Is there a way to add a custom apiTemplateFile if queryParams are present? [dart-dio-next]

Description

I am trying to add an additional apiTemplateFile when some queryParams are present for the api.

For example, in the case of petstore.yaml, this is what I want to do:

lib
    - src
        - api
            - pet_api.dart
            - pet_api_query.dart      // <----- New file
            - store_api.dart
            - user_api.dart        
            - user_api_query.dart     // <----- New file
        - model
            - api_response.dart
            - category.dart
            - date.dart
            - order.dart
            - pet.dart
            - tag.dart
            - user.dart
        - api.dart
        - serailizers.dart
    openapi.dart

I intend to place some Built classes like this in the *_query.dart (ideally in a different folder than api), but only for operations that contain at least one query parameter.

abstract class FindPetsByStatusQuery implements Built<FindPetsByStatusQuery, FindPetsByStatusQueryBuilder> {

    FindPetsByStatusQuery._();

    factory FindPetsByStatusQuery([void Function(FindPetsByStatusQueryBuilder) updates]) = _$FindPetsByStatusQuery;

    String? get status;

}

What I have tried so far

• I have tried adding in a conditional statement inside the fromOperation method, but it still does not behave any differently. Am I looking/editing in the wrong place?
• I also have a feeling that I should create a supporting file. But again I could not find any documentation on how to create a supporting file for every operation that contains a queryParam.

Any help would be appreciated.

Start by tracing how the dart-dio-next generator handles apiTemplateFile and the fromOperation method, then reproduce the request with petstore.yaml. Determine whether the generator can emit an additional file for each operation containing query parameters, and document the required template and output behavior as done.
