出现问题：
在Flutter module编译过程中控制台报错如下
Error output from CocoaPods:
↳
[!] `<PBXGroup path=`Config` UUID=`741F49642135620F001E2961`>` attempted to initialize an object with an unknown UUID. `7497404A213559E7008C567A` for attribute: `children`. This can be the result of a merge and the unknown UUID is being discarded.
解决方案：
1.打开Flutter工程下的iOS工程
将 Podfile中的platform :ios, '8.0'改为platform :ios, '9.0'
示例：
platform :ios, '9.0'
在iOS项目下终端执行pod install
返回Flutter重新执行flutter run 即可
2.如果iOS工程中有此引用，
路径General->Linked Frameworks and libraries
移除其libPods.a
在iOS项目下终端执行pod install
返回Flutter重新执行flutter run 即可
