How to apply styles using styleSheet in react native expo

Question

I am trying to apply some styles in my react native application but it's not working with me, I tried to run it in the browser this is the output showed up:

But when I run it in my phone it's showing me an error:

This is the main App.js file:

import { StatusBar } from 'expo-status-bar';
import React from 'react';
import { View } from 'react-native';
import HomeMenu from './src/screens/Home/index';

export default function App() {
  return (

    <View style={{ flex: 1 }}>
      <StatusBar style="auto" />
      <HomeMenu />
    </View>

  );
}

And this is index.js file (the one I want to show its results):

import React from 'react';
import { View, Text, StyleSheet, SafeAreaView } from 'react-native';

const HomeMenu = () => {
    return (
        <SafeAreaView style={{ flex: 1 }}>   //add flex:1 here
            <View style={styles.container}>
                <Text>Open up App.js to start working on your app!</Text>
            </View>
        </SafeAreaView>
    );
};
export default HomeMenu;

const styles = StyleSheet.create({
    container: {
        flex: 3,
        backgroundColor: '#21534A',
        alignItems: 'center',
        justifyContent: 'center',
    },
});

try like this:-

import React from 'react';
import { View, Text, StyleSheet, SafeAreaView } from 'react-native';

const HomeMenu = () => {
return (
    <SafeAreaView style={{ flex: 1 }}>  
  //add flex:1 here
        <View style={styles.container}>
            <Text>Open up App.js to start working on your app!</Text>
        </View>
    </SafeAreaView>
);
 };
 export default HomeMenu;

const styles = StyleSheet.create({
container: {
    flex: 3,
    backgroundColor: '#21534A',
    alignItems: 'center',
    justifyContent: 'center',
},
});
