Have you ever worked with analytics (Crashlytics, Firebase)?

Yes, I have worked with analytical tools such as Crashlytics and Firebase. Crashlytics helps track and analyze application crashes by providing detailed crash reports, which allows for quick identification and fixing of errors. Firebase Analytics is used to collect data on user behavior, helping to improve the product based on real metrics.

For example, with Crashlytics, you can set up automatic crash report submissions and see the conditions under which crashes occur, while Firebase allows tracking events such as button clicks or level completions in a game.
