Netmera Flutter SDK #

NETMERA is a Mobile Application Engagement Platform. We offer a series of development tools and app communication features to help your mobile business ignite and soar.

Installation #

For using this package as a library:
  • Add this to your package's pubspec.yaml file
dependencies:
  netmera_flutter_sdk: ^x.x.x
  • You can install packages from the command line with Flutter:
$ flutter pub get

For both native sides(Android & iOS) you don't have to include extra Netmera SDK libraries.

Setup - Android Part #

  1. Create and register your app in Firebase console.

  2. Download google-services.json file and place it into android/app/ folder.

  3. In your project's build gradle file, add the following dependency.

buildscript {
    repositories {
        google()
        jcenter()
        maven {url 'https://developer.huawei.com/repo/'}
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.3'
        classpath 'com.google.gms:google-services:4.3.5'
        classpath 'com.huawei.agconnect:agcp:1.5.2.300'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven { url 'https://maven.google.com'}
        maven {url 'https://developer.huawei.com/repo/'}
    }
}
  1. In your app's build gradle file, add the following dependency.

 dependencies {
 
     implementation 'androidx.core:core:1.1.0'
     
 }
  1. Add the following into the top of app's build.gradle file
apply plugin: 'com.google.gms.google-services'
apply plugin: 'com.huawei.agconnect'
  1. Create an application class as shown below.
  • Your Application class must extends FlutterApplication.
    public class NMApp extends FlutterApplication {
    
        @Override
        public void onCreate() {
            super.onCreate();
            FNetmeraConfiguration fNetmeraConfiguration = new FNetmeraConfiguration.Builder()
                .firebaseSenderId(<YOUR GCM SENDER ID>)
                .huaweiSenderId(<YOUR HMS SENDER ID>)
                .apiKey(<YOUR NETMERA API KEY>)
                .logging(true) // This is for enabling Netmera logs.
                .build(this);
            FNetmera.initNetmera(fNetmeraConfiguration); 
        }
    }
  1. Inside dart class add the following
void main() {
  initBroadcastReceiver();
  runApp(MyApp());
}

void _onPushRegister(Map<dynamic, dynamic> bundle) async {
  print("onPushRegister: $bundle");
}

void _onPushReceive(Map<dynamic, dynamic> bundle) async {
  print("onPushReceive: $bundle");
}

void _onPushDismiss(Map<dynamic, dynamic> bundle) async {
  print("onPushDismiss: $bundle");
}

void _onPushOpen(Map<dynamic, dynamic> bundle) async {
  print("onPushOpen: $bundle");
}

void _onPushButtonClicked(Map<dynamic, dynamic> bundle) async {
  print("onPushButtonClicked: $bundle");
}

void _onCarouselObjectSelected(Map<dynamic, dynamic> bundle) async {
  print("onCarouselObjectSelected: $bundle");
}

void initBroadcastReceiver() {
  NetmeraPushBroadcastReceiver receiver = new NetmeraPushBroadcastReceiver();
  receiver.initialize(
    onPushRegister: _onPushRegister,
    onPushReceive: _onPushReceive,
    onPushDismiss: _onPushDismiss,
    onPushOpen: _onPushOpen,
    onPushButtonClicked: _onPushButtonClicked,
    onCarouselObjectSelected: _onCarouselObjectSelected
  );
}
  1. If you have custom Firebase Messaging integration, please see usage below.
FirebaseMessaging messaging = FirebaseMessaging.instance;

messaging.getToken(vapidKey: <YOUR_KEY>).then((value) {
  Netmera.onNetmeraNewToken(value);
});

FirebaseMessaging.onMessage.listen((RemoteMessage message) {
     if (Netmera.isNetmeraRemoteMessage(message.data)) {
         Netmera.onNetmeraFirebasePushMessageReceived(message.from, message.data);
     }
});   
  • If you build your project with flutter run --release, please add @pragma('vm:entry-point') annotation to your _firebaseMessagingBackgroundHandler method as in the following code block.
@pragma('vm:entry-point')
Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage remoteMessage) async {
// handle message
}
  1. If you have custom Huawei Messaging integration, please see usage below.
Push.getTokenStream.listen((String token) {
  Netmera.onNetmeraNewToken(token);
});

Push.onMessageReceivedStream.listen((RemoteMessage remoteMessage) {
  Map<String, String> map = remoteMessage.dataOfMap ?? new Map();
  if (Netmera.isNetmeraRemoteMessage(map)) {
    Netmera.onNetmeraHuaweiPushMessageReceived(remoteMessage.from, map);
  }
});

Setup - iOS Part #

  1. Navigate to ios folder in your terminal and run the following command.
$ pod install
  1. If you are using Swift, enter the following in your Runner-Bridging-Header.h.
#import "FNetmera.h"
#import "FNetmeraService.h"
#import "NetmeraFlutterSdkPlugin.h"
  1. If you want to use Android alike message sending from iOS to dart please consider to shape your AppDelegate class as following.
import UIKit
import Flutter

//This function is needed for sending messages to the dart side. (Setting the callback function)
func registerPlugins(registry: FlutterPluginRegistry) {
    GeneratedPluginRegistrant.register(with: registry)
};

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate,UNUserNotificationCenterDelegate,NetmeraPushDelegate {

    override func application(_ application: UIApplication,
                didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    GeneratedPluginRegistrant.register(with: self)

        if #available(iOS 10.0, *) {
        UNUserNotificationCenter.current().delegate = self
    } else {
        // Fallback on earlier versions
    };

