API Reference

Core Class: VitureKit

Method / Property	Type	Description
sdkVersion	String	Returns the native SDK version string.
isHeadTrackingActive	bool	Indicates whether IMU data is currently streaming.
poseStream	Stream<ViturePoseData>	Broadcast stream delivering raw and parsed orientation updates.
getBrightnessLevel()	int	Reads the current brightness level from the connected device.
setBrightnessLevel(int level)	void	Sets the brightness level for the connected device.
getVolumeLevel()	int	Reads the current volume level from the connected device.
setVolumeLevel(int level)	void	Sets the volume level for the connected device.
takeHeadTracking({int productId})	Future<void>	Initializes native bindings and starts receiving IMU data.
releaseHeadTracking()	Future<void>	Safely shuts down the native provider and terminates the worker isolate.
setHeadTrackingEnabled(bool enabled)	Future<void>	Convenience toggle for starting or stopping head tracking.
dispose()	Future<void>	Releases tracking and closes the pose controller.

Data Models & Constants

ViturePoseData

Holds orientation and timestamp attributes:

• roll, pitch, yaw: double (Euler angles)
• quatW, quatX, quatY, quatZ: double (Quaternion orientation)
• timestamp: int

Usage Example

import 'dart:async';
import 'package:viture_kit/viture_kit.dart';

Future<void> main() async {
  final viture = VitureKit();

  print('VITURE SDK Version: ${VitureKit.sdkVersion}');

  // 1. Listen to orientation events
  final subscription = viture.poseStream.listen((ViturePoseData pose) {
    print('Roll: ${pose.roll}, Pitch: ${pose.pitch}, Yaw:${pose.yaw}');
    print('Quat: [${pose.quatW},${pose.quatX}, ${pose.quatY},${pose.quatZ}]');
  });

  // 2. Claim ownership of the IMU
  try {
    await viture.takeHeadTracking();
    print('Head tracking started successfully.');
  } catch (e) {
    print('Failed to start head tracking: $e');
  }

  // 3. Stop tracking and clean up
  await subscription.cancel();
  await viture.releaseHeadTracking();
  await viture.dispose();
  print('Head tracking released.');
}

Caveat

Important

When the Spacewalker App is open VitureKit will assume control of the IMU for head tracking, stopping tracking on the Spacewalker app.
