PostHog error tracking for Flutter

— the description by PostHog

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides guidance on integrating PostHog error tracking into Flutter applications. It covers the implementation of exception autocapture, manual error boundary handling, and the importance of uploading source maps for readable stack traces. The skill also details how to manage issues through assignment rules and configure alerts to stay informed about application stability.

What it does

Guides the integration of PostHog error tracking into Flutter apps
Explains how to enable exception autocapture for automatic error reporting
Provides patterns for manual error capture at boundaries
Details how to upload source maps for unminified stack traces
Describes how to set up automated issue assignment and alerting
Outlines best practices for environment variable usage and SDK initialization

When to use it

When you need to monitor runtime errors in a Flutter application
When you want to automate the triage and assignment of reported issues
When you need to receive notifications for specific error spikes or new issues
When you need to resolve minified stack traces to original source code

Advantages

Centralizes error reporting and management within the PostHog platform
Supports automated workflows for team-based issue assignment
Enables proactive monitoring through configurable spike and trend alerts
Maintains clean code by recommending non-intrusive error handling patterns

Usage examples

“How do I set up PostHog error tracking in my Flutter app?”: The agent provides steps to initialize the SDK, enable autocapture, and ensure environment variables are used for configuration.
“How can I notify my team when a new error occurs in Flutter?”: The agent explains how to configure alerting rules in the PostHog error tracking dashboard to send notifications to Slack or other channels.

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.

Framework guidelines

No specific framework guidelines.
