使用fluro時，對引數進行URLEncode來解決找不到路由的問題

一、使用方法

1、route_handlers.dart中新建對應頁面的Handler
2、routes.dart中定義對應的路由

二、跳轉頁面

1. 跳轉頁面，不傳參：

Routes.navigateTo(
        context,
        Routes.setting,
      );

2. 跳轉頁面，傳遞字串引數：

      String title = '我是標題哈哈哈';
      String url = 'https://www.baidu.com/';
      Routes.navigateTo(
        context,
        Routes.webView,
        params: {
          'title': title,
          'url': url,
        },
      );
 

3. 跳轉頁面，傳遞model引數或字串引數：

UserInfoModel userInfoModel =
          UserInfoModel('袁致營', 30, 1.78, 74.0);
      UserInfoModel userInfoModel2 =
      UserInfoModel('袁致營2', 32, 1.78, 74.0);
      String jsonString = convert.jsonEncode(userInfoModel);
      String jsonString2 = convert.jsonEncode(userInfoModel2);

      Routes.navigateTo(
        context,
        Routes.wxSharePay,
        params: {
          'userInfoModel': jsonString,
          'userInfoModel2': jsonString2,
        },
      ).then((result) {
        // 通過pop回傳的值，邊緣策劃返回則不努力通過此處傳值

      });
 

三、返回頁面

1、pop返回頁面：

Navigator.of(context).pop();

2、返回到/根頁面：

Navigator.of(context).popUntil(ModalRoute.withName('/'));

或

Navigator.of(context).popUntil((r) => r.settings.isInitialRoute);

3、返回到路由列表中的某個頁面：

Navigator.of(context).popUntil(ModalRoute.withName('/test'));

或返回fluro中設定的route：

Navigator.of(context).popUntil(ModalRoute.withName(Routes.setting));
 

fluro使用方法

1. main.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
    );

建立Routes.dart

// 配置路徑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 = '/'; // 根目錄
  static String setting = '/setting'; // 設定頁
  static String webView = '/webView'; // 網頁載入
  static String wxSharePay = '/wxSharePay'; // 測試model傳參

  // 配置route
  static void configureRoutes(Router router) {
    // 未發現對應route
    router.notFoundHandler = Handler(handlerFunc: (BuildContext context, Map<String, dynamic> params) {
      print('route not found!');
      return;
    });

    router.define(root, handler: rootHandler); // 根目錄
    router.define(setting, handler: settingHandler); // 設定
    router.define(webView, handler: webViewHandler); // 網頁載入
    router.define(wxSharePay, handler: wxSharePayHandler); // 測試model傳參
  }

  // 對引數進行encode，解決引數中有特殊字元，影響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傳遞的引數：$query');

    path = path + query;
    return router.navigateTo(context, path, transition:transition);
  }
}

建立route_handler.dart

import 'package:fluro/fluro.dart';
import 'package:flutter/material.dart';
import 'dart:convert' as convert;

import 'package:***/common/home.dart';
import 'package:***/widgets/mine/settings.dart';
import 'package:***/common/webview_url.dart';
import 'package:***/widgets/login/wx_share_pay.dart';
import 'package:***/widgets/login/model/user_info_model.dart';

// 根目錄
var rootHandler =
    Handler(handlerFunc: (BuildContext context, Map<String, dynamic> params) {
  return HomePage();
});

// 設定頁 - 示例：不傳引數
var settingHandler =
    Handler(handlerFunc: (BuildContext context, Map<String, dynamic> params) {
  return Settings();
});

// 網頁載入 - 示例：傳多個字串引數
var webViewHandler =
    Handler(handlerFunc: (BuildContext context, Map<String, dynamic> params) {
  // params內容為  {title: [我是標題哈哈哈], url: [https://www.baidu.com/]}
  String title = params['title']?.first;
  String url = params['url']?.first;
  return WebViewUrlPage(
    title: title,
    url: url,
  );
});

// 示例：傳多個model引數
var wxSharePayHandler =
    Handler(handlerFunc: (BuildContext context, Map<String, dynamic> params) {
//  print('params: $params');
//  String model = params['userInfoModel']?.first;
//  print('model: $model');
//  // model: {name: yuanzhiying, age: 30, height: 1.78, weight: 74.0}
//  Map<String, dynamic> jsonMap = convert.jsonDecode(model);
//  print('jsonMap: $jsonMap');
//  UserInfoModel _model = UserInfoModel.fromJson(jsonMap);

  UserInfoModel _model1 =
  UserInfoModel.fromJson(convert.jsonDecode(params['userInfoModel'][0]));
  UserInfoModel _model2 =
      UserInfoModel.fromJson(convert.jsonDecode(params['userInfoModel2'][0]));

  return WxSharePage(
    userInfoModel: _model1,
    userInfoModel2: _model2,
  );
});
