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});overrideStateStatefulWidget createState() _HomeState();
}class _HomeState extends StateHome {// 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;});},),);}
