How to save the QR Data and copy my clipboard? - reactjs

Question

I just have some question.
First, I'm beginner... Very sorry.
I have been developed the react-native app (iOS) for recognize the QR Code.
I already have been succeed the recognize the QR Code on my App.
But My Plan is..
First, I scan the QR Code and I want to save the QR data.
For the purpose, there are many QR Code in the warehouse above many box and it is included Serial Number.
After scanning, I will continue the scan until I want to stop it. (In conclusion, I scan many times.)
I just thought "Let's save the Serial Number at array.
Second, I save the serial number through the scanning and I want to copy our clipboard.
Also, I want to print in my App.
How can I implement this? I have no idea about that.
Code is here.
import { StatusBar } from 'expo-status-bar';
import React, {useState, useEffect} from 'react'
import { StyleSheet, Text, View, Button } from 'react-native';
import { BarCodeScanner } from 'expo-barcode-scanner';
export default function App() {
const [hasPermisson, setHasPermisson] = useState(null);
const [scanned, setScanned] = useState(false);
const [text, setText] = useState('Not yet scanned')
const askForCameraPermisson = () => {
(async () => {
const {status} = await BarCodeScanner.requestPermissionsAsync();
setHasPermisson(status == 'granted')
})()
}
useEffect(() => {
askForCameraPermisson ();
}, [])
const handleBarCodeScanned = ({type, data}) => {
setScanned(true);
setText(text);
state = {
sn : [
{
type : type,
data : data
},
{
type : type,
data : data
}
]
}
console.log(state)
}
if (hasPermisson === null) {
return (
<View style={styles.container}>
<Text>Requesting for camera permisson</Text>
<StatusBar style="auto" />
</View>
)
}
if(hasPermisson === false) {
return (
<View style={styles.container}>
<Text>No acess to camera</Text>
<Button title={'Allow Camera'} onPress={() => askForCameraPermisson()}/>
</View>
)
}
return (
<View style={styles.container}>
<View style={styles.barcodebox}>
<BarCodeScanner
onBarCodeScanned={scanned ? undefined : handleBarCodeScanned}
style = {{ height:400, width:400}} />
</View>
<Text style={styles.maintext}>{text}</Text>
{scanned && <Button title={'scan again?'} onPress={( ) => setScanned(false)} color='tomato'/>}
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#fff',
alignItems: 'center',
justifyContent: 'center',
},
barcodebox: {
alignItems: 'center',
justifyContent: 'center',
height: 300,
width:300,
overflow:'hidden',
borderRadius:30,
backgroundColor:'tomato'
},
maintext: {
fontSize :16,
margin:20
}
});
