How do I use a crash reporting service like Firebase Crashlytics to track Flutter error popups in production?

Integrate the Firebase Crashlytics Flutter plugin into your project. Initialize Crashlytics in your `main()` function. Wrap potentially error-prone code in `try-catch` blocks and use `Crashlytics.log()` or `Crashlytics.recordError()` to report errors and exceptions. Crashlytics will collect crash reports and provide insights into the causes of errors.
