Step 1: Flutter Installation

To use this package as a library in your Flutter project, follow these steps:
  1. 1.
    Add the following lines to your project's pubspec.yaml file under the dependencies section.
dependencies:
netmera_flutter_sdk: ^x.x.xg
  1. 2.
    You can install packages from the command line with Flutter:
$ flutter pub get
You don't need to include extra Netmera SDK libraries for both native sides (Android & iOS).

Step 2: Setup / Android

  1. 1.
    Firebase Cloud Messaging:
Netmera uses Firebase Cloud Messaging (FCM) to deliver push messages to the Android devices. Therefore, you should create and configure a project on Firebase Developers Console.
  1. 2.
    Download Configuration Files:
Download the google-services.json file and place it into the Android > App > Folder.
  1. 3.
    Update Gradle Files:
In your project's build.gradle file, add the following dependencies.
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/'}
}
}
In your app's build gradle file, add the following dependency.
dependencies {
implementation 'androidx.core:core:1.1.0'
}
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. 4.
    Create Application Class (Java):
Create an application class that extends FlutterApplication.
Replace <YOUR GCM SENDER ID>, <YOUR HMS SENDER ID>, and <YOUR NETMERA API KEY> with your actual values.
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. 5.
    Inside Dart Class:
Inside your Dart class, add the following code to set up event handlers:
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. 6.
    Custom Firebase Messaging Integration:
If you have a custom Firebase Messaging integration, use the following code:
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);
}
});
Important Note:
If you're building your Flutter project with flutter run --release and need to add the @pragma('vm:entry-point') annotation to the _firebaseMessagingBackgroundHandler method, you can modify the code block as follows.
Adding the @pragma('vm:entry-point') annotation ensures that this method is correctly recognized as an entry point when building your project in release mode. This is important for background message handling in Flutter, and the annotation helps Flutter identify and execute the method as expected.
@pragma('vm:entry-point')
Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage remoteMessage) async {
// handle message
}
  1. 7.
    Custom Huawei Messaging Integration:
If you have a custom Huawei Messaging integration, use the following code.
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);
}
});

Step 3: Setup / iOS

To set up Netmera for iOS, follow these steps:
  1. 1.
    Navigate to the "iOS" folder in your terminal and run the following command to install dependencies:
$ pod install
  1. 2.
    If you're using Swift, you'll need to include the following imports in your Runner-Bridging-Header.h file.
#import "FNetmera.h"
#import "FNetmeraService.h"
#import "NetmeraFlutterSdkPlugin.h"
  1. 3.
    If you want to enable Android-like message sending from iOS to Dart, consider configuring your AppDelegate class as follows.
import UIKit
import Flutter
​
@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])
}
​
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])
if UIApplication.shared.applicationState == .active {
FNetmeraService.handleWork(ON_PUSH_RECEIVE, dict:["userInfo" : userInfo])
} else {
FNetmeraService.handleWork(ON_PUSH_RECEIVE_BACKGROUND, 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 instance, if you trigger FNetmeraService.handleWork(ON_PUSH_RECEIVE, dict:["userInfo" : userInfo]) from AppDelegate, the following Dart method will be triggered
void _onPushReceive(Map<dynamic, dynamic> bundle) async {
print("onPushReceive: $bundle");
}

If you use onPrem set baseUrl,
Netmera.setBaseUrl("")
