FlutterBoost

A next-generation Flutter-Native hybrid solution. FlutterBoost is a Flutter plugin which enables hybrid integration of Flutter for your existing native apps with minimum efforts. The philosophy of FlutterBoost is to use Flutter as easy as using a WebView. Managing Native pages and Flutter pages at the same time is non-trivial in an existing App. FlutterBoost takes care of page resolution for you. The only thing you need to care about is the name of the page(usually could be an URL). 

Prerequisites

1. Before proceeding, you need to integrate Flutter into your existing project.
2. The Flutter SDK version supported by Boost 3.0 is >= 1.22

Flutter SDK version support:

1. Flutter SDK 3.0 and above, use a version greater than 4.0.1
2. Flutter SDK 3.0 or below, use v3.0-release.2 or below
3. The null-safe version that supports Flutter SDK 2.5.x is 3.1.x

Getting Started

Add a dependency in you Flutter project.

Open you pubspec.yaml and add the following line to dependencies:

flutter_boost:
    git:
        url: 'https://github.com/alibaba/flutter_boost.git'
        ref: '4.5.4'

flutter_boost's Issues

demo在iOS中跳转 有闪动的情况 请问怎么解决

closePageForContext后有闪动的情况 效果很不理想

example跑不起来？

as打开example下的android目录，提示dart sdk 找不到，

打开example目录，
一直 D:\flutter\bin\flutter.bat --no-color packages get

怎么没输出结果？

正确的姿势是？

android：activity包含若干个BoostFlutterFragment，只显示一个

activity viewpager包含5个BoostFlutterFragment的子类，一直只会显示一个fragment，其它的均空白无内容

Flutter工程加入到已有的Native APP，该如何集成？

再问一个问题，如果我把Flutter工程加入到已有的NativeAPP中 ，采取官方的集成方式https://github.com/flutter/flutter/wiki/Add-Flutter-to-existing-apps 请问Native工程如何接入flutter_boost？？？

flutter_boost混合项目，aos打包安装后问题两则

1.部分手机安装报错找不到对应的 libflutter.so。但是又不能把所有so都加进去，包太大了，你们是怎么处理的？类似：
buildTypes {
abiFilters "armeabi-v7a",'arm64-v8a'
}
2.有人尝试过weex和flutter的混合工程吗？我目前的包是 native+weex+flutter，native页面加载正常，weex的framework初始化抛错了：

整理了下，上面2个其实是一个问题，
1.不加上 abiFilters 'arm64-v8a'，米6的arm64手机，抛出找不到 libflutter.so
2.加上了 abiFilters 'arm64-v8a'，weex的集成要求就是不支持 arm64-v8a的so。所以 abiFilters "armeabi-v7a"只有这一项。
那么矛盾来了，加/不加都有问题，请教下有人遇到过吗？这种问题怎么解决？

建议增加路由无法响应方法

正常情况，dart端在这里注册路由实现：FlutterBoost.singleton.registerPageBuilders({});
原生端 - (void)openPage:(NSString *)name params:(NSDictionary *)params animated:(BOOL)animated completion:(void (^)(BOOL))completion;
在这个方法调用路由。

如果这边push了一个未注册的page name。页面会直接红屏报错。
强烈建议在 FlutterBoostPlugin 类新增一个判断页面是否注册的方法

怎么实现原生主动给 flutter 发消息

怎么实现原生主动给 flutter 发消息

Application 偶现空指针异常

这样集成应该不对把，Application中init获取MainAppActivity.sRef.get(); 这时候MainAppActivity还没有启动，可能存在空指针的。
看下异常信息：

在 iOS 中应该在何处监听 openPage 事件，实现从flutter open native page

在 iOS 版的 example 中，“push native” 是通过 native 的方法实现的，若想从 flutter 中 push 到 native 页面，请问应该如何实现。

