import React from "react";
import { View, StyleSheet } from "react-native";

export default () => {

    return (
        <View style={styles.root}>
            <View style = {styles.subWView}/>
            <View style = {styles.subWView}/>
            <View style = {styles.subWView}/>
        <View/>
    );
}

const styles = StyleSheet.create({
    root: {
        flexDirection: 'column',
        height: '100%',
        backgroundColor: '#C0C0C0'
    },
    subWView: {
        width: 100,
        height: 100,
        backgroundColor: 'red'
    }
});
