如何在flutter中导航到主屏幕

import 'package:flutter/material.dart';

class HomeScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Home'),
      ),
      body: Center(
        child: Text('Welcome to the Home Screen!'),
      ),
    );
  }
}

import 'package:flutter/material.dart';
import 'package:your_app/home_screen.dart'; // 导入主屏幕页面

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Your App',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: HomeScreen(), // 设置HomeScreen为初始路由
    );
  }
}
