is there a way to create a

Delegates.observable

of a read-only property? e.g.

data class Foo(bar:Boolean, car:Boolean)
val foo by Delegates.observable(Foo(false,false)){...}
foo.bar = true

Observable field cannot detect such changes and notify.

foo.bar = true

To do that bar must be Delegates.observable itself

hmm 😕 ty, I just found out from the docs

Maybe you could make the setter private though?

make the setter private though

But sample code itself is impossible, you cannot observe changes of nested property (foo.bar), you can observe changes of foo itself
