NSMotionUsageDescription (also known as ios.permission.MOTION)

Then register the event listener, you can add a listener for onStartMotion and onStopMotion:

import {
  DeviceEventEmitter,
} from 'react-native';

const onMotionDetected = async () => {
  // Do something when motion is detected
};
DeviceEventEmitter.addListener('onStartMotion', onMotionDetected);

Then import the package and use it like this:

import {
  startActivityRecognition,
  MotionConstants,
} from 'expo-motion-detector';

startActivityRecognition(MotionConstants.Android.WALKING).then((result) => {
    console.log(result);
  }
);
