Kotlin : Public get private set var

What is the correct way to define a var in kotlin that has a public getter and private (only internally modifiable) setter?

var setterVisibility: String = "abc" // Initializer required, not a nullable type
    private set // the setter is private and has the default implementation

See: Properties Getter and Setter

However, in case of constructor(s), if possible use val instead of var, otherwise, Kotlin constructors do NOT support "private set", and you would need to create separate property, and set that through constructor:

class MyClass(private var myConstructorArg: String) {
    var myPropery: String = myConstructorArg; private set
}

Public getter, private setter

You can easily accomplish this using the following approach:

var atmosphericPressure: Double = 760.0
    get() {
        return field
    }
    private set(value) { 
        field = value 
    }

Look at this post for details.
