React Native position:"absolute" not working

I am newbie to react-native, I was learning it from youtube but in there the code block used to align the logo-image on top of the screen works, however for me the code didn't work. The exact timestamp of the video is here.

Following is my code:

import React from "react";import { ImageBackground, StyleSheet, View, Image, Text } from "react-native";function WelcomeScreen(){    return (<ImageBackground style={styles.background} ><View styles={styles.logoContainer}><Image styles={styles.logo} source={require('../assets/favicon.png')} /><Text>Don't know why isn't it working</Text></View><View style={styles.loginButton}></View> <View style={styles.registerButton}></View>    </ImageBackground>    );}const styles = StyleSheet.create({    background: {        flex: 1,        justifyContent: "flex-end",        alignItems: "center",        borderColor: "#FF0000",        borderWidth: 2    },    loginButton: {        width: "100%",        height: 60,        backgroundColor: "#FD7E14",        borderColor: "#FF0000",        borderWidth: 2    },    logo: {        width: 200,        height: 200,    },    logoContainer: {        position:"absolute",        top: 70,        alignItems: "center",        borderColor: "#FF0000",        borderWidth: 2    },    registerButton: {        width: "100%",        height: 60,        backgroundColor: "#2196F3",        borderColor: "#FF0000",        borderWidth: 2    },})export default WelcomeScreen;

Here, I am trying to bring logoContainerview on top upper half of the screen but I am not able to get the desired result, please help me with the alignment.
App.js

import WelcomeScreen from "./app/screens/WelcomeScreen"export default function App() {  return (<WelcomeScreen />  );}

Also if possible kindly share references to learn view positioning, because it has become the biggest hurdle for me.
