如何在样式表外更改样式表属性？React Native

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

const MyComponent = () => {
  const textStyle = {
    color: 'red',
    fontSize: 16,
    fontWeight: 'bold',
  };

  return (
    <View>
      <Text style={textStyle}>Hello World</Text>
    </View>
  );
};

export default MyComponent;

import React, { useState } from 'react';
import { View, Text, TouchableOpacity } from 'react-native';

const MyComponent = () => {
  const [isHighlighted, setIsHighlighted] = useState(false);

  const textStyle = {
    color: isHighlighted ? 'red' : 'black',
    fontSize: isHighlighted ? 20 : 16,
    fontWeight: isHighlighted ? 'bold' : 'normal',
  };

  return (
    <View>
      <Text style={textStyle}>Hello World</Text>
      <TouchableOpacity onPress={() => setIsHighlighted(!isHighlighted)}>
        <Text>Toggle Highlight</Text>
      </TouchableOpacity>
    </View>
  );
};

export default MyComponent;
