With the Fyno SDK installed, let's cover how to initialise it, identify users, register for push notifications, and handle other functionalities.

Initialising the SDK (to be called on app launch)

📘

Distinct ID is an ID that is associated with a specific user and is unique to that user. No two user profiles can have the same Distinct ID.

To initialise the Fyno SDK, you need to provide the following information:

  • Workspace ID: Your unique Fyno workspace ID, available on the Workspace Settings page.
  • Integration ID: The ID of the integration created in Fyno Integrations.
  • Distinct ID: A unique identifier for your user. If not provided, a UUID is automatically generated.
  • Version: Indicates the environment in which the user is created. Default is "live", but you can set it to "test" for testing purposes.

In your main Dart file, import the fyno_flutter package and call FynoFlutter.init() to initialise the SDK:

import 'package:fyno_flutter/fyno_flutter.dart';

void main() {
    ...
    Exception? initException = await FynoFlutter.init(
        'workspaceId',
        'integrationId',
        'distinctId',
        'version',
    );

    if (initException != null) {
        // Handle initialization error
        print("Initialization error: $initException");
    } else {
        // Initialization successful
    }
    ...
}

Identifying the User

To update/set a distinct ID or user name, you can call FynoFlutter.identify().

  • Distinct ID:: The distinct ID you want to identify the user with.
  • User Name: The name you want to assign to the user.
Exception? identifyException = await FynoFlutter.identify('distinctId', 'userName');

if (identifyException != null) {
    // Handle identification error  
    print("Identification error: $identifyException");
} else {  
    // User identification successful  
}

Updating user profile name

To update/set only the name for a user profile, you can call FynoFlutter.updateName()

  • User Name: The name you want to assign to the user.
Exception? updateUserNameException = await FynoFlutter.updateName('userName');

if (updateUserNameException != null) {
    // Handle updateUserName error  
    print("User Name Update Exception: $updateUserNameException");
} else {  
    // User identification successful  
}

Registering for Push Notifications

To register the application for push notifications, call FynoFlutter.registerPush().

APNs or Google FCM

  • To register for push notifications with APNs or Google FCM, you need to specify the provider type.
  • Use apns if APNs is configured or fcm if Google FCM is configured in the integration.
Exception? pushRegistrationException = await FynoFlutter.registerPush(  
  'provider', // has to be either apns or fcm
);

if (pushRegistrationException != null) {  
    // Handle push registration error  
    print("Push registration error: $pushRegistrationException");  
} else {  
    // Push registration successful  
}

For Google FCM, ensure you've followed the Firebase setup mentioned earlier and have added the google-services.json or GoogleService-Info.plist file to your project root.

Xiaomi Services (Android only)

  • To register for push notifications with Xiaomi, provide the Xiaomi application ID and key, along with the push region.
  • Xiaomi Application Id and Xiaomi Application Key are mandatory fields which can be found under the application registered at Xiaomi Admin.
  • Push Region: Refers to the geographical region where push notifications are delivered.
  • Provider: Use xiaomi.
Exception? pushRegistrationResult = FynoFlutter.registerPush(
    'xiaomi',
    xiaomiApplicationId: 'xiaomiApplicationId',
    xiaomiApplicationKey: 'xiaomiApplicationKey',
    pushRegion: 'pushRegion', // one of ‘INDIA’,’EUROPE’,’RUSSIA’,’GLOBAL’,
);

if (pushRegistrationResult != null) {  
    // Handle push registration error  
    print("Push registration error: $pushRegistrationResult");  
} else {  
    // Push registration successful  
}

Fetch push notification token

If you want to fetch the push notification token for the current device, use FynoFlutter.getNotificationToken()

String? notificationToken = await FynoFlutter.getNotificationToken();
if(notificationToken != null) {
  print("Notification token: $notificationToken");
}

Check if notification received is from Fyno and also handle it

To check if the push notification received is from Fyno, use FynoFlutter.isFynoNotification(messageData) and to handle it, use FynoFlutter.handleFynoNotification()

  • message: an instance of Firebase RemoteMessage

🚧

These functions are available only in Android

// to receive and handle notifications when the application is in background or killed state
FirebaseMessaging.onBackgroundMessage((RemoteMessage message) async {
  if (await FynoFlutter.isFynoNotification(message.toMap())) {
    await FynoFlutter.handleFynoNotification(message.toMap());
  } else {
    // any other logic to handle the notification
  }
});

// to receive and handle notifications when the application is in foreground state
FirebaseMessaging.onMessage.listen((RemoteMessage message) async {
  if (await FynoFlutter.isFynoNotification(message.toMap())) {
    await FynoFlutter.handleFynoNotification(message.toMap());
  } else {
    // any other logic to handle the notification
  }
});

Merging User Profiles

If you need to merge two user profiles, call FynoFlutter.mergeProfile() with the old and new distinct IDs.

Exception? mergeException = await FynoFlutter.mergeProfile(  
    'oldDistinctId',  
    'newDistinctId',  
);

if (mergeException != null) {  
    // Handle user profile merge error  
    print("User profile merge error: $mergeException");  
} else {  
    // User profile merge successful  
}

Updating Message Status

You can update the status of a notification (received, clicked or dismissed) using FynoFlutter.updateStatus().

  • Callback URL: You can obtain the Callback URL from the notification additional payload if the notification was triggered from Fyno.
  • Status: The status of the notification (one of RECEIVED, CLICKED or DISMISSED).
Exception? updateStatusException = await FynoFlutter.updateStatus(  
    'callbackUrl',  
    'status',
);

if (updateStatusException != null) {  
    // Handle user status update error  
    print("User status update error: $updateStatusException");  
} else {  
    // User status update successful
}

Resetting User Information

To reset user information, call FynoFlutter.resetUser().

  • You can invoke this function when the user logs out of the application.
  • It handles the deletion of channel data associated with the current user, initiates the creation of a fresh user profile, and transfers the channel data to the newly created profile.
  • This feature proves to be invaluable if you plan to send push notifications to an application where the user has logged out.
Exception? resetUserException = await FynoFlutter.resetUser();

if (resetUserException != null) {  
    // Handle user information reset error  
    print("User information reset error: $resetUserException");  
} else {  
    // User information reset successful  
}

Sample initialisation

// initialise

Exception? initException = await FynoFlutter.init(
    'workspaceId',
    'integrationId',
    'distinctId',
    'version',
);

if (initException != null) {
    // Handle initialization error
    print("Initialization error: $initException");
} else {
    // Initialization successful
}

// identify user
Exception? identifyException = await FynoFlutter.identify('distinctId', 'userName');

if (identifyException != null) {  
    // Handle identification error  
    print("Identification error: $identifyException");
} else {  
    // User identification successful  
}

// register with APNs
Exception? pushRegistrationException = await FynoFlutter.registerPush(  
    'apns',
);

if (pushRegistrationException != null) {  
    // Handle push registration error  
    print("Push registration error: $pushRegistrationException");  
} else {  
    // Push registration successful  
}
