Example

import React, { useState } from 'react';
import {
  SafeAreaView,
  StyleSheet,
  TextInput,
  View,
} from 'react-native';
import QRCode from 'react-native-qrcode-svg';

const App = () => {
  const [url, setUrl] = useState('');

  const handleTextChange = (text) => {
    setUrl(text);
  };

  return (
    <SafeAreaView style={styles.container}>
      <View style={styles.inputContainer}>
        <TextInput
          style={styles.input}
          placeholder="Enter URL"
          onChangeText={handleTextChange}
          value={url}
        />
      </View>
      {url ? (
        <View style={styles.qrCodeContainer}>
          <QRCode
            value={url}
            size={200}
            color="black"
