网络请求数据返回 json.decode 报Json Formatter错误

在封装网络库的的时候发现 底层 response.data['data']时候当是一个jsonarray时候竟然无法直接取出'data',"Stirng not subType of Index "错误，原因是 此时拿到的不是一个json数据，没有双引号的假json数据，但是在jsonobject却可以，解决如下

if(callBack !=null) {  String res2Json  = json.encode(response.data);  Map map=json.decode(res2Json);  callBack(map["data"]);}
