如何衡量我的React Native应用使用的总时间

import { AppRegistry } from 'react-native';
import App from './App';
import { name as appName } from './app.json';

const startTime = Date.now();

AppRegistry.registerComponent(appName, () => {
  const endTime = Date.now();
  console.log(`启动时间: ${endTime - startTime} ms`);
  return App;
});

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

const App = () => {
  useEffect(() => {
    const startTime = Date.now();
    const handlePress = () => {
      const endTime = Date.now();
      console.log(`按钮点击时间: ${endTime - startTime} ms`);
    };
    return () => {};
  }, []);

  return (
    <View>
      <Button title="点击" onPress={handlePress} />
    </View>
  );
};

export default App;
