GazePoint SDK for Flutter

Cross-platform Flutter plugin for eye tracking and gaze point detection on Android and iOS.

Repository: Tareq-Ghassan/GazePointSDK-Flutter
Package: gazepoint_sdk

Native gaze math is vendored inside this plugin (Android Kotlin + iOS Swift), so the package is self-contained for pub.dev. Standalone native SDKs remain in:

• GazePointSDK-Android
• GazePointSDK-iOS

Installation

dependencies:
  gazepoint_sdk: ^2.1.0

flutter pub get

Android

• Min SDK 24
• Camera permission is declared by the plugin; request it at runtime via requestCameraPermission()

iOS

• Deployment target iOS 16.0+
• Add to Info.plist:

<key>NSCameraUsageDescription</key>
<string>Camera access is required for eye tracking</string>

Quick start

import 'package:gazepoint_sdk/gazepoint_sdk.dart';

final tracker = GazeTracker();

await tracker.initialize();
if (await tracker.requestCameraPermission()) {
  await tracker.startTracking();
  tracker.gazeStream.listen((result) {
    print('Gaze: ${result.gazePoint}  confidence: ${result.confidence}');
  });
}

Calibration

await tracker.calibrate([
  GazeCalibrationPoint(
    expected: Offset(100, 100),
    actual: latestGaze.gazePoint,
  ),
  // …at least 3 points
]);

Example app

See the umbrella monorepo flutter_example:

cd flutter_example
flutter pub get
flutter run   # physical device; camera required
