Properties are class members that hold values and define rules for reading and writing those values. In Kotlin, the properties of a class represent the current state of an instance of that class. A typical class with properties looks like this:
class Button {
var text: String = TODO()
var backgroundColor: Int = TODO()
var onClickListener: ((Button) -> Unit)? = null
}
We can use this class to create objects and set values for the text, backgroundColor, and onClickListener properties. A combination of these properties in one object represents the state of an instance of the Button class.
