Is there any way to check if a variable is val/var?

[earroyoron]

For what? I dont imagine a use case for that

[Javier]

interactive course

No.
var/val is just a compiler directive to raise red flag when a 'val' is re-assigned a new value and to possibly do some optimizations.
For a 'val' or 'var' property, you may be able to figure it out; you can see if the property is a KProperty or KMutableProperty (not sure if i have the class-names correc there)

I assume the metadata annotation contains info on that

[Javier]

@streetsofboston I tried yesterday with KProperty and KMutableProperty but I didn't get it working

[streetsofboston]

What did you try?
You can either use reflection or obtain a method reference (which is basically a KProperty) to inspect a property's mutability. Then a is KMutableProperty should do the trick, or something very similar.

[Javier]

@streetsofboston I tried is KMutableProperty but it says KProperty is incompatible with String

[streetsofboston]

String?
Did you try something like this: loadedEmployee::firstName is KMutableProperty<*> (note the use of :: instead of .)

[Javier]

it works, thank you!
