You may also track errors with the Firebase Crashlytics plugin, which provides an overview of your app’s stability and allows you to fix bugs simply by tracking the errors.

This feature is primarily about critical alerting metrics like “crash-free users” that are designed to help you keep track of your application’s stability.
