flutter自带的scaffold脚手架可以说还是挺好用的，集成了appBar，还有左侧抽屉，还有底部tabbar，可以说拿来就可以用了啊，所以我今天也体验了一下，做了一个最简单的demo，就当是学习记录了。

效果展示：

基础的项目目录： 

pages里面存放的是每个页面的页面代码，然后在main.dart中将四个页面引入

然后再开始配置scaffold脚手架：一下是项目的完成代码

import 'package:flutter/material.dart';
import 'package:flutter_app/pages/car.dart';
import 'package:flutter_app/pages/search.dart';
import 'package:flutter_app/pages/home.dart';
import 'package:flutter_app/pages/my.dart';
import 'package:get/get.dart';void main() {runApp(const MyApp());
}class MyApp extends StatelessWidget {const MyApp({super.key});// This widget is the root of your application.@overrideWidget build(BuildContext context) {// 返回素材组件return GetMaterialApp(title: 'Flutter Demo',theme: ThemeData(primaryColor: Colors.deepPurple),// 其实要返回一个对象的，但是在flutter中，new可以省略，所以const MyHomePage()home: const Home(),);}
}// 创建一个有状态的组件
class Home extends StatefulWidget {const Home({super.key});@overrideState<StatefulWidget> createState() => _HomeState();
}class _HomeState extends State<Home> {// tabbarvar tabIndex = 0;// 页面组件var pageList = [HomePage(), SearchPage(), CarPage(), MyPage()];@overrideWidget build(BuildContext context) {return Scaffold(appBar: AppBar(title: const Text("电影频道"),centerTitle: true,backgroundColor: Colors.blue,),drawer: Drawer(child: ListView(children: [UserAccountsDrawerHeader(accountEmail: Text('wo shi Email'),accountName: Text('我是Drawer'),currentAccountPicture: CircleAvatar(backgroundImage: AssetImage('images/avatar.jpg'),),),ListTile(title: Text("淘宝购物"),leading: Icon(Icons.shop),trailing: Icon(Icons.legend_toggle),),ListTile(title: Text("拼多多商城"),leading: Icon(Icons.piano),trailing: Icon(Icons.legend_toggle),),ListTile(title: Text("京东优选"),leading: Icon(Icons.generating_tokens_sharp),trailing: Icon(Icons.legend_toggle),),ListTile(title: Text("随便买买"),leading: Icon(Icons.home),trailing: Icon(Icons.legend_toggle),),],),),body: pageList[tabIndex],bottomNavigationBar: BottomNavigationBar(items: [BottomNavigationBarItem(icon: Icon(Icons.home), label: "首页"),BottomNavigationBarItem(icon: Icon(Icons.search), label: "搜索"),BottomNavigationBarItem(icon: Icon(Icons.category_rounded), label: "购物车"),BottomNavigationBarItem(icon: Icon(Icons.supervised_user_circle), label: "我的"),],type: BottomNavigationBarType.fixed,currentIndex: tabIndex,// backgroundColor: Colors.blue,showUnselectedLabels: true,unselectedItemColor: Colors.grey,unselectedLabelStyle: TextStyle(color: Colors.grey),selectedItemColor: Colors.blue,selectedLabelStyle: TextStyle(color: Colors.blue),onTap: (index) {print(index);setState(() {tabIndex = index;});},),);}