纯flutter项目中有需要有一个页面要跳原生然后由原生再跳flutter页面问题

在纯flutter项目中
1、纯flutter项目中boost在哪里初始化
2.纯flutter项目中要用boost是不是需要在原生的mainactivity来启动一个flutter的container来驱动

android 第一次加载flutter的界面很慢

android 第一次加载flutter的界面很慢 缓冲大概3-5秒 之后打开就快了 有没有什么方式在打开APP时就分配flutter资源 使得第一次打开flutter界面更快

flutter sdk 1.2.x 版本ios引入boost到现有项目，打开第一个页面时候，出现花屏的现象？打release包也是一样。

原生页面返回到 flutter 页面，状态栏颜色怎么刷新？

flutter 页面状态栏为黑色模式，原生页面A为白色模式。
当跳转到原生的时候，状态栏的颜色变化了，然后切回到 flutter页面，状态栏颜色变成为原生页面A的颜色。 有没有提供一个监听接口，页面重新返回到可视视图的时候，进行回调？

错误: 不兼容的类型: ApplicationLike无法转换为Application

项目中MyApplicationLike 继承了 DefaultApplicationLike 集成了(tinker)
编译时报错
错误: 不兼容的类型: MyApplicationLike无法转换为Application
错误: 不是封闭类: MyApplicationLike

@DefaultLifeCycle(application = "com.MyApplication",
flags = ShareConstants.TINKER_ENABLE_ALL,
loadVerifyFlag = false)
public class MyApplicationLike extends DefaultApplicationLike

FlutterMain.startInitialization(getContext());
FlutterBoostPlugin.init(new IPlatform() {
@OverRide
public Application getApplication() {
return MyApplicationLike.this;
}
...

请问这个问题应该怎么解决？谢谢

example代码Flutter跳Native的传参问题

建议修改一下example代码中PageRouter的代码，因为实际上传过来的url是一个Uri，包含参数，示例代码的问题：
1.带参情况下，如果用equals作判断，无法判断准确，用startWith会否好一点？
2.可以把解析参数作为Bundle传入activity的方式补充一下，以方便初学者学习？

开发一个全新的flutter app,请问可以用flutter_boost么？

请问开发一个全新的flutter app,请问可以用flutter_boost么？ 或者说有有没有更好的解决方案或者是直接使用flutter就可以？

Flutter页面启动 Activity页面，如何拿到参数?

Flutter页面代码：
FlutterBoost.singleton.openPage("pagename", {"key":"value"});
Android代码
FlutterBoostPlugin.init(new IPlatform() { ........... /** * start a new activity from flutter page, you may need a activity router. */ @Override public boolean startActivity(Context context, String url, int requestCode) { return PageRouter.openPageByUrl(context, url, requestCode); } .......... });

Flutter启动Android Activity，请问下Android代码 startActivity(Context context, String url, int requestCode)怎么拿到Flutter中传过来的参数key,value????

添加到现有项目，打开flutter页面只显示加载

native打开flutter页面，一直出现加载页面，并有如下报错：

iOS native 引入flutter_boost后，单独运行 flutter 工程到 iOS 设备报错。

原生项目增量覆盖 flutter_boost/example/android/app 后，遇到的问题两则：

1. BoostFlutterActivity的实现代码，即flutter_boost/android/src 下所有java文件，大家务必自己格式化一下。否则你可能会遇到如下问题：

这个比较坑，里面的种种**空格符**会让你的ide各种飙红（代码没问题，格式有问题）。 根本原因不太清楚，不过靠一个一个手动格式化文件，就可以解决！

2.排除万难终于sync success，build的时候遇到了:xservice_kit 里面一个build.grade的问题，具体是：

求解这个存在于 :xservice_kit Tasks/other/transformDexArchiveWithExternalLibsDexMerge
需要我在example/app的build.grade 添加什么task吗？

