+
+## What's Fluwx
+`Fluwx` is flutter plugin for [WeChatSDK](https://developers.weixin.qq.com/doc/oplatform/Mobile_App/Resource_Center_Homepage.html) which allows developers to call  
+[WeChatSDK](https://developers.weixin.qq.com/doc/oplatform/Mobile_App/Resource_Center_Homepage.html) native APIs.

+
+## Capability
+
+- Share images, texts, music and so on to WeChat, including session, favorite and timeline.
+- Payment with WeChat.
+- Get auth code before you login in with WeChat.
+- Launch mini program in WeChat.
+- Subscribe Message.
+- Just open WeChat app.
+- Launch app From wechat link.
+
+## Preparation
+
+[Migrate to V4 now](./doc/MIGRATE_TO_V4_CN.md)
+
+`Fluwx` is good but not God. You'd better read [official documents](https://developers.weixin.qq.com/doc/oplatform/Mobile_App/Resource_Center_Homepage.html) before
+integrating `Fluwx`. Then you'll understand how to generate Android signature, what's universal link for iOS, how to add URL schema for iOS and so on.
+
+## Install
+
+Add the following dependencies in your `pubspec.yaml` file:
+
+`Fluwx` with pay:
+
+```yaml
+dependencies:
+  fluwx: ^${latestVersion}
+```
+![pub package](https://img.shields.io/pub/v/fluwx.svg)
+
+`Fluwx` without pay:
+
+> Developers who need to exclude payment for iOS can enable `no_pay` in [pubspec.yaml](./example/pubspec.yaml#L86).
+
+
+> NOTE: Never forget to replace ^${latestVersion} with actual version.
+
+## Configurations
+
+`Fluwx` enables multiple configurations in the section `fluwx` of `pubspec.yaml` from v4, you can reference [pubspec.yaml](./example/pubspec.yaml#L10)
+for more details.
+
+> For iOS, some configurations, such as url_scheme，universal_link, LSApplicationQueriesSchemes, can be configured by `fluwx`,
+> what you need to do is to fill configurations in `pubspec.yaml`
+
+- app_id. Recommend. It'll be used to generate scheme on iOS。This is not used to init WeChat SDK so you still need to call `fluwx.registerApi` manually.
+- debug_logging. Optional. Enable logs by setting it `true`.
+- flutter_activity. Optional. This is usually used by cold boot from WeChat on Android. `Fluwx` will try to launch launcher activity if not set.
+- universal_link. Recommend for iOS. It'll be used to generate universal link on your projects.
+- scene_delegate. Optional. Use `AppDelegate` or `SceneDelegate`. See [official documents](https://developers.weixin.qq.com/doc/oplatform/Mobile_App/Access_Guide/iOS.html) for more details.
+
+* For iOS
+ If you are failing `cannot load such file -- plist` on iOS, please do the following steps:
+```shell
+# step.1 install missing dependencies
+sudo gem install plist
+# step.2 enter iOS folder(example/ios/,ios/)
+cd example/ios/
+# step.3 execute
+pod install
+```
+## Register WxAPI
+
+Register your app via `fluwx` if necessary.
+
+```dart
+Fluwx fluwx = Fluwx();
+fluwx.registerApi(appId: "wxd930ea5d5a228f5f",universalLink: "https://your.univerallink.com/link/");
+```
+The param `universalLink` only works with iOS. You can read [this document](https://developers.weixin.qq.com/doc/oplatform/Mobile_App/Access_Guide/iOS.html) to learn
+how to create universalLink. You can also learn how to add URL schema, how to add `LSApplicationQueriesSchemes` in your iOS project. This is essential.
+
+For Android, you shall know to how generate signature for your app in [this page](https://developers.weixin.qq.com/doc/oplatform/Downloads/Android_Resource.html).
+And you have to understand the difference between debug signature and release signature. Once the signature is incorrect, then you'll get `errCode = -1`.
+
+It' better to register your API as early as possible.
+
+## Capability Document
+
+- [Basic knowledge](./doc/BASIC_KNOWLEDGE.md)
+- [Share](./doc/SHARE.md)
+- [Payment](./doc/PAYMENT.md)
+- [Auth](./doc/AUTH.md)
+- [Launch app from h5](./doc/LAUNCH_APP_FROM_H5.md)
+
+For more capabilities, you can read the public functions of `fluwx`.

