Hi, I wrap my head around a problem. I want to build a data class in relation to specific conditions. For instance:
```data class Test(val test1: Int, val test2: Int)```
This would be the base and if a specific condition is satisfied:
```data class Test(val test1: Int, val test2: Int, val test3: Int)```
I could create 2 separate data classes but then I always have to pass both and I'd like to deal only with one data class. Does someone has an idea?

I think you can make the third field nullable.

data class Test(val test1: Int, val test2: Int, val test3: Int? = null)

make third field optional by giving it a default value..

The problem is that it won't be just 1 field but rather 5-10 fields and there are more than 1 condition
