1、项目代码结构

2、页面编写以及路由配置

main.dart(入口文件)

import 'package:flutter/material.dart';
import 'package:flutter_haoke/application.dart';void main() {//启动后去加载application.dart这个文件runApp(const Application());
}

page_content.dart

import 'package:flutter/material.dart';import '../routes.dart';//‌StatelessWidget‌是Flutter框架中的一个基本组件，用于构建不可变的用户界面元素。StatelessWidget的特点是它的状态不会因为用户交互或数据变化而改变，其UI完全由build()方法描述。
//定义和用途:StatelessWidget是Flutter中不需要状态改变的Widget组件，其内部没有需要管理的状态。它主要用于描述那些不会因为外部变化而改变的界面元素，如文本、按钮、图标等静态UI元素‌class PageContent extends StatelessWidget {final String name;const PageContent({Key? key, required this.name}) : super(key: key);@overrideWidget build(BuildContext context) {return Scaffold(appBar: AppBar(title: Text("页面是：$name"),),body: ListView(children: [//FloatingActionButton是一个圆形的浮动操作按钮，通常用于在移动应用中提供一个快速的、突出的操作入口。它不仅外观醒目，而且可以提升用户体验‌FloatingActionButton(//onPressed属性常用于各种按钮控件，如登录按钮、提交按钮、返回按钮等，以响应用户的点击行为onPressed: () {//Navigator.pushNamed方法是用于在路由之间进行页面跳转的方法，它可以接收两个参数：context和routeNameNavigator.pushNamed(context, Routes.home);},child: Text(Routes.home)),FloatingActionButton(onPressed: () {Navigator.pushNamed(context, Routes.login);},child: Text(Routes.login)),FloatingActionButton(onPressed: () {//跳转的页面路径不存在，就走notfoundpage这个请求的处理逻辑Navigator.pushNamed(context, "/aaa");},child: Text("Not")),FloatingActionButton(onPressed: () {Navigator.pushNamed(context, "/room/345");},child: Text("传值")),],),);}
}

index.dart（首页）

import 'package:flutter/material.dart';
import 'package:flutter_haoke/pages/home/tab_index/index.dart';
import 'package:flutter_haoke/pages/home/tab_info/index.dart';
import 'package:flutter_haoke/pages/home/tab_profile/index.dart';
import 'package:flutter_haoke/pages/home/tab_search/index.dart';
//存放各个table页的点击方法
List<Widget> tabViewList = [TabIndex(), TabSearch(), TabInfo(), TabProfile()];List<BottomNavigationBarItem> barItemList = [BottomNavigationBarItem(icon: Icon(Icons.home), label: "首页"),BottomNavigationBarItem(icon: Icon(Icons.search), label: "搜索"),BottomNavigationBarItem(icon: Icon(Icons.info), label: "资讯"),BottomNavigationBarItem(icon: Icon(Icons.account_circle), label: "我的"),
];
//‌StatefulWidget‌是Flutter框架中的一个重要概念，它代表有状态的组件，即其状态可以改变的组件。与StatelessWidget相比，StatefulWidget允许其内部状态发生变化，从而影响组件的显示。
//定义与特点:StatefulWidget的主要特点是其内部状态可以改变。它通过一个独立的State对象来管理其状态，当状态发生变化时，组件的UI也会相应更新。StatefulWidget适用于那些需要根据用户交互或数据变化来更新界面的场景，例如计数器、下拉刷新、上拉加载更多等功能‌class HomePage extends StatefulWidget {const HomePage({Key? key}) : super(key: key);@overrideState<HomePage> createState() => _HomePageState();
}class _HomePageState extends State<HomePage> {int _selectedIndex = 0;void _onTapItem(index) {setState(() {_selectedIndex = index;});}@overrideWidget build(BuildContext context) {return Scaffold(body: tabViewList[_selectedIndex],bottomNavigationBar: BottomNavigationBar(type: BottomNavigationBarType.fixed,items: barItemList,onTap: _onTapItem,currentIndex: _selectedIndex,selectedItemColor: Colors.green,),);}
}

application.dart（启动加载类）

import 'package:fluro/fluro.dart';
import 'package:flutter/material.dart';
import 'package:flutter_haoke/pages/home/index.dart';
import 'package:flutter_haoke/pages/loading.dart';
import 'package:flutter_haoke/routes.dart';
import 'package:flutter_haoke/scopoed_model/auth_model.dart';
import 'package:flutter_haoke/scopoed_model/city.dart';
import 'package:flutter_haoke/scopoed_model/room_filter.dart';
import 'package:scoped_model/scoped_model.dart';class Application extends StatelessWidget {const Application({Key? key}) : super(key: key);@overrideWidget build(BuildContext context) {FluroRouter router = FluroRouter();//读取路由配置类routes.dartRoutes.configureRoutes(router);return ScopedModel<CityModel>(model: CityModel(),child: ScopedModel<AuthModel>(model: AuthModel(),child: ScopedModel<FilterBarModel>(model: FilterBarModel(),child: MaterialApp(theme: ThemeData(primarySwatch: Colors.green),onGenerateRoute: router.generator,// home: HomePage(),initialRoute: Routes.loading,),),));;}
}