+
+## 能力
+
+- 分享图片，文本，音乐，视频等。支持分享到会话，朋友圈以及收藏.
+- 微信支付.
+- 在微信登录时，获取Auth Code.
+- 拉起小程序.
+- 订阅消息.
+- 打开微信.
+- 从微信标签打开应用
+
+## 准备
+
+[迁移到V4指南](./doc/MIGRATE_TO_V4_CN.md)
+
+`Fluwx` 可以做很多工作但不是所有. 在集成之前，最好读一下[官方文档](https://developers.weixin.qq.com/doc/oplatform/Mobile_App/Resource_Center_Homepage.html).  
+ 然后你才知道怎么生成签名，怎么使用universal link以及怎么添加URL schema等.
+
+
+## 安装
+
+在`pubspec.yaml` 文件中添加`fluwx`依赖:
+
+`Fluwx`，带支付:
+
+```yaml
+dependencies:
+  fluwx: ^${latestVersion}
+```
+![pub package](https://img.shields.io/pub/v/fluwx.svg)
+
+不带支付的`Fluwx`:
+
+> 一些开发者并不需要在iOS端使用支付能力，此时您可以通过在[pubspec.yaml](./example/pubspec.yaml).
+![pub package](https://img.shields.io/pub/v/fluwx_no_pay.svg)中开启`no_pay`。
+
+> NOTE: 别忘记替换 ^${latestVersion} ！！！！
+
+## 配置

+`Fluwx` 从v4开始可以在`pubspec.yaml`的`fluwx`进行一些配置。具体可以参考[pubspec.yaml](./example/pubspec.yaml#L10)。
+
+> V4开始，iOS中的url_scheme，universal_link, LSApplicationQueriesSchemes可以不必开发者手动配动。只需在`pubspec.yaml`
+> 中填写即可。
+
+- app_id. 推荐. 它将用于生成iOS的url_scheme。这并不会替你初始化微信SDK，所以你还是自己调用`fluwx.registerApi`。
+- debug_logging. 可选. 把它设置成`true`可以开启日志。
+- flutter_activity. 可选. 这个通常是用于Android的冷启动。如果不设置任何值，`Fluwx`将尝试启动launcher activity.
+- universal_link. iOS 推荐. 它将用自动配置universal_link。
+- scene_delegate. iOS 可选. 使用 `AppDelegate` 还是使用 `SceneDelegate`. 查阅[官方文档](https://developers.weixin.qq.com/doc/oplatform/Mobile_App/Access_Guide/iOS.html)了解更多.
+
+* For iOS
+如果你在iOS上遇到了 `cannot load such file -- plist`, 请按照以下步骤进行操作：
+```shell
+# step.1 安装必要依赖
+sudo gem install plist
+# step.2 进行iOS文件夹(example/ios/,ios/)
+cd example/ios/
+# step.3 执行脚本
+pod install
+```
+
+## 注册 WxAPI
+
+通过 `fluwx` 注册WxApi.
+
+```dart
+Fluwx fluwx = Fluwx();
+fluwx.registerApi(appId: "wxd930ea5d5a228f5f",universalLink: "https://your.univerallink.com/link/");
+```
+
+参数 `universalLink` 只在iOS上有用. 查看[文档](https://developers.weixin.qq.com/doc/oplatform/Mobile_App/Access_Guide/iOS.html) 以便了解如何生成通用链接.  
+ 你也可以学习到怎么在iOS工程中添加URL schema，怎么添加`LSApplicationQueriesSchemes`。这很重要。
+
+对于Android, 可以查看[本文](https://developers.weixin.qq.com/doc/oplatform/Downloads/Android_Resource.html)以便了解怎么获取app签名.
+然后你需要知道release和debug时，app签名有什么区别。如果签名不对，你会得一个错误 `errCode = -1`.
+
+建议越早注册越好。

doc/AUTH.md

+## AUTH
+
+The purpose of `sendWeChatAuth` is to get auth code and then get information for WeChat login.
+Getting `access_token` is not supported in `fluwx`. For `access_token`, please visit [official documents](https://developers.weixin.qq.com/doc/oplatform/Mobile_App/WeChat_Login/Development_Guide.html).
+
+```dart
+Fluwx fluwx = Fluwx();
+fluwx.authBy(which: NormalAuth(scope: 'snsapi_userinfo', state: 'wechat_sdk_demo_test'));
+ ```
+
+> WHY? I think we shall fetch access_token or user info at backend.
