中文文档 英文文档 问题集 原仓库不再维护，代码已经很老了

最近版本更新会很快，主要是增加新特性，涉及到混合栈的稳定性的问题应该不多，可放心升级，发现问题加 QQ 群号码：1014085473，我会尽快解决。

不打算好好看看源码的使用者可以放弃这个库了，因为很多设定是比较死的，而我本人不打算花时间写太多文档

优势

1. 稳定性、通用性在部分项目中得到验证，有用户反馈，将整个 app 的路由方案全部切换到后，崩溃率降低显著
2. 内存占用方面，thrio 在连续打开 Flutter 页面的内存占用方面从一开始就碾压主流的 Flutter 混合栈，更进一步的，避开原理层面带来的内存优势，这里有个对比，也说明 thrio 在内存占用上的优异表现，传送门
3. 支持 FlutterEngine 的复用，还支持 FlutterViewController 和 FlutterActivity 的复用，这保证了 Flutter 混合栈框架在内存占用上是最优解
4. 在 3 情形下，支持 跨栈路由 的能力，这是目前唯一能做到的 Flutter混合栈开源框架
5. 在 3 情形下，除了提供 push 和 pop，也提供了 remove 和 popTo 的能力，目前唯一能做到的 Flutter混合栈开源框架
6. 在 3 情形下，提供页面通知的能力，组合 push 和 pop 的路由传参能力，可以让状态参数在页面间传递，省去很多 channel 通讯的必要
7. 在 3 情形下，页面传参支持Json对象类型，单引擎下纯 Flutter 开发支持直接传递对象类型
8. 在 3 情形下，支持完整的页面生命周期
9. 在 3 情形下，支持完整的路由周期，兼容使用 Flutter 的 Navigator 来打开对话框等弹窗
10. 在 3 情形下，支持多引擎模式，可以在一个原生 App 中运行多份 Flutter 代码，目前唯一能做到的 Flutter 混合栈开源框架
11. 在 3 情形下，解决 iOS 和 Android 上的侧滑返回手势冲突
12. iOS 上自动隐藏 Flutter 页面的导航栏
13. 额外的支持三端统一的模块化方式，更好的与路由API配合

劣势

1. 在 iOS 上不支持 present，技术上完全可以实现，甚至使用者可以通过传参的方式在 builder 中自己 present，但为了 API 设计上统一，作者选择不支持 present，demo 中其实是有 present 的示例的，建议 present 的时候外套一个 UINavigationController，可以保证不管何时 push 时 API 都是有效的，flutter_thrio 是支持多 UINavigationController 的，有一点需要注意的是，如果多个 UINavigationController 内嵌于 UITabBar 中时，要注意无法同时将多个 FlutterViewController 呈现，不支持是因为支持的话无法进行引擎复用。
2. 在 Android 上不支持 Fragment，原因是复杂性无法解决，作者目前不能够保证提供一个通用稳定的版本。

入门

1. clone thrio 的源码，查看 demo，并运行起来
2. 通过 pub 引入 thrio，建议采用 1.0.0 之后的版本，之前的版本支持1.22.x之前的Flutter SDK，但不建议继续采用这些老版本的 SDK，还是尽快升级到新版
3. 模仿 thrio demo 中的源码，在现有工程上加入相关代码
4. 不要继承 Flutter SDK 中的一些类，比如 FlutterViewController、FlutterActivity、FlutterAppDelegate 等
5. 不要调用 GeneratedPluginRegistrant 的 registerWithRegistry 方法了，因为框架会自动调用
6. url 至少保持两段

最后

1. 技术没有好与不好，使用在适合的场景才是最好的。

2. Flutter 在 客户端的适用场景会越来越广，个人比较看好。

3. 目前在移动端，一个好的 Flutter 混合栈框架是必须的，让你可以在大多数的页面上采用 Flutter 来开发从而达到提效的目的，少数涉及到 Flutter 不能很好支持的页面上继续使用原生开发，从而规避的 Flutter 的坑。

4. 如果所开发的是一个全新的 App，以后也不会涉及到老的代码的复用，或者不会涉及到 Flutter 支持不够良好的一些技术上的坑，确实可以考虑纯 Flutter。

