Eye Tracking Proctor for Flutter (community fork) #

A maintained fork of eye_tracking (MIT-licensed) adapted for anti-cheating / remote-proctoring use cases.
This fork adds attention/screen state signals, stable gaze confidence, real calibration accuracy, warm-up gating, and ready-to-use signals for remote proctoring.

✨ What’s new #

• 📡 Lifecycle & state stream
  • New getStateStream()
  • emits initializing → ready → warmingUp → tracking / paused / calibrating / error
  • flips to tracking only after the first valid gaze sample.
• 👁️ Attention-aware confidence
  • Computes confidence per frame using page Attention gate + focus, Viewport bounds, and frame freshness.
  • Let you build per-tick metrics (off-screen time, face-missing time, look-away time, copy/paste events) and compute a proctoring score for anti-cheating scenarios.
• 🎯 Real calibration accuracy
  • Train + eval around each point
  • Calibration Accuracy is normalized by viewport diagonal.
• ⚙️ Config & extensibility
  • New setTracker, setRegression, addTrackerModule, and addRegressionModule.
• ⚡ Startup polish
  • Simplified auto-calibration (center point) for quicker boot.
  • Silent pre-warm so first “Start” is smooth (no UI jank)
