Question 1

How to integrate Sentry SDK in a Flutter app?

Accepted Answer

Add the sentry_flutter package to your pubspec.yaml, initialize it in main.dart with your DSN, and configure platform-specific settings. The README links to detailed Flutter docs for step-by-step setup.

Question 2

Sentry vs Firebase Crashlytics for error tracking in Flutter?

Accepted Answer

Sentry offers deeper Dart/Flutter integration with performance monitoring and library-specific packages, while Firebase Crashlytics is simpler but tied to Google's ecosystem. Sentry is better for comprehensive insights, but Crashlytics might suffice for basic crash reporting.

Question 3

Does Sentry Dart SDK support web applications?

Accepted Answer

Yes, the SDK supports Dart web applications through the base sentry package, but for Flutter web, use sentry_flutter. However, web support may have limitations compared to mobile platforms.

Question 4

How to reduce Sentry SDK size in Flutter build?

Accepted Answer

You can minimize size by using only necessary packages (e.g., avoid sentry_logging if not needed) and enabling tree-shaking in release builds. The SDK adds 1-1.5 MB, but careful configuration can help optimize.

Question 5

Can I use Sentry SDK with Riverpod or Bloc?

Accepted Answer

Yes, but there's no dedicated package; you'll need to manually instrument errors in state management logic. Sentry provides APIs for custom events, but integration requires more work compared to supported libraries like Dio.

Question 6

What are the costs of using Sentry for a Flutter app?

Accepted Answer

Sentry has a free tier with limited events and features, but production use often requires paid plans for higher volumes, advanced performance monitoring, and team collaboration. Costs scale with event volume and retention needs.
