flutter - 如何使用DIO设置 flutter POST方法？

Question

这是我的下面的代码，我被卡住了，请帮忙。如何使用DIO设置 flutter POST方法？

Map<String, dynamic> toJson() {
    return {
        'id': id,
         "name": name,
         "telNumber": telNumber,
         "email": email,
         "age": age
      };
   }

String postToJson(Post data){
      final dyn = data.toJson();
      return json.encode(dyn);
}

Future<http.Response> createPost(Post post) async {
          final response = await http.post(
               "$baseUrl/users",
              headers: {
                  "content-type": "application"
                    },
              body: postToJson(post));
              return response;
            }

 BaseOptions options = new BaseOptions(
     baseUrl: $baseUrl,
     connectTimeout: 10000,
     receiveTimeout: 10000,);
final dioClient = Dio(options);
try{
   final response = await dioClient.post("/users", data: FormData.fromMap(
      postToJson(post))
    ),);
   return response;
} catch (e) {
  throw (e);
}

将此代码放入函数中
