Methods#

select()#

static select(config: object): any

Returns the most fitting value for the platform you are currently running on.

Parameters:#

NameTypeRequiredDescription
configobjectYesSee config description below.

Select method returns the most fitting value for the platform you are currently running on. That is, if you're running on a phone, android and ios keys will take preference. If those are not specified, native key will be used and then the default key.

The config parameter is an object with the following keys:

  • android (any)
  • ios (any)
  • native (any)
  • default (any)

Example usage:

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

This will result in a container having flex: 1 on all platforms, a green background color on Android, a red background color on iOS, and a blue background color on other platforms.

Since the value of the corresponding platform key can be of type any, select method can also be used to return platform-specific components, like below:

const Component = Platform.select({  ios: () => require('ComponentIOS'),  android: () => require('ComponentAndroid')})();
<Component />;
const Component = Platform.select({  native: () => require('ComponentForNative'),  default: () => require('ComponentForWeb')})();
<Component />;
