Screen orientation - React Native

In React Native, multiple screen orientations are enabled by default. Locking screen orientation is handled in native code:

• For Android, remove instances of the android:screenOrientation attribute.
• For iOS, check if 4 orientations have been added to UISupportedInterfaceOrientations.

You can use the Dimensions API to listen to orientation changes.

Dimensions.addEventListener('change', () => {
    this.setState({
        orientation: Platform.isPortrait() ? 'portrait' : 'landscape'
    });
});
