is there a way to expose a MutableMap externally as a Map without using a "wrapper" member? i.e.

private val _data = mutableMapOf<Int, String>()
val data: Map<Int, String>
    get() = _data

If there is one, I haven't found it.

No, backing properties are how it is supposed to be done: https://kotlinlang.org/docs/reference/properties.html#backing-properties

[karelpeeters]

@Ruckus Are you sure that's about the same thing?

[Ruckus]

Yes...?

[karelpeeters]

Yeah NVM I got some terms mangled up my bad.

[Ruckus]

Ah, okay. I was worried I may have misread the question, despite the fact it's almost exactly the example in the docs 🙂
