• Add google-services.json file to your application’s app directory.

• If your app supports HMS add agconnect-services.json file to your application’s app directory.

iOS

• Change the ios platform version to 11.0 or higher in Podfile

platform :ios, '11.0'

• In your project directory, open the file ios/Runner.xcworkspace with Xcode.

• Enable Push Notifications and Background Modes->Remote Notifications capabilities.

• In Xcode, add a new Notification Service Extension target and name it NotificationService. NotificationServiceExtension allows your iOS application to receive rich notifications with images, videos, and badges. It's also required for Related Digital's analytics features and to store and access notification payloads of the last 30 days.

• In your podfile, add below section and then run pod install.

target 'NotificationService' do
	use_frameworks!
	pod 'Euromsg'
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |config|
		config.build_settings['APPLICATION_EXTENSION_API_ONLY'] = 'No'
	end
  end
end

• Set NotificationService target's deployment target to iOS 11.

• Replace NotificationService.swift file content with the code below.

import UserNotifications
import Euromsg

class NotificationService: UNNotificationServiceExtension {

    var contentHandler: ((UNNotificationContent) -> Void)?
    var bestAttemptContent: UNMutableNotificationContent?

    override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
        self.contentHandler = contentHandler
        bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent)
        Euromsg.configure(appAlias: "ios-app-alias", enableLog: true)
        Euromsg.didReceive(bestAttemptContent, withContentHandler: contentHandler)
    }

    override func serviceExtensionTimeWillExpire() {
        guard let contentHandler = self.contentHandler else {
            return;
        }
        guard let bestAttemptContent = self.bestAttemptContent else {
            return;
        }
        contentHandler(bestAttemptContent)
    }
}

• Enable App Groups Capability for your targets. App Groups allow your app to execute code when a notification is recieved, even if your app is not active. This is required for Related Digital's analytics features and to store and access notification payloads of the last 30 days.

  • In your Main App Target go to Signing & Capabilities > All.
  • Click + Capability if you do not have App Groups in your app yet.
  • Select App Groups.
  • Under App Groups click the + button.
  • Set the App Groups container to be group.BUNDLE_ID.relateddigital where BUNDLE_ID is the same as set in Bundle Identifier.
  • Press OK.
  • In the NotificationServiceExtension Target
  • Go to Signing & Capabilities > All
  • Click + Capability if you do not have App Groups in your app yet.
  • Select App Groups
  • In the NotificationContentExtension Target go to Signing & Capabilities > All`.
  • Click + Capability.
  • Select App Groups
  • Under App Groups click the + button.
  • Set the App Groups container to be group.BUNDLE_ID.relateddigital where BUNDLE_ID is the same as your Main App Target Bundle Identifier. Do Not Include NotificationServiceExtension and NotificationContentExtension.
  • Press OK

• If you want to use AdvertisingTrackingID with isIDFAEnabled parameter (see Usage below), you need to add this key to your Info.plist file for iOS 14 and above.

<key>NSUserTrackingUsageDescription</key>
<string>We use advertising identifier!</string>

Usage

Initializing

Import the library

import 'package:relateddigital_flutter/relateddigital_flutter.dart';
import 'package:relateddigital_flutter/request_models.dart';
import 'package:relateddigital_flutter/response_models.dart';

Initialize the library

final RelateddigitalFlutter relatedDigitalPlugin = RelateddigitalFlutter();

@override
void initState() {
  super.initState();
  initLib();
}

Future<void> initLib() async {
  var initRequest = RDInitRequestModel(
    appAlias: Platform.isIOS ? 'ios-app-alias' : 'android-app-alias',
    huaweiAppAlias: 'huawei-app-alias', // pass empty String if your app does not support HMS
    androidPushIntent: 'com.test.MainActivity', // Android only
    organizationId: 'ORG_ID',
    siteId: 'SITE_ID',
    dataSource: 'DATA_SOURCE',
    maxGeofenceCount: 20,  // iOS only
    geofenceEnabled: true,
    inAppNotificationsEnabled: true,
    logEnabled: true,
    isIDFAEnabled: true,  // iOS only
  );

  await relatedDigitalPlugin.init(initRequest, _readNotificationCallback);
}

void _readNotificationCallback(dynamic result) {
  print(result);
}

Push Notifications

Requesting Permission & Retrieving Token

Add the lines below to request push notification permission and retrieve token.

IOS

• Instead of having to prompt the user for permission to send them push notifications, your app can request provisional authorization. In order to enable provisional authorization, you should set isProvisional parameter of requestPermission method to true.

String token = '-';

void _getTokenCallback(RDTokenResponseModel result) {
  if(result != null && result.deviceToken != null && result.deviceToken.isNotEmpty) {
    setState(() {
      token = result.deviceToken;
    });
  }
  else {
    setState(() {
      token = 'Token not retrieved';
    });
  }
}

Future<void> requestPermission() async {
  await relatedDigitalPlugin.requestPermission(_getTokenCallback, isProvisional: true);
}

Carousel Push Notifications

To be able to receive push notifications with carousel, follow the steps below.

