如何从react native中的主题文件夹导入可重用组件？

import React from 'react';
import { StyleSheet, TouchableOpacity, Text } from 'react-native';
import { colors } from '../themes/theme';

const Button = ({ title }) => {
  return (
    <TouchableOpacity style={styles.button}>
      <Text style={styles.buttonText}>{title}</Text>
    </TouchableOpacity>
  );
};

const styles = StyleSheet.create({
  button: {
    backgroundColor: colors.primary,
    padding: 10,
    borderRadius: 5,
  },
  buttonText: {
    color: colors.white,
    fontSize: 16,
    fontWeight: 'bold',
  },
});

export default Button;

import React from 'react';
import { View } from 'react-native';
import Button from './Button';
import { colors } from '../themes/theme';

const App = () => {
  return (
    <View>
      <Button title="Click me" />
    </View>
  );
};

export default App;

export const colors = {
  primary: '#007bff',
  white: '#ffffff',
};
