关于flutter:flutter-fluro-优化路由配置

问题：
谬误页面如何解决？带参数的页面如何解决？
步骤：
1、谬误页面解决

①在/page目录增加not_found.dart    ②实现NotFoundPage    ③在router.dart增加_notFoundHandler  ④在router.dart的configureRoutes中增加router.notFoundHandler=_notFoundHandler  ⑤批改PageContent测试  

2、带参数的页面解决

①在/page目录增加room_detail/index.dart  ②实现RoomDetailPage    ③在router.dart增加_RoomDetailHandler  ④在router.dart的configureRoutes中增加router.RoomDetailHandler=_RoomDetailHandler  ⑤批改PageContent测试  

not_found.dart

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

room_detail/index.dart

import 'package:flutter/material.dart';class RoomDetailPage extends StatelessWidget {  final String roomId;  const RoomDetailPage({Key key, this.roomId}) : super(key: key);  @override  Widget build(BuildContext context) {    return Scaffold(      appBar: AppBar(title: Text('roomId: $roomId'),),    );  }}

router.dart

import 'package:fluro/fluro.dart';import 'package:flutter/material.dart';import './pages/room_detail/index.dart';import './pages/not_found.dart';import './pages/home/index.dart';import './pages/login.dart';class Routes {  //1、定义路由名称  static String home = '/';  static String login = '/login';  static String roomdetail = '/room/:roomId';  //2、定义路由处理函数  static Handler _homeHandler = Handler(handlerFunc: (BuildContext context, Map<String, dynamic> params) {    return HomePage();  });  static Handler _loginHandler = Handler(handlerFunc: (BuildContext context, Map<String, dynamic> params) {    return LoginPage();  });  static Handler _roomDetailHandler = Handler(handlerFunc: (BuildContext context, Map<String, dynamic> params) {    return RoomDetailPage(roomId: params['roomId'][0],);  });  static Handler _NotFoundHandler = Handler(handlerFunc: (BuildContext context, Map<String, dynamic> params) {    return NotFoundPage();  });  //3、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: _homeHandler);    router.define(login, handler: _loginHandler);    router.define(roomdetail, handler: _roomDetailHandler);    router.notFoundHandler = _NotFoundHandler;  }}

成果如下：