IOS

• In Xcode, add a new Notification Content Extension target and name it NotificationContent.
• In your podfile, add below section and then run pod install.

target 'NotificationContent' do
	use_frameworks!
	pod 'Euromsg'
end

• Set NotificationContent target's deployment target to iOS 11.
• Delete MainInterface.storyboard and NotificationContent.swift files. Then create a swift file named EMNotificationViewController.swift under the NotificationContent folder.
• Replace EMNotificationViewController.swift file content with the code below.

import UIKit
import UserNotifications
import UserNotificationsUI
import Euromsg

@objc(EMNotificationViewController)
class EMNotificationViewController: UIViewController, UNNotificationContentExtension {
    
    let carouselView = EMNotificationCarousel.initView()
    var completion: ((_ url: URL?, _ bestAttemptContent: UNMutableNotificationContent?) -> Void)?
    
    var notificationRequestIdentifier = ""
    
    func didReceive(_ notification: UNNotification) {
        notificationRequestIdentifier = notification.request.identifier
        Euromsg.configure(appAlias: "relateddigital-flutter-example-ios", launchOptions: nil, enableLog: true)
        carouselView.didReceive(notification)
    }
    func didReceive(_ response: UNNotificationResponse, completionHandler completion: @escaping (UNNotificationContentExtensionResponseOption) -> Void) {
        carouselView.didReceive(response, completionHandler: completion)

    }
    override func loadView() {
        completion = { [weak self] url, bestAttemptContent in
            if let identifier = self?.notificationRequestIdentifier {
                UNUserNotificationCenter.current().removeDeliveredNotifications(withIdentifiers: [identifier])
                UNUserNotificationCenter.current().getDeliveredNotifications(completionHandler: { notifications in
                    bestAttemptContent?.badge =  NSNumber(value: notifications.count)
                })
            }
            if let url = url {
                if #available(iOSApplicationExtension 12.0, *) {
                    self?.extensionContext?.dismissNotificationContentExtension()
                }
                self?.extensionContext?.open(url)
            } else {
                if #available(iOSApplicationExtension 12.0, *) {
                    self?.extensionContext?.performNotificationDefaultAction()
                }
            }
        }
        carouselView.completion = completion
        carouselView.delegate = self
        self.view = carouselView
    }
}

/**
 Add if you want to track which carousel element has been selected
 */
extension EMNotificationViewController: CarouselDelegate {
    
    func selectedItem(_ element: EMMessage.Element) {
        // Add your work...
        print("Selected element is => \(element)")
    }
    
}

• In your NotificationContent/Info.plist add below section

<key>NSExtension</key>
<dict>
    <key>NSExtensionAttributes</key>
    <dict>
        <key>UNNotificationExtensionCategory</key>
        <string>carousel</string>
        <key>UNNotificationExtensionDefaultContentHidden</key>
        <false />
        <key>UNNotificationExtensionInitialContentSizeRatio</key>
        <real>1</real>
        <key>UNNotificationExtensionUserInteractionEnabled</key>
        <true />
    </dict>
    <key>NSExtensionPointIdentifier</key>
    <string>com.apple.usernotifications.content-extension</string>
    <key>NSExtensionPrincipalClass</key>
    <string>NotificationContent.EMNotificationViewController</string>
</dict>

Set Push Permit

You can only call setNotificationPermission method to enable or disable push notifications for the application.

relatedDigitalPlugin.setNotificationPermission(true);

Get-Payload-List

You can access payload list of last 30 days if you have completed iOS NotificationServiceExtension and App Groups setup. Using getPushMessages method you can access these payloads

PayloadListResponse payloadListResponse = await relatedDigitalPlugin.getPushMessages();

Data Collection

Related Digital uses events to collect data from mobile applications. The developer needs to implement the methods provided by SDK. customEvent is a generic method to track user events. customEvent takes 2 parameters: pageName and properties.

• pageName : The current page of your application. If your event is not related to a page view, you should pass a value related to the event. If you pass an empty String the event would be considered invalid and discarded.
• parameters : A collection of key/value pairs related to the event. If your event does not have additional data apart from page name, passing an empty Map acceptable.

Some of the most common events:

Sign Up

String userId = 'userId';
// optional
Map<String, String> properties = {
  'OM.b_sgnp':'1'
};

await relatedDigitalPlugin.signUp(userId, properties: properties);

Login

String userId = 'userId';
// optional
Map<String, String> properties = {
  'OM.b_login':'1'
};

await relatedDigitalPlugin.login(userId, properties: properties);

Page View

Use the following implementation of customEvent method to record the page name the visitor is currently viewing. You may add extra parameters to properties Map or you may leave it empty.

String pageName = 'Page Name';
Map<String, String> parameters = {};
await relatedDigitalPlugin.customEvent(pageName, parameters);

Product View

Use the following implementation of customEvent when the user displays a product in the mobile app.

