Defining size to a custom array type in Android Kotlin

Question

How to define size for any custom component based array like ImageView?

I've tried the following code with a type mismatch error,

    private var dots: Array<ImageView>? = null
    dots = arrayOfNulls<ImageView>(size)

Here's the actual Java code,

private ImageView[] dots;
dots = new ImageView[dotsCount];

You need to specify that the element type of the array is nullable:

private var dots: Array<ImageView?>? = null
