Style once, use everywhere. A build system for creating cross-platform styles.

import { registerRootComponent } from 'expo';

import App from './src/App';

// registerRootComponent calls AppRegistry.registerComponent('main', () => App);
// It also ensures that whether you load the app in the Expo client or in a native build,
// the environment is set up appropriately
registerRootComponent(App);
