Hello,
I'm working on analyzing class constructor parameters. When accessing those parameters via KSValueParameter class, I see that we have hasDefault property to tell if we have default value. How do you get the default value expression behind?

class A( val i : Int = 0 )

How to get the default value of "i" here?

ok, thanks 👍

There's a temporary workaround I've been using to accomplish this using if you add the KSP implementation and kotlin-compiler-embeddable as a library:

val KSPropertyDeclaration.defaultValue: String?
        get() = (this as? KSPropertyDeclarationParameterImpl)
            ?.ktParameter
            ?.defaultValue

Which returns the raw PSI expression of the default value

it is still hard to evaluate the psi expression on your side though.
