            <WebView

                        {
                            props: {
                                backgroundColor: '#ffffff',
                                flex: 1,
                            }
                        }

                  onMessage={this.onMessage}
                  onNavigationStateChange={(e)=>this.onNavigationStateChange(e)}
                  />
        </ScrollView>

I used in this way

import UAParser from 'ua-parser-js'
import UserAgent from 'react-native-user-agent'

const userAgent = UserAgent.getUserAgent()
const parser = new UAParser(userAgent).getResult()

const {device, os, browser} = parser
const {type, vendor, model} = device
const {name, version} = os
const {name, major} = browser

I used in this way. This is working good for me