+

doc/AUTH_CN.md

+## 登录
+
+`sendWeChatAuth`的目的是为了获取code，拿到了code才能进行微信登录，可以通过[官方文档](https://developers.weixin.qq.com/doc/oplatform/Mobile_App/WeChat_Login/Development_Guide.html)查看具体流程。
+
+```dart
+Fluwx fluwx = Fluwx();
+fluwx.authBy(which: NormalAuth(scope: 'snsapi_userinfo', state: 'wechat_sdk_demo_test'));
+```
+
+> 为什么不支持获取用户信息？ 我认为获取用户信息应该后端来做，即使没有后端，你也可以在dart层自己实现.
+

doc/BASIC_KNOWLEDGE.md

+## Basic knowledge
+
+### Response from WeChat
+Actually, almost every result from functions like `share` or `pay` which call `sendRequest` in native doesn't makes sense. The `bool` value is the result of `sendRequest`.
+So if you want get the real result you shall do like this:
+
+```dart
+    var listener = (response) {
+      if (response is WeChatAuthResponse) {
+
+      }
+    };
+    fluwx.addSubscriber(listener); // subscribe response from WeChat
+    fluwx.removeSubscriber(listener);// unsubscribe response from WeChat
+```
+
+Or 
+```dart
+    var cancelable = fluwx.addSubscriber(listener);
+    cancelable.cancel(); // unsubscribe response from WeChat
+```
+Take a look at subclasses of `WeChatResponse` for help.
+
+> NOTE: If you get `errCode = -1`, please read the WeChatSDK document for help. There are to many cases lead to that.
+
+
+
+### Images in WeChat
+
+The are four built-in types  of  `WeChatImage` in `fluwx`:
+
+```dart
+  WeChatImage.network(String source, {String suffix});
+  WeChatImage.file(File source, {String suffix = ".jpeg"});
+  WeChatImage.asset(String source, {String suffix});
+  WeChatImage.binary(Uint8List source, {String suffix = ".jpeg"});
+```
+
+The priority of `suffix` is highest, `fluwx` will try to read suffix from paths if `suffix` is blank.
+
+The max size of image youcan share to WeChat is `10M`.`Fluwx` wil compress `WeChatImage` itself if it's  used as `thumbnail` or `hdImagePath`,  
+otherwise, it doesn't. However, you'd better compress thumbnail yourself as the result of compression is unpredictable.

doc/BASIC_KNOWLEDGE_CN.md

+## 基础知识
+
+### 微信回调
+
+实际上，像`shareToWeChat` or `payWithWeChat`这种的函数，底层上是调用了原生SDK的`sendRequest`方法，所以他们的返回结果意义不大，他们的返回结果仅仅是`sendRequest`的返回值。
+为了获取真实的回调，你应该这样做：
+
+```dart
+    var listener = (response) {
+      if (response is WeChatAuthResponse) {
+
+      }
+    };
+    fluwx.addSubscriber(listener); // 订阅消息
+    fluwx.removeSubscriber(listener);// 取消订阅消息
+```
+
+Or
+```dart
+    var cancelable = fluwx.addSubscriber(listener);
+    cancelable.cancel(); // 取消订阅消息
+```
+> 笔记: 如果你的 `errCode = -1`, 那请阅读微信官方文档，因为-1的原因数不胜数.
+
+### 图片
+
+有四种内置 `WeChatImage`:
+
+```dart
+  WeChatImage.network(String source, {String suffix});
+  WeChatImage.file(File source, {String suffix = ".jpeg"});
+  WeChatImage.asset(String source, {String suffix});
+  WeChatImage.binary(Uint8List source, {String suffix = ".jpeg"});
+```
+
+其中， `suffix` 优先级最高, 如果`suffix`是空白的，`fluwx` 将会尝试从文件路径中读取后缀.
+
+在分享图片的功能，图片不能超过`10M`.如果图片被用作`thumbnail` 或 `hdImagePath`，`Fluwx` 会对 `WeChatImage` 进行压缩,  
+否则不会压缩. 但是，最好还是自己压缩，因为不保证`fluwx`压缩效果。

doc/MIGRATE_TO_V4.md

+## Upgrade to V4
+
+`Fluwx v4` not only brings a lot exciting functionalities but also breaking changes。
+
+- Now we need to initialize the instance using `Fluwx fluwx = Fluwx()`
+- Listening response from WeChat changed to `subscribeResponse` and also adding `unsubscribeResponse` to support 
+  cancel listening.  
