React Native Practical - Interview Questions and Answers

The platform module detects the platform in which the app is running.

import { Platform, Stylesheet } from 'react-native';
const styles = Stylesheet.create({
height: Platform.OS === 'IOS' ? 200 : 400
})?

Additionally Platform.select method available that takes an object containing Platform.OS as keys and returns the value for the platform you are currently on.

import { Platform, StyleSheet } from 'react-native';
const styles = StyleSheet.create({
 container: {
flex: 1,
   ...Platform.select({
     ios: {
       backgroundColor: 'red',
     },
     android: {
       backgroundColor: 'green',
     },
     default: {
       // other platforms, web for example
       backgroundColor: 'blue',
     },    }),
},
});?
