## Track screen views
Recommended
Despite the name, the web analytics dashboard can be used to track screen views in mobile apps, too. Open your app and view some screens to generate some events.
To automatically capture screen views, you can use the `PostHogObserver` with your navigation:
Dart
PostHog AI
```dart
import 'package:posthog_flutter/posthog_flutter.dart';
MaterialApp(
navigatorObservers: [
PosthogObserver(),
],
// rest of your app
)
```

## Next steps
Recommended
After installing PostHog and ensuring [autocapture](/docs/data/autocapture.md) is enabled, head to your [web analytics dashboard](/docs/web-analytics/dashboard.md) to see your data. And then check out our [getting started](/docs/web-analytics/getting-started.md) guide.
> **PostHog tip:** Web analytics works with [anonymous events](/docs/data/anonymous-vs-identified-events.md). This means if you are primarily using PostHog for web analytics, it can be significantly cheaper for you.
