Issues
1，demo对应的flutter版本是？
答：stable分支3.7.3
2，支持哪些平台？
答：因为sdk的原因demo目前只能运行在android跟ios设备上
3，android安装包debug可以运行但release启动白屏？
答：flutter的release包默认是开启了混淆，可以使用命令：flutter build release --no -shrink，如果此命令无效可如下操作
在android/app/build.gradle配置的release配置加入以下配置
release {
minifyEnabled false
useProguard false
shrinkResources false
}
4，代码必须混淆怎么办？
答：在混淆规则里加入以下规则
-keep class io.openim.**{*;}
-keep class open_im_sdk.**{*;}
-keep class open_im_sdk_callback.**{*;}
5，android安装包不能安装在模拟器上？
答：因为Demo去掉了某些cpu架构，如果你想运行在模拟器上请按以下方式：
在android/build.gradle配置加入
ndk {
abiFilters "arm64-v8a", "armeabi-v7a", "armeabi", "x86", "x86_64"
}
6，ios构建release包报错
答：请将cpu架构设置为arm64，然后依次如下操作
- flutter clean
- flutter pub get
- cd ios
- pod install
- 连接真机后运行Archive
7，ios运行的最低版本号？
答：13.0