使用flutter_boost之后 无法使用Hero 动画

使用flutter_boost 之后无法使用Hero动画，如果需要这种动画，该如何实现。

flutter_boost 0.0.39版本无法使用

我在pubspec.yaml中配置了依赖flutter_boost: ^ 0.0.39，但是实际拉下来的版本是flutter_boost-0.0.344版本，而我从来没有配置过这个版本，导致我在main函数初始化报错，找不到registerPageBuilders方法。什么原因？？？

iOS 运行你们给的demo，push很多页面，内存从50M升到130M。pop到根控制器内存才降了10M，我的flutter版本是1.0.0

最开始是flutter页面如何初始化boost是把flutter页面放在MainActivity中？怎么来初始化这两个容器

传参问题

场景：我从flutter跳原生需要传参，原生一个acitivity点击后发现没登录需要跳转flutter登录页面，登录成功需要回传值到这个原生页面,怎么处理？

请教个问题：addBackPressedListener 怎么具体去覆盖默认物理返回键的回调的？

native--> flutter1-->flutter2
1 flutter1 通过 openPage 方式 打开flutter2， 物理键回退没有问题
2 flutter1 通过 Navigator.push(context, MaterialPageRoute(builder: (context) => FirstRouteWidget()))方式 打开flutter2， 物理键回退会直接到native ， 这种场景能不能控制一层一层回退的？

请问如何可以通过BoostContainer.of(context).addBackPressedListener(listener)去覆盖默认物理返回键的回调。

请问下这个方法 BoostContainer.of(context).addBackPressedListener(listener) 具体怎么使用嘛？
flutter 和 Android 原生，分别应该怎么使用的，能详细说明下吗，谢谢

提示FlutterBoost#ManagerNavigatorObserver didPush 但是页面没跳转

进行的跳转是dart内部跳转：

首先定义了路由：

    FlutterBoost.singleton.registerPageBuilders({
      'main': (pageName, params, _) => MyHomePage(),
      'news': (pageName, params, _) => NewsDemo(),
    });

然后跳转:

FlutterBoost.singleton.openPage("news", {});

结果就只打印了个结果，页面没跳，啥情况？

dart跳native activity是可以跳的

I guess this is related to libstd++. Which version of Xcode are you using? Can you show this section of from Build Settings?

How can i specify a --flavor option for Android when compiling flutter?

因为原生项目有个productFlavors：flavors_dev1，构建原生没问题，起来了。 但是构建整个flutter时，IDE需要我指定flavor,搜了下官网，没找到什么有用的信息/指令，你们有遇到过类似的情景吗？

AndroidView去加载webview无法显示

场景：
flutter端 从 A页面跳转到B页面 并且销毁A页面，在B页面通过androidview 加载一个原生的webview页面。但是无法显示出来。

初步定位：
1、flutterview 是单例，所以FlutterPluginRegistry的attach的时候，context是A页面的。
2、在PlatformViewFactory 的create 方法里面 context是SingleViewPresentation持有的，也就是A页面的context。但是A已经销毁了，所以显示不出来。

问题：有些手机是android 9.0的可以显示出来的，但是我手头上的一个pad是7.0的就无法显示。

这个有解吗？

FlutterBoost.singleton.addBoostNavigatorObserver not working

addBoostNavigatorObserver 之后没用收到任何回调
版本 0.0.401

Question: 和 hybrid_stack_manager 定位上的区别？

flutter_boost 和 hybrid_stack_manager 目测都是闲鱼推出的、用来管理混合栈的解决方案.

由于 hybrid_stack_manager 需要在 Flutter 源码里添加一行代码，尝试了一下就放弃了（看上去关注度和活跃度也都不高）.

这次又推出的 flutter_boost ，号称 “新一代Flutter-Native混合解决方案”。请问和 hybrid_stack_manager 实现的作用上，或者二者的定位上，有什么较大的区别么？

Should I move all existed native code to flutter project as example showed?