+- Keyword `wechat` in some functions is removed.
+- Some functions are extracted to a single function，and now you can pass different params instead.
+- Some configurations are moved to[pubspec.yaml](../example/pubspec.yaml)，for example, you can enable/disable log in `pubspec.yaml`.
+- `no_pay` can be enabled by [pubspec.yaml](../example/pubspec.yaml), reference example for more details.

doc/MIGRATE_TO_V4_CN.md

+## 升级到V4
+
+`Fluwx v4`带来了很多令人兴奋的功能，但也带来了少破坏性更新。
+
+- 现在我们需要使用`Fluwx fluwx = Fluwx()`初始化实例
+- 监听微信回调变成了`subscribeResponse`并且增加了`unsubscribeResponse`以支持取消监听
+- 很多带有`wechat`关键字的函数已经把`wechat`关键字删除了
+- 很多方法被整到了一个函数中，现在你可以传递不同的对象实现对应的业务
+- 一些配置被移动到了[pubspec.yaml](../example/pubspec.yaml)，可以通过`pubspec.yaml`配置是否开启日志等等

+
+## 常见Q&A
+
+#### Fluwx调起失败？
+请检查APPID、包名、以及App签名是否一致。debug 和release的签名默认不一样，请注意。
+
+#### Android Flutter编译失败
+1、检查Kotlin版本，打开```build.gradle```文件，查看以下配置
+```
+buildscript {
+	······
+	ext.kotlin_version = '1.3.11'
+	······
+}
+```
+确保项目中使用的Kotlin版本符合要求；
+2、检查Android目录下```build.gradle```文件中gradle插件版本：```classpath 'com.android.tools.build:gradle:3.2.1'```和```gradle-wrapper.properties```文件中的gradle版本是否匹配：```distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.1-all.zip```，两者的匹配规则见Android官网：[Update Gradle](https://developer.android.com/studio/releases/gradle-plugin.html#updating-gradle)
+
+#### WeChat Not Installed on iOS?
+iOS 9系统策略更新，限制了http协议的访问，此外应用需要在“Info.plist”中将要使用的URL Schemes列为白名单，才可正常检查其他应用是否安装。
+受此影响，当你的应用在iOS 9中需要使用微信SDK的相关能力（分享、收藏、支付、登录等）时，需要在“Info.plist”里增加如下代码：
+```xml
+<key>LSApplicationQueriesSchemes</key>
+<array>
+<string>weixin</string>
+</array>
+<key>NSAppTransportSecurity</key>
+<dict>
+<key>NSAllowsArbitraryLoads</key>
+<true/>
+</dict>
+```
+
+#### 如果没有安装微信，微信登录不了，导致iOS审核失败
+fluwx提供了检查用户是否安装微信的方法：```isWeChatInstalled()```，iOS使用微信相关功能前，务必先检查微信是否安装。
+
+#### Failed to notify project evalution listener
+[Failed to notify project evalution listener](https://www.jianshu.com/p/f74fed94be96)
+
+#### isWeChatInstalled返回false
+请查看该 [issue](https://github.com/OpenFlutter/fluwx/issues/34)  ，检查```AppDelegate```中配置是否正确。
+
+#### Kotlin报错：XXX is only available since Kotlin 1.3 and cannot be used in Kotlin 1.2
+1、请检查IDE安装的Kotlin插件版本是否符合fluwx要求：AS打开设置-->Plugin-->Koltin查看插件版本；
+2、请检查项目中使用的Kotlin版本：打开```build.gradle```文件，查看以下配置
+```
+buildscript {
+	······
+	ext.kotlin_version = '1.3.11'
+	······
+}
+```
+
+#### listen监听多次调用
+请查看该 [issue](https://github.com/OpenFlutter/fluwx/issues/36)  。这个问题是由于listen被多次注册导致的，使用者自己代码的问题，非fluwx导致的，请在合适的时机将listen cancel掉：
+```
+StreamSubscription<WeChatAuthResponse> _wxlogin;
+_wxlogin = fluwx.responseFromAuth.listen((val) {})
+@override
+  void dispose() {
+	_wxlogin.cancel();
+}
+```
+
+#### 分享完成或者取消分享后App崩溃
+如果你手动注册了```WXEntryActivity```and```WXPayEntryActivity```，请检查```Manifest```中包名是否写对了。
+
+#### IOS编译错误：No such module 'fluwx'
+如果项目本身是在Android环境配置的，移到iOS的环境的时候，会出现该问题，请按照正常步骤配置。
+
+#### 支付成功后，按物理按键或手机自动返回商户APP，监听不到返回数据
+
+有人反应会出现```fluwx.responseFromPayment.listen```监听无效，无法获取支付结果，建议可以直接向服务器查询是否成功。
+
+#### iOS报错：Specs satisfying the `fluwx (from `.symlinks/plugins/fluwx/ios`)` dependency were found, but they required a higher minimum deployment target.
