How do you implement robust error handling and crash reporting globally?

Updated Apr 28, 2026

Short answer

By catching Dart errors, Flutter framework errors, and asynchronous errors centrally using zones and bindings.

Catch UI rendering errors via FlutterError.onError. 2. Catch asynchronous Dart errors by wrapping runApp in runZonedGuarded. 3. Catch platform/engine errors via PlatformDispatcher.instance.onError. Send these caught exceptions to a reporting service like Firebase Crashlytics or Sentry.
