Flutter Performance and Reliability

When to use

Invoke when defining and enforcing performance budgets for a scaffolded Flutter app, instrumenting startup/frame/memory/battery and crash-free/ANR telemetry, adding performance-regression CI gates, or verifying graceful-degradation behavior under low memory, poor network, and battery saver.

Do not use for: app scaffolding or the error-handling layers themselves (use flutter-app-scaffold-and-runtime); navigation, state, or design-system work (use the respective Flutter archetype skills). This skill gates those archetypes; it does not implement them.

Inputs

Required:

• A scaffolded Flutter app with the performance-tracing seam (perf_tracer.dart) and crash-reporting seam (crash_reporter.dart) in place.
• Approved mobile-architecture.md, or explicit confirmation that mobile architecture is intentionally deferred.

Optional:
