Flutter调用原生方法并且传参
Flutter
Future reportError(errorJson)async{
const platform = const MethodChannel("com.xxx.xxx");
var result;
try{
result = await platform.invokeMethod('reportErrorMethod',errorJson);
return Future.value(result);
}on PlatformException catch(e){
return Future.error(e.toString());
}
}

##需要引用iOS自定义framework库。
在podspec下， 通过s.subspec的方式，指定正确的framework路径
s.subspec 'xxxxFramework' do |ss|
ss.source_files = 'xxxxFramework/**/*.{h,m}'
ss.resource = 'xxxxFramework/**/*.{bundle,lic}'
ss.vendored_frameworks = 'xxxxFramework/xxxx.framework'
end
##需要引用iOS系统framework库。
在podspec下
#依赖系统Accelerate.framework
s.frameworks = 'Accelerate'
#依赖libc++.tbd , 去除lib前缀
s.libraries = 'c++'
