将动态变量插入React Native样式表

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

const App = () => {
  const [isActive, setIsActive] = useState(false);

  // 动态变量
  const dynamicStyle = {
    fontSize: isActive ? 20 : 12,
    color: isActive ? 'red' : 'blue',
    backgroundColor: isActive ? 'yellow' : 'white',
  };

  return (
    <View style={styles.container}>
      <Text style={[styles.text, dynamicStyle]}>Hello, World!</Text>
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
  text: {
    fontSize: 12,
    color: 'blue',
    backgroundColor: 'white',
  },
});

export default App;
