🌀 Gyroscope Module Documentation

Overview

The Gyroscope module provides angular velocity measurements around the device's three axes, enabling rotation detection, orientation tracking, and gesture recognition. Essential for advanced motion analysis and gaming applications.

🎯 Features

• 3-Axis Angular Velocity: X, Y, Z rotation measurement
• Real-time Rotation Data: Continuous gyroscope updates
• Gesture Recognition: Detect rotational gestures and movements
• Device Orientation: Track device orientation changes
• Calibration Support: Auto-calibration and bias correction

📋 Integration Guide

Dependencies

dependencies:
  sensors_plus: ^4.0.2
  flutter_riverpod: ^2.4.9

Basic Implementation

// Entity
class GyroscopeData {
  final double x, y, z;
  final DateTime timestamp;

  const GyroscopeData({required this.x, required this.y, required this.z, required this.timestamp});

  double get magnitude => math.sqrt(x * x + y * y + z * z);
}

// Provider
final gyroscopeProvider = StreamProvider<GyroscopeData>((ref) {
  return gyroscopeEvents.map((event) => GyroscopeData(
    x: event.x, y: event.y, z: event.z, timestamp: DateTime.now()
  ));
});

// Usage
class GyroscopeScreen extends ConsumerWidget {
  @override
  Widget build(BuildContext context, WidgetRef ref) {
    final gyroAsync = ref.watch(gyroscopeProvider);

    return gyroAsync.when(
      data: (data) => Column(children: [
        Text('X: ${data.x.toStringAsFixed(2)}'),
        Text('Y: ${data.y.toStringAsFixed(2)}'),
        Text('Z: ${data.z.toStringAsFixed(2)}'),
      ]),
      loading: () => CircularProgressIndicator(),
      error: (e, _) => Text('Error: $e'),
    );
  }
}

🔧 Use Cases