请教一个问题

看了本项目的ios demo, 初始界面的时候有一个 tab 是使用了 flutter页面， 想问如果不需要这种，只在2级以上的页面，某项操作后触发跳转到 flutter 页面，那么怎么进行初始化？

+ (instancetype)shared {
    static FlutterModule *module = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        module = [[FlutterModule alloc] init];
    });
    return module;
}

- (instancetype)init {
    if (self = [super init]) {
        self.router = [[FlutterRouter alloc] init];
    }
    return self;
}

- (void)setup {
    [FlutterBoostPlugin.sharedInstance startFlutterWithPlatform:self.router
                                                        onStart:^(FlutterViewController *fvc) {
    }];
}


- (void)jumpLifeDetailWithCatId:(NSInteger)cateId
                            tid:(NSString *)tid
                 pushController:(nonnull UIViewController *)pushController {
    NSString *type = [PostTool getLifeTableNameWithCatId:cateId];
    self.router.navigationController = pushController.navigationController;
    [self.router openPage:@"life_detail" params:@{@"cateId": @(cateId), @"tid": tid, @"type": type} animated:YES completion:^(BOOL finished) {

    }];
}

然后我这边是在 appdelegate 的入口调用 [[xxx shared] setup];

但是我打开的页面为空白

`xservice_kit` spelling incorrect.

I found some getHanlderBlockForType: spelling error in xservice_kit, but I cannot found any repo for it. So issued it here because I find the xservice_kit author same as this project.

引入boost后，单独打开flutter项目不行吗？

java.lang.IllegalStateException: Activity has been destroyed

1. 请教一个问题： 现象描述
   1首页打开首页，MainActivity,（比如地址为@1）,

2. 点击flutter页面，进行 GeneratedPluginRegistrant.registerWith(registry); 注册，此时
   alreadyRegisteredWith 方法返回false,进行注册
   public static void registerWith(PluginRegistry registry) {
   if (alreadyRegisteredWith(registry)) {
   return;
   }
   xx.registerWith(registry.registrarFor("xx")); //这个地方就注册了一次，里面调用了registrar.activity();
   }

   public static void registerWith(PluginRegistry.Registrar registrar) {
   final MethodChannel channel = new MethodChannel(registrar.messenger(), "xx");
   channel.setMethodCallHandler(sInstance);
   mActivity = registrar.activity(); // 这个地方一直是第一次MainActivity
   }

private static boolean alreadyRegisteredWith(PluginRegistry registry) {
final String key = GeneratedPluginRegistrant.class.getCanonicalName();
if (registry.hasPlugin(key)) {
return true;
}
registry.registrarFor(key);
return false;
}
3. 退出flutter，再次进入flutter alreadyRegisteredWith 返回TRUE， 没有问题
4. 退出首页，再次打开 MainActivity，（此时地址变为@2），这两次的MainActivity 是不一样的，第一次的已经销毁了，但是 进入flutter页面 alreadyRegisteredWith 还是返回TRUE，不会重新进行注册，为什么？
5. MainActivity 包含了fragment，
没有退出首页时，第一次 activity.getFragmentManager() 不为空，
再次进入后，不会重新注册， 注册的地方用到的 mActivity = registrar.activity()，还是第一次的activity，但是第一次的已经销毁了了 activity.getFragmentManager() 为空了

错误日志
java.lang.IllegalStateException: Activity has been destroyed
at android.app.FragmentManagerImpl.enqueueAction(FragmentManager.java:1350)
at android.app.BackStackRecord.commitInternal(BackStackRecord.java:729)
at android.app.BackStackRecord.commitAllowingStateLoss(BackStackRecord.java:709)

2, 怎么退出首页之后，再次打开，重新注册，{alreadyRegisteredWith 方法返回false,进行注册}？

3. native--> flutter1-->flutter2 , 顶部回退可以正常回退， flutter2-->flutter1-->native;
   按物理键返回，直接返回到native了，请问怎么实现控制，一层一层回退？
