			1. 跳转页面，不传参：
			Routes.navigateTo(
			        context,
			        Routes.setting,
			      );
		1、pop返回页面：
		Navigator.of(context).pop();
		2、返回到/根页面：
		Navigator.of(context).popUntil(ModalRoute.withName('/'));
		Navigator.of(context).popUntil((r) => r.settings.isInitialRoute);
		
		、返回到路由列表中的某个页面：
		Navigator.of(context).popUntil(ModalRoute.withName('/test'));
		
		1main.dart中配置
		void main() {
		  final router = Router();
		  Routes.configureRoutes(router);
		  Routes.router = router;
		  runApp(MyApp());
		}
		...
		...
		return MaterialApp(
		      title: 'Flutter APP',
		      onGenerateRoute: Routes.router.generator, // 配置route generate
		    );

创建Routes.dart

	// 配置路径Route
	import 'package:flutter/material.dart';
	import 'package:fluro/fluro.dart';
	import 'package:***/route/route_handlers.dart';
	
	class Routes {
	  // 路由管理
	  static Router router;
	
	  static String root = '/'; // 根目录
	  static String setting = '/setting'; // 设置页
	  static String webView = '/webView'; // 网页加载
	  static String wxSharePay = '/wxSharePay'; // 测试model传参
	
	  // 配置route
	  static void configureRoutes(Router router) {
	    // 未发现对应route
	    router.notFoundHandler = Handler(handlerFunc: (BuildContext context, Map<String, dynamic> params) {
	      print('route not found!');
	      return;
	    });
	
	    router.define(root, handler: rootHandler); // 根目录
	    router.define(setting, handler: settingHandler); // 设置
	    router.define(webView, handler: webViewHandler); // 网页加载
	    router.define(wxSharePay, handler: wxSharePayHandler); // 测试model传参
	  }
	
	  // 对参数进行encode，解决参数中有特殊字符，影响fluro路由匹配
	  static Future navigateTo(BuildContext context, String path, {Map<String, dynamic> params, TransitionType transition = TransitionType.native}) {
	    String query =  "";
	    if (params != null) {
	      int index = 0;
	      for (var key in params.keys) {
	        var value = Uri.encodeComponent(params[key]);
	        if (index == 0) {
	          query = "?";
	        } else {
	          query = query + "\&";
	        }
	        query += "$key=$value";
	        index++;
	      }
	    }
	    print('我是navigateTo传递的参数：$query');
	
	    path = path + query;
	    return router.navigateTo(context, path, transition:transition);
	  }
	}
