I'm trying to add the router-flux into my project. But getting all the time the error below

Version

• react-native-router-flux v4.0.0-beta.23
• react-native v0.49.5

My Code

`

import React, {Component} from 'react';
import {
StyleSheet,
Text,
View,
ActivityIndicator,
ListView,
Button,
Image,
TouchableOpacity,
} from 'react-native';

import {
Router,Scene
} from 'react-native-router-flux';

import Splash from './components/Splash';
import LoginScreen from './components/LoginScreen';
import NewsListScreen from './components/NewsListScreen';

export default class Main extends Component {

constructor(props) {
    super(props);

}

render() {

    return (
      <Router>
      <Scene key="root">

      <Scene>
        key="loginscreen"
        component={LoginScreen}
        title="Login"
        initial={true}
        </Scene>
        </Scene>
      </Router>
      );
}

}

const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: 'red',
},
});

`