5. 但4的情形极少，所以大部分的 Flutter 在引入的时候，都应该考虑以 Flutter 混合栈的方式进行，坑不是用来踩的，而是绕道而过。

flutter_thrio's Issues

iOS多引擎模式下popTo的问题

多引擎下，popTo如果跨多个引擎，会导致某些引擎的页面并没有同步

Android 端 返回键的问题(iOS的效果不知道)

官方的flutteractivity里, 按返回键(手机的物理按键) 它会先弹出flutter 的堆栈里的页面(触发 dart: Navigator.of(context).pop();) ,当无页面可弹时 他才会关闭当前activity (触发 dart: SystemNavigator.pop();)
例如: 入栈:A(原生) -> B1(flutter) -> B2(flutter) -> B3(flutter) (B1 到 B2 B3 是通过 Navigator.of(context).push()来跳转的 而非其他方式)
按返回键 B3(flutter) -> B2(flutter) -> B1(flutter) -> A(原生)

而 thrio ,按返回键时(手机的物理按键) ,他不会弹出flutter 的堆栈里的页面 而是直接关闭当前activity .
例如: 入栈:A(原生) -> B1(flutter) -> B2(flutter) -> B3(flutter) (B1 到 B2 B3 是通过 Navigator.of(context).push()来跳转的, 而非 Thrio 的方式)
按返回键 B3(flutter) -> A(原生) (直接关闭了整个flutter)

请问这种情况该咋处理? 我需要通过 Thrio 的页面打开方式 ,而不能用flutter的 Navigator.of(context)方式?

0.4.3 Android代码 RouteSettings中的fromArguments方法返回了可空类型的RouteSettings? 导致编译异常

版本

0.4.3

问题描述

RouteSettings 中的 fromArguments方法的返回值返回了可空类型的RouteSettings?，导致NavigationController 中doPush方法中的 settings.isNested = PageRoutes.hasRoute(pageId)和val route = PageRoute(settings, activity::class.java)编译异常

RouteSettings

fun fromArguments(arguments: Map<String, Any>): RouteSettings? {
            if (arguments == null || !arguments.containsKey("url")) {
                return null
            }
            val url = arguments["url"] as String
            val index = if (arguments["index"] != null) arguments["index"] as Int else 0
            val params = arguments["params"]
            val animated = if (arguments["animated"] != null) arguments["animated"] as Boolean else false
            return RouteSettings(url, index).also {
                it.params = params
                it.animated = animated
            }
        }

NavigationController

 fun doPush(activity: Activity) {
            if (routeAction != RouteAction.PUSH) {
                result = null
                poppedResult = null
                return
            }
            routeAction = RouteAction.PUSHING

            checkNotNull(result) { "result must not be null" }
            val settingsData = activity.intent.getSerializableExtra(NAVIGATION_ROUTE_SETTINGS_KEY).let {
                checkNotNull(it) { "push params not found" }
                it as Map<String, Any>
            }

            val settings = RouteSettings.fromArguments(settingsData) // 返回值为可空类型
         
           // 直接使用可空类型导致编译失败
            settings.isNested = PageRoutes.hasRoute(pageId) 
            val route = PageRoute(settings, activity::class.java)
        
    }

支持 url 的正则校验

请问这个插件是配合flutter_module一起使用的吗？还有如何把flutter作为第一启动，而不是直接跳到OC页面？

为什么在flutter_module里加的thrio插件会比github上的例子少一些类呢？

能否在IntentBuilder中的build方法里加上params: Any? 的参数？？？

现状：

目前是混合开发，Flutter会跳转至现有native页面，但是现有native页面已有相关参数跳转方式，如果要再通过NAVIGATION_ROUTE_SETTINGS 获取参数成本太高，相当于一个activity有两套参数获取方式。

建议：

如果在IntentBuilder 的build方法中加入params字段即可解决问题，代码如下：

object FlutterModule : ThrioModule(), ModuleIntentBuilder {
    override fun onIntentBuilderRegister(context: Context) {
        registerIntentBuilder("native1", object : IntentBuilder {
            override fun getActivityClz(): Class<out Activity> {
                return SecondActivity::class.java
            }

            override fun build(context: Context, entrypoint: String, params: Any?): Intent {
                params as HashMap<String, Any>
                return Intent(context, SecondActivity::class.java).apply {
                    putExtras(Bundle().apply {
                        putString("nativeKey", params["key"].toString())
                    })
                }
            }
        })
    }
}

