undefined is not an object (evaluating '_reactNative.Stylesheet.create')

I am getting is pesky error 'undefined is not an object (evaluating '_reactNative.Stylesheet.create')' as can be seen in the screenshot as well.

Following is the code I am using;

import React, {Component} from 'react';import {Text, Stylesheet} from 'react-native';import {Content, Container, Body, Title} from 'native-base';import GoogleStaticMap from 'react-native-google-static-map';export default class Contact extends Component {  render() {    return (<GoogleStaticMap      style={styles.map}      latitude={'32.064171'}      longitude={'34.7748068'}      zoom={13}      size={{      width: 300,      height: 550    }}    />);  }}const styles = Stylesheet.create({  map: {    width: 300,    height: 550  }});module.export = Contact;
