I want to go to the homepage after splash screen. but I am getting the error

 ERROR    TypeError: undefined is not an object (evaluating '_this.props.navigation.navigate')

My splash screen code is :

import React, {Component} from 'react';
import {View, StyleSheet, ImageBackground, Image} from 'react-native';


var logo=require('./sg.png');
export default class Splash extends Component
{
        constructor(props)
        {
            super(props);
            setTimeout(()=>
            {
                this.props.navigation.navigate('home');
            }, 3000);

        }
        render()
        {
        return(
            <ImageBackground
                style={{backgroundColor: '#F8BBD0', height:'100%', width:'100%'}}>
                <View
                style={{flex:1, justifyContent:'center', alignItems:'center'}}>
                    <Image source={logo}
                    style={{height:300, width:300}}></Image>
                </View>
            </ImageBackground>

        );
    }
}

and my app.js is :

> import React,{Component} from 'react';
> 
> import {createAppContainer} from 'react-navigation'; import
> {createStackNavigator} from 'react-navigation-stack';
> 
> import splash from './splash'; import home from './home_screen';

>     home : {screen:home, navigationOptions:{header:null}},
>     sign : {screen:sign, navigationOptions:{header:null}},
>        } ); export default createAppContainer(App);

and my home screen is

>