Android ThrioFlutterView.resetWillNotDraw 异常报错

具体堆栈如下：

源码如下：

private fun resetWillNotDraw(isAccessibilityEnabled: Boolean, isTouchExplorationEnabled: Boolean) {
        if (!attachedFlutterEngine!!.renderer.isSoftwareRenderingEnabled) {
            setWillNotDraw(!(isAccessibilityEnabled || isTouchExplorationEnabled))
        } else {
            setWillNotDraw(false)
        }
    }

是否因为使用!符是的应用异常报错

popTo可否支持数据传递params

1. FlutterViewController中从栈底至栈顶依次为页面A -> 页面B -> 页面C。
2. 现在使用popTo 至页面A。
3. 如何从页面C，通过popTo携带参数至页面A

增加Module Id，页面注册只需要注册页面名称，页面的URL = /[ModuleId]/[SubModule]/[PageName]

这个错误是什么导致的？

使用 image_picker，报错 (PlatformException(multiple_request, Cancelled by a second request, null))

用户多次触发channel调用，导致self.result 设置成nil。然后用户cancel时调用imagePickerControllerDidCancel时 调用self.result未做保护导致crash

- (void)handleMethodCall:(FlutterMethodCall *)call result:(FlutterResult)result {
  if (self.result) {
    self.result([FlutterError errorWithCode:@"multiple_request"
                                    message:@"Cancelled by a second request"
                                    details:nil]);
    self.result = nil;
  }
  //略...
}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
  [_imagePickerController dismissViewControllerAnimated:YES completion:nil];
  self.result(nil);

  self.result = nil;
  _arguments = nil;
}

我是新手，请问这个怎么处理

安卓期望开放FlutterEngineFactory

因为需要加入自定义的引擎，希望可以用这个object以获得当前的cache_engine，做到复用

[Android] 在native pop到flutter的时候，activity可能丢失

• Thrio v.0.2.1
• Flutter v1.17.2 stable channel
• Android

问题描述：

在flutter和native进行push和pop的过程中，flutter所在的activity可能丢失

复现方式：

flutter_thrio的example demo，做如下修改：

1. lib/src/sample/module1/page1.dart

加入一个输入框, 放在页面中

import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';
import 'package:thrio/thrio.dart';

class Page1 extends StatefulWidget {
  const Page1({
    Key key,
    this.index,
    this.params,
  }) : super(key: key);

  final int index;

  final dynamic params;

  @override
  _Page1State createState() => _Page1State();
}

class _Page1State extends State<Page1> {
  TextEditingController _inputController;
  @override
  void initState() {
    _inputController = TextEditingController();
    super.initState();

    if (mounted) {}
  }

  @override
  void dispose() {
    _inputController.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) => NavigatorPageNotify(
      name: 'page1Notify',
      initialParams:
          widget.params == null ? null : widget.params['page1Notify'],
      onPageNotify: (params) =>
          ThrioLogger.v('flutter1 receive notify:$params'),
      child: Scaffold(
          appBar: AppBar(

                  ]),
            ),
          )));
}

2. 运行demo，按照如下顺序push
   native1->flutter1->native1->flutter1
   可见每次flutter1都是会打开键盘，准备输入的

3.然后按照顺序pop回来
flutter1->native1-> flutter1
当页面回到flutter1的时候，键盘不打开了，无论加入SystemChannels.textInput.invokeMethod('TextInput.show'); 都是不可行

4. 猜测在此时embedded flutterActivity已经被干掉,并且每次做pop操作的时候都会报错

报错信息：
E/FlutterEnginePluginRegistry( 7345): Attempted to notify ActivityAware plugins of onNewIntent, but no Activity was attached.
E/FlutterEnginePluginRegistry( 7345): Attempted to detach plugins from an Activity when no Activity was attached.

此问题影响在此flutterActivity上的一系列插件，都变得不可用

请问下flutter作为第一屏 flutter—>native1 报这个错是什么原因

第二次从native页面打开flutter页面黑屏

第一次native打开flutter正常，再执行pop返回native页面，再次从native打开同一个flutter页面，黑屏

flutter_boost 迁移到 flutter_thrio 的成本大么？

[iOS] 如何自定义 NavigatorFlutterViewController ?

