this is an excerpt from https://developer.android.com/codelabs/kotlin-bootcamp-sams#1

import kotlin.reflect.full.*

class Plant{
    fun trim(){}
    fun fertilize(){}
}

fun testAnnotations(){
    val classObj = Plant::class

    for (m in classObj.declaredMemberFunctions){
        println(m.name)
    }
}

declaredMemberFunctions

is still unrecognized

Did you add a Gradle dependency on

kotlin-reflect

?

this is in the standard library though
