
// if you have extra information
// you can send them to use screen data filters.
Object screenData = {productId: "~hs7674", price: 1200}
DengageFlutter.setNavigation('product', screenData)
