analytics

A guide for adding product analytics and crash reporting to Flutter apps using services such as Firebase, Crashlytics, Sentry, or PostHog. Analytics records app usage, while crash reporting records failures for debugging.

In plain words
What is it for?
Use it to track events, user properties, and screen views; report crashes and errors; switch providers; and plan consent or privacy requirements.
Why use it?
It helps developers choose and connect tracking and error-reporting services instead of designing the integration from scratch.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

analytics scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/upload_dsyms_crashlytics.sh, scripts/upload_dsyms_sentry.sh, scripts/upload_mapping_android.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Analytics & Crash Reporting

Track user behavior, monitor app health, and debug production issues. Supports multiple providers with a plug-and-play architecture.

When to Use This Skill

  • Adding analytics to a Flutter app
  • Setting up crash/error reporting
  • Implementing custom event tracking
  • Switching analytics providers
  • User asks "add analytics", "track events", "crash reporting", "Sentry", or "PostHog"

Questions to Ask

  1. Analytics provider: Firebase Analytics (default), PostHog, or Mixpanel?
  2. Error tracking provider: Firebase Crashlytics (default) or Sentry?
  3. Analytics scope: Full analytics (events + properties + screens) or just crash reporting?
  4. Custom events: What key user actions need tracking? (purchases, signups, feature usage)
  5. Privacy: GDPR/CCPA compliance needed? User consent flow required?

Provider Quick Reference

Need Recommended Why
Just get started Firebase Free, easy setup
Better product analytics PostHog Funnels, retention, session replay
Better error tracking Sentry Superior debugging
Data ownership PostHog (self-hosted) Your servers

See: providers-guide.md for detailed comparison.

Reference Files

  • reference/services/ - Provider-agnostic interface + implementations (Firebase, Sentry, PostHog)
  • reference/repositories/ - Domain interface + implementations
  • reference/providers/ - Riverpod state management
  • reference/failures/ - Sealed Failure types
  • reference/utils/ - Route observer, consent helpers

Workflow

Phase 1: Choose Providers

  1. Select analytics provider (Firebase Analytics / PostHog / Mixpanel)
  2. Select error tracking provider (Crashlytics / Sentry)
  3. Add dependencies to pubspec.yaml

Phase 2: Platform Config

Firebase:

  • Add GoogleService-Info.plist (iOS) and google-services.json (Android)
  • Configure dSYM upload for Crashlytics

Sentry:

  • Get DSN from Sentry dashboard
  • Configure sentry-cli for dSYM upload

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