        //For triggering onPushReceive when app is killed and push clicked by user
        let notification = launchOptions?[.remoteNotification]
        if notification != nil {
            self.application(application, didReceiveRemoteNotification: notification as! [AnyHashable : Any])
        }

    //This function is needed for sending messages to the dart side.
    NetmeraFlutterSdkPlugin.setPluginRegistrantCallback(registerPlugins)

    FNetmera.logging(true) // Enable Netmera logging
    FNetmera.initNetmera("<YOUR-NETMERA-KEY>") //Initializing Netmera packages.
    FNetmera.setPushDelegate(self) //
    Netmera.setAppGroupName("group.com.netmera.flutter") // Your app group name

    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }


    override func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        FNetmeraService.handleWork(ON_PUSH_REGISTER, dict: ["pushToken": deviceToken])
    }

    override func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {
        FNetmeraService.handleWork(ON_PUSH_RECEIVE, dict:["userInfo" : userInfo])
    }


    @available(iOS 10.0, *)
    func userNotificationCenter(_ center: UNUserNotificationCenter,
                                didReceive response: UNNotificationResponse,
                                withCompletionHandler completionHandler:
        @escaping () -> Void) {

        if response.actionIdentifier == UNNotificationDismissActionIdentifier {
            FNetmeraService.handleWork(ON_PUSH_DISMISS,dict:["userInfo" : response.notification.request.content.userInfo])
        }
        else if response.actionIdentifier == UNNotificationDefaultActionIdentifier {
            FNetmeraService.handleWork(ON_PUSH_OPEN, dict:["userInfo" : response.notification.request.content.userInfo])
        }
        completionHandler()
    }

    @available(iOS 10.0, *)
    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        completionHandler([UNNotificationPresentationOptions.alert])
    }
}

For example if you trigger FNetmeraService.handleWork(ON_PUSH_RECEIVE, dict:["userInfo" : userInfo]) from AppDelegate, in the dart part the following method will be triggered.

void _onPushReceive(Map<dynamic, dynamic> bundle) async {
  print("onPushReceive: $bundle");
}

Please take a look at Setup-Android part 8

  1. In order to use iOS10 Media Push, follow the instructions in Netmera Product Hub.

Calling Dart methods #

Update User Example
updateUser() {
    NetmeraUser user = new NetmeraUser();
    user.setUserId(userController.text);
    user.setName(nameController.text);
    user.setSurname(surnameController.text);
    user.setEmail(emailController.text);
    user.setMsisdn(msisdnController.text);
    user.setGender(int.parse(_selectedGender));
    Netmera.updateUser(user);
  }
Sending Event Examples
  void sendLoginEvent() {
    NetmeraEventLogin loginEvent = new NetmeraEventLogin();
    Netmera.sendEvent(loginEvent);
  }

  void sendRegisterEvent() {
    NetmeraEventRegister registerEvent = new NetmeraEventRegister();
    Netmera.sendEvent(registerEvent);
  }

  void sendViewCartEvent() {
    NetmeraEventCartView cartViewEvent = new NetmeraEventCartView();
    cartViewEvent.setItemCount(3);
    cartViewEvent.setSubTotal(15.99);
    Netmera.sendEvent(cartViewEvent);
  }

  void sendPurchaseEvent() {
    NetmeraLineItem netmeraLineItem = NetmeraLineItem();
    netmeraLineItem.setBrandId("TestBrandID");
    netmeraLineItem.setBrandName("TestBrandName");
    netmeraLineItem.setCampaignId("TestCampaignID");
    netmeraLineItem.setCategoryIds(["TestCategoryID1", "TestCategoryID2"]);
    netmeraLineItem.setCategoryNames(
        ["TestCategoryName1", "TestCategoryName2", "TestCategoryName3"]);
    netmeraLineItem.setKeywords(["keyword1", "keyword2", "keyword3"]);
    netmeraLineItem.setCount(12);
    netmeraLineItem.setId("TestItemID");
    netmeraLineItem.setPrice(130);

    // CustomPurchaseEvent extends PurchaseEvent
    CustomPurchaseEvent purchaseEvent = CustomPurchaseEvent();
    // Set default attributes
    purchaseEvent.setCoupon("Test_Coupon");
    purchaseEvent.setDiscount(10);
    purchaseEvent.setItemCount(2);
    purchaseEvent.setPaymentMethod("Credit Card");
    purchaseEvent.setSubTotal(260.89);
    purchaseEvent.setShippingCost(0.0);
    purchaseEvent.setLineItems([netmeraLineItem, netmeraLineItem]);

    // Set custom attributes
    purchaseEvent.setInstallment("test installment");
    Netmera.sendEvent(purchaseEvent);
  }
  
  void sendTestEvent() {
    //Custom event
    TestEvent testEvent = TestEvent();
    testEvent.setNo(3); //Custom attribute
    Netmera.sendEvent(testEvent);
  }
Push Notification Permissions

If you don't request notification permission at runtime, you can request it by calling the requestPushNotificationAuthorization() method. Note: Notification runtime permissions are required on Android 13 (API 33) or higher. Therefore, before calling the method, make sure your project targets an API of 33 and above.

 Netmera.requestPushNotificationAuthorization();

You can call the areNotificationsEnabled() method if you need to know the status of permissions.

 Netmera.areNotificationsEnabled().then((enabled) {
      // Use the enabled status of permission as boolean
 });
