How to Get Airship Device Token for iOS and gcm_registration_id for Android with Flutter

When working with push notifications in your Flutter applications, you may find yourself needing specific device tokens from Urban Airship. These tokens are essential for sending targeted notifications to users. If you’re looking to retrieve the Airship device token for iOS and gcm_registration_id for Android, you're in the right place! This guide will walk you through the process step-by-step, ensuring that you can integrate these tokens seamlessly into your application.

Understanding the Problem

While working within Flutter, developers often utilize the Firebase Messaging package to handle push notifications. However, many have encountered the issue of the token retrieved using Firebase being different from the one provided by Urban Airship. Understanding how to properly obtain the correct tokens for both iOS and Android is necessary for ensuring that your notifications reach your intended audience.

Retrieving Device Tokens with Flutter

For iOS: Getting the Airship Device Token

To retrieve the device token for iOS, you will be utilizing the FirebaseMessaging class. By executing the following line of code, you can obtain the token necessary for Airship integration:

Explanation: This command requests the Apple Push Notification service (APNs) token, which is what Urban Airship requires for iOS devices. Make sure you handle the function asynchronously since it involves waiting for a response from the service.

For Android: Getting the gcm_registration_id

For Android devices, you will again use the FirebaseMessaging class to retrieve the gcm_registration_id. Here is the code snippet you need:

Explanation: The getToken() method fetches the token needed to register with Google Cloud Messaging (GCM), which Urban Airship uses for sending notifications to Android devices.

Important Considerations

Firebase versus Urban Airship Tokens: Remember that the tokens you obtain through Firebase Messaging may vary from the tokens linked specifically to Urban Airship. Always ensure that you’re using the right method to access Urban Airship’s API.

Handling Tokens: After obtaining the device tokens, store them securely and utilize them within your app. You may need to send the tokens to your backend server or manage them within your app logic to ensure users receive announcements and notifications accordingly.

Permissions: Ensure that your app has the appropriate permissions to receive notifications. For iOS, this means asking for permission to enable notifications upon app launch.

Conclusion

Retrieving the Airship device token for iOS and gcm_registration_id for Android in Flutter may seem daunting at first, but with the given code snippets and understanding of the underlying process, it can be accomplished with ease. Utilizing these tokens correctly will allow you to establish effective push notification functionality within your Flutter applications. If you have further questions or run into issues, don’t hesitate to refer to Urban Airship’s documentation or the Flutter community for additional support.

Now you are ready to integrate Urban Airship's powerful notification system into your Flutter apps! Happy coding!
