react-native-orientation-tracker

The React Native Orientation Tracker is a package that allows you to get information on wether a device is in landscape or portrait mode without the need of bridging to native.

How to Use

1. npm install react-native-orientation-tracker -s
2. go to your main index file (index.ios.js/index.android.js/app.js) and import the package:

import orientationTracker from 'react-native-orientation-tracker';

3. Attach orientationTracker.layoutChange on to the onLayout prop to a top level view in the index file

   render() {
          return(
              <View onLayout={orientationTracker.layoutChange}>
                <Text>Some component here</Text>
              </View>
          )
      }

4. Get the current orientation anywhere in the app by accessing

orientationTracker.orientation
