For more information checkout our website and documentation.

Installation

Add WebEngage Flutter Plugin

  • Add webengage_flutter in your pubspec.yaml file.
dependencies:
webengage_flutter: 1.0.1
  • Run flutter packages get to install the SDK

Initialization

Android

  1. Initialize WebEngage in main.dart in initState();
WebEngagePlugin _webEngagePlugin = new WebEngagePlugin();
  1. Initialize WebEngage Android SDK in your <your-project>/android/app/src/main/java/<your-package-path>/MainApplication.java class.
...
import com.webengage.sdk.android.WebEngageActivityLifeCycleCallbacks;
import io.flutter.app.FlutterApplication;

public class MainApplication extends FlutterApplication {
    @Override
    public void onCreate() {
        super.onCreate();
         WebEngageConfig webEngageConfig = new WebEngageConfig.Builder()
                .setWebEngageKey("YOUR_LICENCSE_CODE")
                .setAutoGCMRegistrationFlag(false)
                .setLocationTrackingStrategy(LocationTrackingStrategy.ACCURACY_BEST)
                .setDebugMode(true) // only in development mode
                .build();
        WebengageInitializer.initialize(this,webEngageConfig);
        ...
    }
    ...
}

  1. Add below dependencies in app-level build gradle
    implementation platform('com.google.firebase:firebase-bom:25.12.0')
    implementation 'com.google.firebase:firebase-analytics'
    implementation 'com.google.firebase:firebase-messaging:20.2.1'
    implementation 'com.google.android.gms:play-services-ads:15.0.1'
  1. Add the following to your dependencies section in project/build.gradle
        classpath 'com.google.gms:google-services:4.3.4'
  1. Firebase tokens can be passed to WebEngage using FirebaseMessagingService
import com.google.firebase.messaging.FirebaseMessagingService;
import com.webengage.sdk.android.WebEngage;

public class MyFirebaseMessagingService extends FirebaseMessagingService {
    @Override
    public void onNewToken(String s) {
        super.onNewToken(s);
        WebEngage.get().setRegistrationID(s);
    }
}

It is also recommended that you pass Firebase token to WebEngage from onCreate of your Application class as shown below. This will ensure that changes in user’s Firebase token are communicated to WebEngage.

import com.google.android.gms.tasks.OnSuccessListener;
import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.InstanceIdResult;
import com.webengage.sdk.android.WebEngage;

public class MainApplication extends FlutterApplication {
    @Override
    public void onCreate() {
        super.onCreate();
    
        FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener(new OnSuccessListener<InstanceIdResult>() {
            @Override
            public void onSuccess(InstanceIdResult instanceIdResult) {
                String token = instanceIdResult.getToken();
                WebEngage.get().setRegistrationID(token);
            }
        });
    }
}
  1. Pass Messages to WebEngage Create a class that extends FirebaseMessagingService and pass messages to WebEngage. All incoming messages from WebEngage will contain key source with the value as webengage.
package your.application.package;

import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;
import com.webengage.sdk.android.WebEngage;

public class MyFirebaseMessagingService extends FirebaseMessagingService {
  @Override
  public void onMessageReceived(RemoteMessage remoteMessage) {
    Map<String, String> data = remoteMessage.getData();
    if(data != null) {
      if(data.containsKey("source") && "webengage".equals(data.get("source"))) {
        WebEngage.get().receive(data);
      }
    }
  }
}

Next, register the service to the application element of your AndroidManifest.xml as follows.

<service
    android:name=".MyFirebaseMessagingService">
    <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT"/>
    </intent-filter>
</service>

iOS

  1. Add WebEngage configurations <your-project>/ios/<YourApp>/Info.plist file.
<dict>
	<key>WEGLicenseCode</key>
	<string>YOUR-WEBENGAGE-LICENSE-CODE</string>

	<key>WEGLogLevel</key>
	<string>VERBOSE</string>
    ...
</dict>
  1. Initialize WebEngage iOS SDK in <your-project>/ios/<YourApp>/AppDelegate.m file.
#import <WebEngage/WebEngage.h>
...

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary * launchOptions {
    ...
  
    [[WebEngage sharedInstance] application:application didFinishLaunchingWithOptions:launchOptions];
    
  return [super application:application didFinishLaunchingWithOptions:launchOptions];
}

@end
