Integrate with Firebase

If you are using the Firebase SDK next to the justtrack SDK, you can use the justtrack SDK to send the Firebase app instance ID of a user to the justtrack backend. You can then later send events from the justtrack backend to Firebase to measure events happening outside of your app. To send these events, the justtrack backend needs the Firebase app instance ID of the user. You can send this by calling sdk.set(firebaseAppInstanceId: firebaseAppInstanceId), but of course this requires you to add additional boilerplate code to your app.

To help you here, the justtrack SDK offers the sdk.integrateWithFirebase() method.
