Expo.DangerZone.DeviceMotion undefined object error

I am having trouble getting the Expo.DangerZone.DeviceMotion class working. I keep getting a
"TypeError: undefined is not an object (evaluating ‘Expo.DangerZone.DeviceOrientation.addListener’)"

Here are my code snippets:

from App.js:

import { DangerZone } from 'expo';
let { DeviceMotion }  = DangerZone;
...
   this._subscriptionO = Expo.DangerZone.DeviceOrientation.addListener((result) => {
      this.setState({orientationData: result});
    });

package.json:

 "dependencies": {
    "expo": "^22.0.0",
    "react": "16.0.0-beta.5",
    "react-native": "https://github.com/expo/react-native/archive/sdk-22.0.1.tar.gz"
  }

I have also tried just importing Expo from ‘expo’ but get a similar result.

I’m overlooking something obvious I’m sure. Anyone can help?

In your code you have Expo.DangerZone.DeviceOrientation but you probably meant to write DeviceMotion. Try that?

Der.

Thanks so much for the kind reply to an obvious error :blush:

That did the trick
