πŸ“² React Native Device Display

This package is now deprecated and I am not actively maintaining it. In the meantime you can also use react-native-orientation.

A simple way to create dynamic views through device, display and orientation detection, allowing the creation of adaptable and universal apps. Currently only for React Native iOS, Android support in progress.

Installation (iOS)

Simply install the package as shown below...

$ npm install react-native-device-display

Next you need to import the DisplayDeviceUtil classes into your project, these come bundled inside the NPM package.
