在flutter中实现textStyle和颜色的完美方式是什么？

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      theme: ThemeData(
        primaryColor: Colors.blue, // 设置主要颜色为蓝色
        accentColor: Colors.red, // 设置强调颜色为红色
        textTheme: TextTheme(
          headline1: TextStyle(fontSize: 24, fontWeight: FontWeight.bold), // 标题样式
          bodyText1: TextStyle(fontSize: 16, color: Colors.black), // 正文样式
        ),
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter Demo'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Text(
              'Hello',
              style: Theme.of(context).textTheme.headline1, // 使用标题样式
            ),
            Text(
              'World',
              style: Theme.of(context).textTheme.bodyText1, // 使用正文样式
            ),
          ],
        ),
      ),
    );
  }
}
