如何将道具“OnChangeText”上的TextInput的val转换为int。React Native

import React, { useState } from 'react';
import { TextInput } from 'react-native';

const ExampleComponent = () => {
  const [val, setVal] = useState('');

  const handleChangeText = (text) => {
    const intValue = parseInt(text);
    setVal(intValue.toString());
  };

  return (
    <TextInput
      onChangeText={handleChangeText}
      value={val}
    />
  );
};

export default ExampleComponent;
