react-native-device-rotation

Get updates about a phones attitude in three axis. Values are in degrees and are roll, pitch and azimuth. Works for android and iOS. From my testing the differences are: pitch degrees are flipped for android and iOS, north (azimuth = 0) is the top of the phone in android and the right og the phone in iOS.

TODOS:

  • it's an early version of the package, so theres room for improvements
  • make sure values are the same on ios and android
  • method to check availability of the sensors

Getting started

yarn add react-native-device-rotation

import RNDeviceRotation from 'react-native-device-rotation';
 
componentDidMount() {
        // only does stuff in iOS currently
        RNDeviceRotation.setUpdateInterval(0.2)
 
        const orientationEvent = new NativeEventEmitter(RNDeviceRotation)
        this.subscription = orientationEvent.addListener('DeviceRotation', event => {
            log('DeviceRotation', event)
            this.setState({
                roll: event.roll,
                pitch: event.pitch,
                azimuth: event.azimuth,
            })
        })
        RNDeviceRotation.start()
    }
 
    componentWillUnmount() {
        if (this.subscription) {
            this.subscription.remove()
