import React, { Component } from 'react';
import { View, ImageBackground, StyleSheet, BackHandler, Alert } from 'react-native';
import { Actions } from 'react-native-router-flux';
import colors from '../styles/colors';

class SplashScreen extends Component {

    componentDidMount() {
        // Start counting when the page is loaded
        this.timeoutHandle = setTimeout(() => {
            Actions.welcome()
        }, 5000);
    }

    render() {
        return (
            <View style={styles.container}>
                <ImageBackground
                    source={require('../assets/BSWH-splash.jpg')}
                    style={styles.backgroundImage}
                />
            </View>
        );
    }

const styles = StyleSheet.create({
    container: {
        flex: 1,
    },
    backgroundImage: {
        resizeMode: 'stretch',
        flex: 1,

    logoText: {
        fontSize: 34,
        color: colors.white,
        margin: 10,
