   compile project(':react-native-appstore-version-checker')
import {getAppstoreAppVersion} from 'react-native-appstore-version-checker';
or
var getAppstoreAppVersion = require('react-native-appstore-version-checker').getAppstoreAppVersion;
//On Android u can do
getAppstoreAppVersion('com.supercell.clashofclans') //put any apps packageId here
.then((appVersion) => {
  console.log('clashofclans android app version on playstore', appVersion);
})
.catch((err) => {
  console.log('error occurred', err);
});
//On IOS u can do

});Finding appid for an ios app
Search for an app on itunes store. Lets take the example of clash of clans.
The area marked on red is the app's appid
Finding packageId for an android app
Search for an app on playstore. Lets take the example of clash of clans.
The area marked on red is the app's packageId
getAppstoreAppVersion(identifier, options);params:
- 
identifieris the app package id likecom.example.app
- 
optionscontains values which can affect the result obtained from the store- 
jquerySelector[Android] is the dom element identifier (much like jquery selector) for playstore app page. Currently to get the appversion from the page we do loadhttps://play.google.com/store/apps/details?id=<app package id>and parse$('body > [itemprop="softwareVersion"]')but you can optionally pass in a custom selector if you want. This is useful if dom structure of the app store page changes in the future.
- 
typeOfId[iOS] (default isid) It can be eitheridorbundleId. If thetypeOfIdisidyou need to passidentifieras appid and iftypeOfIdisbundleIdyou need to pass bundleIdentifier toidentifier. It is basically, the query parameter forhttps://itunes.apple.com/lookup?${typeOfId}=${identifier}. Currently to get the ios version number from app store we hit the urlhttps://itunes.apple.com/lookup?id=<app id>by default. or we can also hithttps://itunes.apple.com/lookup?bundleId=<app bundle id>if we pass typeOfId asbundleId. When we hit the above said urls we get json with all the info of the app.
- 
country[iOS] (default isus) The two-letter country code for the store you want to search. The search uses the default store front for the specified country.

Example
const storeSpecificId = Platform.OS === 'ios'
    ? '529479190'
    : 'com.supercell.clashofclans'
getAppstoreAppVersion(storeSpecificId, {
    jquerySelector: '[itemprop=\'softwareVersion\']',
    typeOfId: 'id',
    country: 'de'
