7.docker运行redis容器

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.
  @override
  Widget 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});

  @override
  State<StatefulWidget> createState() => _HomeState();
}

class _HomeState extends State<Home> {
  // tabbar
  var tabIndex = 0;

  // 页面组件
  var pageList = [HomePage(), SearchPage(), CarPage(), MyPage()];

  @override
  Widget 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),

          ],

        ],
        type: BottomNavigationBarType.fixed,
        currentIndex: tabIndex,
        // backgroundColor: Colors.blue,
