dim

封装的一个腾讯云im，以便于flutter开发者可以方便继承im到自己的应用中

使用之前注意事项

开发者需要到腾讯云上申请一个appid，申请地址

申请成功之后，平台会分配一个appid给到开发者。

1、sig的获取，sig一般就是开发者自己的后台开发同学提供，可以参考腾讯云文档实现sig申请。

2、都准备ok了，就可以登录imsdk了。

android 端配置你的项目中，android 目录app下面的 AndroidManifest.xml，内容参考这里

ios端配置:

因为git上传文件必须要小于100m的限制，所以云im有些framework上传不了，因此需要开发者自己到这里下载。

下载好了zip包之后，把里面的这些framework copy到 /Users/xxx/.pub-cache/hosted/pub.dartlang.org/dim-0.x.x/ios 目录下（注意，运行fetch_libs.sh获取所有的framework）.

随后到你的工程的ios文件夹中执行 pod install

然后就可以跑起来了。

如果不可以跑起来，报了这样的错误。

 Undefined symbols for architecture x86_64:
             "operator new[](unsigned long, std::nothrow_t const&)", referenced from:
                 openbdh::BdhUpTransaction::initSegmentList() in ImSDK(bdhUpTransaction.o)
                 openbdh::BdhUpTransaction::getData(openbdh::DataTransInfo*) in ImSDK(bdhUpTransaction.o)
             "std::__1::__throw_system_error(int, char const*)", referenced from:
                 std::__1::unique_lock<std::__1::mutex>::unlock() in ImSDK(task_queue.o)
             "_uncompress", referenced from:

这说明你本地的一些库没有引用，用xcode打开你的ios工程，然后参考这里这里如何集成IMSDK写的很清楚，需要依赖系统的那些库。

注意：

1、引入的时候搜索你会发现.dylib现在变为了.tbd了。还有就是IOS模拟器跑不了，腾讯云没有提供X86的framework。 2、注意不要引入IMUGCExt.framework,TXRTMPSDK.framework。 3、注意，当你升级dim之后，cache对应的版本中没有这些库了，因此要在copy一份过去,可以直接从你之前的版本中copy，在到ios工程下执行pod install。

已有的功能

1、登录

2、登出

3、获取会话列表

4、删除一个会话

5、获取会话消息
