Flutter中fluro使用

使用fluro时，对参数进行URLEncode来解决找不到路由的问题

一、使用方法

1、route_handlers.dart中新建对应页面的Handler
2、routes.dart中定义对应的路由

二、跳转页面

1. 跳转页面，不传参：

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

2. 跳转页面，传递字符串参数：

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

3. 跳转页面，传递model参数或字符串参数：

UserInfoModel userInfoModel =
          UserInfoModel('袁致营', 30, 1.78, 74.0);
      UserInfoModel userInfoModel2 =
      UserInfoModel('袁致营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) {
        // 通过pop回传的值，边缘策划返回则不努力通过此处传值

      });

三、返回页面

1、pop返回页面：

Navigator.of(context).pop();

2、返回到/根页面：

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个页面：

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

或返回fluro中设定的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
    );

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);
  }
}

创建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';

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

// 设置页 - 示例：不传参数
var settingHandler =
    Handler(handlerFunc: (BuildContext context, Map<String, dynamic> params) {
  return Settings();
});

// 网页加载 - 示例：传多个字符串参数
var webViewHandler =
    Handler(handlerFunc: (BuildContext context, Map<String, dynamic> params) {
  // params内容为  {title: [我是标题哈哈哈], url: [https://www.baidu.com/]}
  String title = params['title']?.first;
  String url = params['url']?.first;
  return WebViewUrlPage(
    title: title,
    url: url,
  );
});

// 示例：传多个model参数
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,
  );
});