我通过继承 NavigatorFlutterViewController

NavigatorFlutterPageBuilder pageBuilder = ^NavigatorFlutterViewController* {
     return [[CustomFlutterViewController alloc] initWithEntrypoint:@""];
};
[self setFlutterPageBuilder: pageBuilder];

进入 Flutter 页面是白屏，请问正确的自定义方式是什么？

在Android端提供多引擎模式

Android端提供多引擎消耗会较小，这个特性目前优先级不是很高

RedMi Note3首次进入跳转能看到很明显的黑屏，望解决

适配 1.17.x

主要问题是 Navigator 2.0 中 RouteSettings 去掉了 isInitialRoute 这个属性，thrio 目前复用了这个属性

高版本Xcode创建的iOS工程，以flutter_module方式引入插件，获取 navigationController 可能为空

高版本Xcode创建的工程，因为SceneDelegate缘故
UIApplication+Thrio.m , topmostNavigationController 方法中，
UIViewController *topmostViewController = self.delegate.window.rootViewController;获取可能为nil

改造 notify，如果不传入 index，默认通知所有对应的 url 页面

适配1.20.x

#62

内存泄露严重

我在Appdelegate中 执行[ThrioModule init:[RootThrioModule new]]; 代码之后，App一启动，内存就在不断增加。flutter版本是stable 1.75.5,希望给出解答

在Android提供统一的页面生命周期观察者

Android端要能观察包括Dart页面和通过thrio打开的页面的生命周期

Android打开Flutter页面，首屏加载出现白屏闪闪

Debug下比较明显，Release相对好些，带优化

能使用在flutter1.7.8+hotfix.4版本中吗？

能使用在flutter1.7.8+hotfix.4版本中吗？

请问我应该怎么注册自己的 Method Channel 呢

请问 iOS 应该怎么注册自己的 Method Channel 呢

ThrioChannel 暴露了方法：
- (void)setupMethodChannel:(NSObject<FlutterBinaryMessenger> *)messenger

messenger参数应该怎么传呢

remove操作可能导致返回按钮不一致

场景：thrio允许remove最底部的页面A，这样会使该页面的上一个页面B变成最底部的页面
问题：如果B页面为原生，iOS中导航栏上返回按钮会自动消失，如果B页面为Flutter页面，返回按钮会继续出现。
此问题优先级并不高。

改造push，接收锁打开的页面关闭的回调

目前遇到这种需求，需要改造API

Flutter内通过ThrioNavigator push时参数不支持自定义对象

比如：

List<Friend> friends = .....
ThrioNavigator.push(url:"example1", params: friends.first)

会报 Friend 未定义异常，我查看了一下Thrio 的逻辑，大概是因为 Thrio 总是会去调用原生的部分，文档里有提到优先打开原生页面，原生打不开才会尝试打开Flutter页面，而这个flutter的自定义类在原生下肯定是 undefined 的

不知道这种情况是已知问题还是未曾发现.

_{Sent from PPHub}

真机运行正常，模拟器运行报错

希望加入AndroidX的适配

宿主工程AndroidX，gradle过不去

dart页面，如果只剩下一个在容器页面上的时候，remove操作没有把原生页面pop掉

hot restart导致pop失效

Android端 minSdkVersion 为 21 (Android 5.0),是不是有点高了

希望能调低一点 minSdkVersion ,尽量兼容旧系统吧
😁😁😁😁😁😁

ios UIImagePickerControllerDelegate 被thrio替换掉了，导致未响应

建议 Android 中自定义FlutterView等的代码切换成java的是否会更好

现在自定义的flutteractivity 是使用的kotlin编写的, 但他的源码FlutterActivity等是java编写的. 并且flutter又是频繁更新, 如果把自定义的flutter的编译语言切换回java, 在官方更新了FlutterActivity等相关代码时, 通过对比等能更方便去更新自定义的Activity等代码.

flutter端 url 带点的问题 "."

我自己的url里面带"." 正好thrio里关于url的解析也带"." 这就导致了url错误的问题.
建议调整一下获取原始url方法

在Android上实现PageObserver和RouteObserver

添加 Android 路由日志开关

请适配最新版本

在flutter 1.20.2 channel stable Dart 2.9.1版本下点击跳转到flutter无反应

大佬，这个是错误是怎么导致的，排查了快一天了。
