Why having setText() on text field Kotlin compiler compains?

Question

private class FakeCardDrawable constructor(
    context: Context) : CardDrawable(context) {
    var text: String? = null
    var backgroundColor = 0
    var textColor = 0


    override fun setColors(
        backgroundColor: Int, textColor: Int, animate: Boolean
    ) {
        this.backgroundColor = backgroundColor
        this.textColor = textColor
    }

     fun setText(text: String) {
        this.text = text
    }
}

It complains saying "Platform declaration clash: The following declarations have the same JVM signature(setText..)

`setText()` method is auto-generated by kotlin compilers, you don't need the overhead to implement them manually. — Animesh Sahu, Apr 20 '20 at 08:39

Because your var text and your function setText() are both translated into JVM to a public method named setText().

To avoid platform declaration clash you have 3 options here:

Change the name of var text or the name of setText
Make var text with a private set:

var text: String? = null
  private set

Change the JVM name of the method:

@JvmName("myJvmName")
fun setText(text: String) {
    this.text = text
}