pubspec.yaml（依赖配置文件）

依赖配置文件，使用路由等都需要在这个文件中引入依赖。

}

3、Fluro路由

routes.dart（路由配置类）

// 1.编写route文件 并编写routes基本结构
import 'package:fluro/fluro.dart';
import 'package:flutter/material.dart';
import 'package:flutter_haoke/loading.dart';
import 'package:flutter_haoke/pages/community_picker.dart';
import 'package:flutter_haoke/pages/home/index.dart';
import 'package:flutter_haoke/pages/loading.dart';
import 'package:flutter_haoke/pages/login.dart';
import 'package:flutter_haoke/pages/notfound.dart';
import 'package:flutter_haoke/pages/register.dart';
import 'package:flutter_haoke/pages/room_add/index.dart';
import 'package:flutter_haoke/pages/room_manager/index.dart';
import 'package:flutter_haoke/pages/roomdetail/index.dart';
import 'package:flutter_haoke/pages/setting.dart';class Routes {// 2.定义路由名称static String home = '/';static String login = '/login';static String register = '/register';static String roomdetail = '/roomDetail/:roomId';static String setting = '/setting';static String roommanager = '/roommanager';static String roomAdd = '/roomAdd';static String community = '/community';static String loading = '/loading';// 3.定义路由处理函数static Handler _homeHandel = Handler(handlerFunc: (context, parameters) {return HomePage();},);static Handler _loginHandel = Handler(handlerFunc: (context, parameters) {return LoginPage();},);static Handler _registerHandel = Handler(handlerFunc: (context, parameters) {return RegisterPage();},);static Handler _settingHandel = Handler(handlerFunc: (context, parameters) {return SettingPage();},);static Handler _roommanagerHandel = Handler(handlerFunc: (context, parameters) {return RoomManagerPage();},);static Handler _roomdetailHandel = Handler(handlerFunc: (context, parameters) {return RoomDetailPage(roomId: parameters["roomId"]![0],);},);static Handler _notfoundHandel = Handler(handlerFunc: (context, parameters) {return NotFoundPage();},);static Handler _roomAddHandel = Handler(handlerFunc: (context, parameters) {return RoomAddPage();},);static Handler _communityHandel = Handler(handlerFunc: (context, parameters) {return CommunityPickerPage();},);static Handler _loadingHandel = Handler(handlerFunc: (context, parameters) {return LoadingPage();},);// 4.编写函数 configureRoutes 关联路由名称和处理函数static void configureRoutes(FluroRouter router) {router.define(home, handler: _homeHandel);router.define(login, handler: _loginHandel);router.define(register, handler: _registerHandel);router.define(roomdetail, handler: _roomdetailHandel);router.define(setting, handler: _settingHandel);router.define(roommanager, handler: _roommanagerHandel);router.define(roomAdd, handler: _roomAddHandel);router.define(community, handler: _communityHandel);router.define(loading, handler: _loadingHandel);//定义找不到页面时走这个找不到页面的Handelrouter.notFoundHandler = _notfoundHandel;}
}

not_found_page.dart(路由优化，找不到页面时展示此页面)

import 'package:flutter/material.dart';class NotFoundPage extends StatelessWidget {const NotFoundPage({Key? key}) : super(key: key);@overrideWidget build(BuildContext context) {return Scaffold(appBar: AppBar(title: Text("404"),),body: Center(child: Text("页面不存在！"),),);}
}

4、注册页面

import 'package:flutter/material.dart';
import 'package:flutter_haoke/utils/common_toast.dart';
import 'package:flutter_haoke/utils/dio_http.dart';
import 'package:flutter_haoke/utils/string_is_bull_or_empty.dart';class RegisterPage extends StatefulWidget {const RegisterPage({Key? key}) : super(key: key);
//createState是State对象的初始化方法，初始化时执行_RegisterPageState方法@overrideState<RegisterPage> createState() => _RegisterPageState();
}class _RegisterPageState extends State<RegisterPage> {var usernameController = TextEditingController();var passwordController = TextEditingController();var surePsdController = TextEditingController();_onRegisterHandle() async {var username = usernameController.text;var password = passwordController.text;var surePsd = surePsdController.text;if (password != surePsd) {return CommontToast.showToast("两次输入的密码不一致！");}if (StringIsNullOrEmpty(username) || StringIsNullOrEmpty(password)) {return CommontToast.showToast("用户名或密码不能为空！");}const url = "/register";var params = {'username': username, 'password': password};var res = await DioHttp.of(context).post(url, params);
//  {"data":{"code":0,"data":[{"name":"admin","ps":123}],"message":"success"}}if (res.data!["data"]["code"] == 0) {CommontToast.showToast(res.data!["data"]["message"]);Navigator.of(context).pushReplacementNamed("login");}}@overrideWidget build(BuildContext context) {return Scaffold(appBar: AppBar(title: Text("注册"),),body: SafeArea(minimum: EdgeInsets.all(30),child: ListView(children: [TextField(controller: usernameController,decoration: InputDecoration(labelText: "用户名",),),Padding(padding: EdgeInsets.all(10)),TextField(controller: passwordController,obscureText: true,decoration: InputDecoration(labelText: "密码",),),Padding(padding: EdgeInsets.all(10)),TextField(controller: surePsdController,obscureText: true,decoration: InputDecoration(labelText: "确认密码",),),Padding(padding: EdgeInsets.all(10)),ElevatedButton(child: Text("注册"),onPressed: () {_onRegisterHandle();},),Padding(padding: EdgeInsets.all(10)),Row(mainAxisAlignment: MainAxisAlignment.center,children: [Text("已有账号，"),TextButton(onPressed: () {Navigator.pushReplacementNamed(context, "register");},child: Text("去登录~"))],)],),));}
}