+请在在pod file里将iOS项目deployment target改到9.0。
+
+#### ResponseType与Dio插件中的命名冲突
+使用as的方式导包即可：```import 'package:fluwx/fluwx.dart' as fluwx;```
+

doc/SHARE.md

+## Share
+Simple and easy:
+
+```dart
+ fluwx.share(WeChatShareTextModel("source text", scene: WeChatScene.SESSION));
+```
+The destination of sharing can be SESSION(default),TIMELINE or FAVORITE.However,mini-program only support SESSION.
+
+```dart
+    ///[WeChatScene.session]会话
+    ///[WeChatScene.timeline]朋友圈
+    ///[WeChatScene.favorite]收藏
+    enum WeChatScene {
+      session,
+      timeline,
+      favorite
+      }
+```
+
+You can share these models:
+
+- WeChatShareTextModel
+- WeChatShareMiniProgramModel
+- WeChatShareImageModel
+- WeChatShareMusicModel
+- WeChatShareVideoModel
+- WeChatShareWebPageModel
+- WeChatShareFileModel
+

doc/SHARE_CN.md

+## 分享
+简单:
+
+```dart
+ fluwx.share(WeChatShareTextModel("source text", scene: WeChatScene.SESSION));
+```
+绝大部分分享可以分享到会话，朋友圈，收藏（小程序目前只能分享到会话）。默认分享到会话。
+
+```dart
+    ///[WeChatScene.session]会话
+    ///[WeChatScene.timeline]朋友圈
+    ///[WeChatScene.favorite]收藏
+    enum WeChatScene {
+      session,
+      timeline,
+      favorite
+      }
+```

+# example
+
+A new Flutter project.
+
+## Getting Started
+
+This project is a starting point for a Flutter application.
+
+A few resources to get you started if this is your first Flutter project:
+
+- [Lab: Write your first Flutter app](https://docs.flutter.dev/get-started/codelab)
+- [Cookbook: Useful Flutter samples](https://docs.flutter.dev/cookbook)
+
+For help getting started with Flutter development, view the
+[online documentation](https://docs.flutter.dev/), which offers tutorials,
+samples, guidance on mobile development, and a full API reference.

example/analysis_options.yaml

+# This file configures the analyzer, which statically analyzes Dart code to
+# check for errors, warnings, and lints.
+#
+# The issues identified by the analyzer are surfaced in the UI of Dart-enabled
+# IDEs (https://dart.dev/tools#ides-and-editors). The analyzer can also be
+# invoked from the command line by running `flutter analyze`.
+
+# The following line activates a set of recommended lints for Flutter apps,
+# packages, and plugins designed to encourage good coding practices.
+include: package:flutter_lints/flutter.yaml
+
+linter:
+  # The lint rules applied to this project can be customized in the
+  # section below to disable rules from the `package:flutter_lints/flutter.yaml`
+  # included above or to enable additional rules. A list of all available lints
+  # and their documentation is published at https://dart.dev/lints.
+  #
+  # Instead of disabling a lint rule for the entire project in the
+  # section below, it can also be suppressed for a single line of code
+  # or a specific dart file by using the `// ignore: name_of_lint` and
+  # `// ignore_for_file: name_of_lint` syntax on the line or in the file
+  # producing the lint.
+  rules:
+    # avoid_print: false  # Uncomment to disable the `avoid_print` rule
+    # prefer_single_quotes: true  # Uncomment to enable the `prefer_single_quotes` rule
+
+# Additional information about this file can be found at
+# https://dart.dev/guides/language/analysis-options
