# Error Tracking Flutter

> Sets up PostHog error tracking in Flutter apps using the PostHog Flutter SDK, covering SDK initializ

Sets up PostHog error tracking in Flutter apps using the PostHog Flutter SDK, covering SDK initialization with exception autocapture, captureException() calls in catch blocks, error fingerprints, alerts, issue monitoring and assignment, and uploading source maps so stack traces in Dart code resolve to original source. Use when adding or configuring PostHog error tracking, exception capture, or crash reporting in a Flutter project, or when setting up PostHog issue alerts, fingerprints, or source map uploads.

# PostHog error tracking for Flutter

This skill helps you add PostHog error tracking to Flutter applications.

Consult the documentation for API details and framework-specific patterns.

## Key principles

- **Environment variables**: Always use environment variables for PostHog keys and host URLs. Never hardcode them.
- **Minimal changes**: Add error tracking alongside existing error handling. Don't replace or restructure existing error handling code.
- **Autocapture first**: Enable exception autocapture in the SDK initialization before adding manual captures.
- **Source maps**: Upload source maps so stack traces resolve to original source code, not minified bundles.
- **Manual capture for boundaries**: Use `captureException()` at error boundaries and catch blocks for errors that don't propagate to the global handler.
