I'm wondering if contracts would help to get rid of that !!:

dtos.filter { it.field != null }
    .map { OtherDto(it.field!!, it.otherField, it.anotherField) }

[wck]

it will, but I just what to know how can that even happen?

It will not

Instead you can combine both filter and map in single mapNonNull and just do check there.
It's also more efficient
