fluttrace 1.0.3

Production-grade frame timing analytics for Flutter. p50/p95/p99 metrics, jank detection, and a pluggable transport pipeline.

1.0.3

• Feature: PerfThresholds now dynamically resolves the device's hardware refresh rate natively, automatically adapting FPS and jank calculations to 120Hz/ProMotion displays without configuration.

1.0.2

• Feature: FluttraceOverlay is now continuously draggable across the screen.
• Fix: FPS estimation metric heavily improved. FPS is now accurately calculated using active frame durations rather than wall-clock time, preventing misleading drops in the metric when the app is idle.
• Fix: Frame timestamps now use the engine's exact FramePhase.buildStart rather than DateTime.now() to prevent inaccuracies from asynchronous batch delivery of frame timings.

1.0.1

• Fix: FluttraceOverlay FPS estimation metric now correctly calculates using window timestamps instead of max theoretical frames.

1.0.0

• Initial release. Includes:
  • Frame Collector for retrieving frame timing data.
  • Aggregator to compute p50, p95, p99 metrics.
  • Threshold Engine for jank detection.
  • Pluggable transport system (PerfTransport).
  • Real-time performance HUD overlay (FluttraceOverlay).
