Why ransank doesn't work with flutter chopper?

Can ransank work with flutter chopper?

My flutter project using chopper to call api server, which written using Rails.

   @Post(path: "orders_list")
      Future<Response> getOrderList(@Field('token') String authToken,  @Field('q[flow_gteq_any]') int flow,
            @Field('q[flow_lteq_any') int flow2);

I want server return data based on flow_gteq_any and flow_lteq_any, but it returns all data to me instead.
