Is there anyway of fixing unresolved reference: until in android studio

Question

Whenever I run this code I keep getting errors that say unresolved reference: until. Please can anyone help me out with this?

for (row in 0 until nSquares) {
    counter = if (row and 1 == 0) {
        paint!!.setARGB(
                   200 ,
                   SquareOne[0],
                   SquareOne[1],
                   SquareOne[2])
    }
    ...

Answer 1

Add this in your gradle app level on top inside plugin

apply plugin: 'kotlin-android-extensions'

Or in new version

id:'kotlin-android-extensions'

Or you can also use it for like this

for (row in 0..nSquare){
}
