When I checked the source code from the Rapid Scada, the GetCurData API had no parameter for colNames. (am I right? TT;)
so.. I think if you want to use colNames, you have to create a function for finding cnlNumber by Name.
In my case, my app loaded all databases that contain all cnl numbers and each tag name and I created a function for searching from that database cnlnumber by tagname.

I solve the problem.
I share the dart code. I will be glad if someone will modify it to a better code.

import 'package:dio_cookie_manager/dio_cookie_manager.dart';
import 'package:flutter/foundation.dart';
import 'package:cookie_jar/cookie_jar.dart';
import 'package:dio/dio.dart';
class InterfaceApi{
  InterfaceApi();
  late CookieJar cookies;
  late Dio dio;
  static var webSvrUrl = "http://192.168.35.145:10008";

  Future<void> writeResponse(Response response) async{
    final responseString = response.data.toString();
    if(responseString.isNotEmpty){
      if (kDebugMode) {
        print("RESULT[$responseString]");
      }
    }
  }

  Future<bool> webSvrLogin() async{
    bool result = false;
    cookies = CookieJar();
    dio = Dio(BaseOptions(baseUrl: webSvrUrl,responseType: ResponseType.json))
      ..interceptors.add(CookieManager(cookies));

    var loginResponse = await dio.post(
      '$webSvrUrl/Api/Auth/Login',
      data: { 'username': "admin", 'password': "12345"},
    );
    if(loginResponse.statusCode == 200){
      var loginResult = LoginResult.fromJson(loginResponse.data);
      result = loginResult.status;
      if (!result) {
        if (kDebugMode) {
          print('Result [${loginResult.msg}]');
        }
        result = false;
      }
    }else{
      if (kDebugMode) {
        print('Status Code :[${loginResponse.statusCode}]');
      }
      result = false;
    }
    return result;
  }

  Future<dynamic> webSvrReadSingleData(int tagId) async{
    var requestData = await dio.get("$webSvrUrl/Api/Main/GetCurData?cnlNums=$tagId");
    await writeResponse(requestData);
  }

  Future<bool> webSvrWriteSingleData(int tagId, double value) async{
    bool result = true;
    var response = await dio.post(
      "$webSvrUrl/Api/Main/SendCommand",
      data:{
        "cnlNum":"$tagId",
        "cmdVal":"$value"
      }
    );
    if(response.statusCode == 200){
      result = true;
    }else{
      result = false;
    }
    return result;
  }

}

class LoginResult {
  late bool status;
  late String msg;

  LoginResult({required this.status, required this.msg});

  factory LoginResult.fromJson(Map<String, dynamic> json) {
    return LoginResult(
      status: json["ok"] as bool,
      msg: json["msg"] as String,
    );
  }
}

This article is very helpful.
I also success login in by using REST API.
however I try to get and write data from Rapid Scada, but it’s not working the response statusCode is 401. how can I solve it?
