Not a bug. Query parameters keys are supposed to be unique.

Hello @animator !!!!

With reference to some resources I would like to clarify what I was trying to point out:

1. MDN docs
   *Here with proper code snippet examples it is shown that how 'getAll()' method returns all the values associated with a given
   search parameter as an array. (JS)

2. Stackoverflow
   *Correct way to pass multiple values for the same parameter name.

3. In the following example for same named input, while selecting all the checkbox, console shows 'stocks=google&stocks=meta&stocks=microsoft'
   

Since both the server can read it and browser can produce it, thus to test the server side script, we should have the functionality in API Dash too.

@royshruti Thanks for providing the explanation & relevant links.
I am reopening this issue.

@animator For this to work we will need to update the expectation for codegen request models which are explicitly set to override here.

/// GET request model with override query params
const requestModelGet3 = RequestModel(
  id: 'get3',
  url: 'https://api.apidash.dev/country/data?code=US',
  method: HTTPVerb.get,
  requestParams: [
    NameValueModel(name: 'code', value: 'IND'),
  ],
);

@animator I have fixed this issue.. are there any tests you want me to perform before opening a PR?..
I will start working on #166 after this. The response had all ids i entered..

Code from view Code -
curl --url 'https://jsonplaceholder.typicode.com/posts?id=2&id=1&id=4&id=10'

also i am not the one being Loyal to a single language (Multilingual). I can also upgrade codegen for other languages to handle multiple same params.. It would take only a day or two.This will also help me revise many things.
Also in the codegen .. which is more preffered?

query params having only the added params

final response = await dio.Dio().get(
'https://jsonplaceholder.typicode.com/posts?id=7',
queryParameters: queryParams,
);

or queryparams having all the params

final response = await dio.Dio().get(
'https://jsonplaceholder.typicode.com/posts',
queryParameters: queryParams,
);

You have to ensure existing tests are corrected and new tests are added for this feature.
The codegen should work correctly for all the languages for this change.

I'll make sure of it
