I'm trying to implement a compiler plugin to convert code from

@Repr
value class DateT {

}

to

@JvmInline
value class DateT(val repr: REPR) {

}

I've successfully implement the add @JvmInline annotation, and adding a value parameter in constructor, but I'm having trouble declaring the val repr.
Should I do it in fir generation? or fir transform? I got VALUE_CLASS_CONSTRUCTOR_NOT_FINAL_READ_ONLY_PARAMETER, did I miss something, how do I properly create a property in Fir so it is a correct inline value class?
