​
Setup Firebase Cloud Messaging

To make use of Gleap Push Notifications you must add the Firebase Cloud Messaging service to your app or website. Learn how to get started with FCM here.

​

​
Subscribe to the Gleap user topic

The last step to complete the push notification setup is to subscribe to the user topic, which Gleap will send the push notifications to. In order to do so, you will need to register the register & unregister push message topic callbacks.
Please note that these callbacks should be called before initializing Gleap.

​
Handle push-notifications click

To handle push notifications, you will need to register a callback handler for the onMessage, onMessageOpenedAppHandler and onBackgroundMessageHandler callbacks.
That’s it - build and run your app 🚀

​
Notification images

When a changelog or news article with a featured image is sent as a push notification, Gleap includes the image in the FCM payload.
  • Android displays the image automatically when the notification arrives while your app is in the background — no setup required.
  • iOS requires a Notification Service Extension in your app to display the image. Follow the native setup in the iOS push notification guide — the extension is added to the iOS project in Xcode and works unchanged in a Flutter app.
