Hi Guys, please advice. I have a data class with this property val bankAccount: BankAccount? = null
When I parse it to DTO object, which takes bankAccount as String, I use bankAccount.toString() which, in case of null, ends up being “null” String on DTO object.
How should I approach it, so the value is actually null or property is omitted?

bankAccount?.toString() (with safe call operator) would return an actual null value if bankAccount is null itself

Thanks!
