Set Superpowers.observer in main() before runApp() to start receiving events for mix() calls.

Frequently Asked Questions about setup-observer

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I track mix() operations in Flutter for debugging and performance telemetry?▼

Track mix() operations by setting Superpowers.observer to capture start, end, duration, and outcome events. This centralizes observation of all mix() executions across cubits and blocs for consistent debugging and telemetry.

What is the best way to monitor cubit and bloc performance in Dart apps?▼

Monitor cubit and bloc performance by configuring a centralized observer to standardize observation of all mix() calls. It captures timing, errors, and success states to enable real-time debugging and analytics.

Where do I configure a global observer for mix() tracking in a Flutter application?▼

Configure the global observer for mix() tracking in your main() function before runApp(). Setting Superpowers.observer before runApp() ensures all subsequent mix() events are captured.

Can I capture errors and timing data from mix() calls during production?▼

Yes, you can capture errors and timing data from mix() calls during production by handling the observer callback. It processes metrics, errors, and timing data for telemetry integration across your app.

Does setting up mix() observation require any specific dependencies in bloc_superpowers?▼

Setting up mix() observation requires using the bloc_superpowers package in your Flutter or Dart app. You assign Superpowers.observer before runApp() and handle its callback to process the telemetry data.
