-- [Source code context](/docs/error-tracking/stack-traces) associated with an exception
-- Flutter web support

+This configuration is client-side only. Support for remote configuration in the [error tracking settings](https://app.posthog.com/settings/project-error-tracking#exception-autocapture) will be added in a future release.

+
+You can autocapture exceptions by configuring the `errorTrackingConfig` when setting up PostHog:
+
+```dart
+final config = PostHogConfig('<ph_project_api_key>');
+
+// Enable exception autocapture
+config.errorTrackingConfig.captureFlutterErrors = true;
+config.errorTrackingConfig.capturePlatformDispatcherErrors = true;
+config.errorTrackingConfig.captureIsolateErrors = true;
+config.errorTrackingConfig.captureNativeExceptions = true; // Android only
+config.errorTrackingConfig.captureSilentFlutterErrors = false;
+
+await Posthog().setup(config);
+```
+
+**Configuration options:**
+
+- **`captureFlutterErrors`**: Captures Flutter framework errors (FlutterError.onError)
+- **`capturePlatformDispatcherErrors`**: Captures Dart runtime errors (PlatformDispatcher.onError)
+- **`captureIsolateErrors`**: Captures errors from main isolate
+- **`captureNativeExceptions`**: Captures native exceptions (Android only - Java/Kotlin exceptions)
+- **`captureSilentFlutterErrors`**: Captures Flutter errors that are marked as silent (default: false)