String pageName = 'Product View';
Map<String, String> parameters = {
  'OM.pv' : productCode, 
  'OM.pn' : productName, 
  'OM.ppr' : productPrice, 
  'OM.pv.1' : productBrand, 
  'OM.inv': inventory // Number of items in stock
};
relatedDigitalPlugin.customEvent(pageName, parameters);

Add to Cart

Use the following implementation of customEvent when the user adds items to the cart or removes.

String pageName = 'Cart';
Map<String, String> parameters = {
  'OM.pbid' : basketID, 
  'OM.pb' : 'Product1 Code;Product2 Code', 
  'OM.pu' : 'Product1 Quantity;Product2 Quantity', 
  'OM.ppr' : 'Product1 Price*Product1 Quantity;Product2 Price*Product2 Quantity'
};
relatedDigitalPlugin.customEvent(pageName, parameters);

Product Purchase

Use the following implementation of customEvent when the user buys one or more items.

String pageName = 'Purchase';
Map<String, String> parameters = {
  'OM.tid' : transactionID, 
  'OM.pp' : 'Product1 Code;Product2 Code', 
  'OM.pu' : 'Product1 Quantity;Product2 Quantity', 
  'OM.ppr' : 'Product1 Price*Product1 Quantity;Product2 Price*Product2 Quantity',
  'OM.exVisitorID' : userId
};
relatedDigitalPlugin.customEvent(pageName, parameters);

Product Category Page View

When the user views a category list page, use the following implementation of customEvent.

String pageName = 'Category View';
Map<String, String> parameters = {
  'OM.clist': '12345',
};
relatedDigitalPlugin.customEvent(pageName, parameters);

In App Search

If the mobile app has a search functionality available, use the following implementation of customEvent.

String pageName = 'In App Search';
Map<String, String> parameters = {
  'OM.OSS': searchKeyword,
  'OM.OSSR': searchResult.length,
};
relatedDigitalPlugin.customEvent(pageName, parameters);

Banner Click

You can monitor banner click data using the following implementation of customEvent.

String pageName = 'Banner Click';
Map<String, String> parameters = {
  'OM.OSB': 'Banner Name/Banner Code',
};
relatedDigitalPlugin.customEvent(pageName, parameters);;

Add To Favorites

When the user adds a product to their favorites, use the following implementation of customEvent.

String pageName = 'Add To Favorites';
Map<String, String> parameters = {
  'OM.pf' : productCode, 
  'OM.pfu' : '1',
};
relatedDigitalPlugin.customEvent(pageName, parameters);

Remove from Favorites

When the user removes a product from their favorites, use the following implementation of customEvent.

String pageName = 'Add To Favorites';
Map<String, String> parameters = {
  'OM.pf' : productCode, 
  'OM.pfu' : '-1',
};
relatedDigitalPlugin.customEvent(pageName, parameters);

Logout

To remove all the user related data from local storage, use the method below.

await relatedDigitalPlugin.logout();

Targeting Actions

In-App Messaging

In-app messages are notifications to your users when they are directly active in your mobile app. To enable In-App Messaging feature you need to set the value of inAppNotificationsEnabled parameter to true when calling init to initialize the SDK.

The existence of a relevant in-app message for an event controlled by after each customEvent call. You can create and customize your in-app messages on https://intelligence.relateddigital.com/#Target/TargetingAction/TAList page of RMC administration panel.

There are 9 types of in-app messages:

Pop-up - Image, Header, Text & Button	Mini-icon&text	Full Screen-image
Full Screen-image&button	Pop-up - Image, Header, Text & Button	Pop-up-Survey
Pop-up - NPS with Text & Button	Native Alert & Actionsheet	NPS with numbers

Geofencing

IOS

• In Xcode, add NSLocationAlwaysAndWhenInUseUsageDescription and NSLocationWhenInUseUsageDescription keys to the Info.plist file.
• In Xcode, enable Background fetch and Location updates background modes.
• When initializing plugin, set geofenceEnabled to true. Also provide a number for maxGeofenceCount parameter (max. 20 supported).

Android

• Add below permissions in your AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

    android:enabled="true"
    android:exported="false"/>

Recommendation

Use getRecommendations method as below to retrieve product recommendations. This method takes mandatory zoneId and productCode parameters with optional filters parameter.

import 'package:relateddigital_flutter/recommendation_filter.dart';

Future<void> getRecommendations() async {
  String zoneId = '6';
  String productCode = '';

  // optional
  Map<String, Object> filter = {
    RDRecommendationFilter.attribute: RDRecommendationFilterAttribute.PRODUCTNAME,
    RDRecommendationFilter.filterType: RDRecommendationFilterType.like,
    RDRecommendationFilter.value: null
  };

  List filters = [
    filter
  ];

  List result = await widget.relatedDigitalPlugin.getRecommendations(zoneId, productCode);
  // List result = await relatedDigitalPlugin.getRecommendations(zoneId, productCode, filters: filters);
  print(result.toString());
}
