Is there a workaround for this issue?

class MyClass {
    var a: Int
    
    init {
        computeA()
    }

    private fun computeA() {
        a = 5
    }
}

The compiler complains that I have to initialize

a

, apparently it can't tell

computeA()

does initialize it.

@karelpeeters use

lateinit var

modifier

I can't believe I didn't think of that! I've been abusing

lateinit

a bit lately so I forgot it has legitimate use cases too 😒imple_smile:.

To be honest, this doesn't sound like a legitimate use-case for lateinit. Why not

var a = computeA()

?

Because I computeA() will be called from a lot of other setters. Basically is the result of an expensive calculation on a couple of other variables, and I want to reduce boilerplate.

Use lazy

Does lazy have an invalidate method or something? I want the field to change as others change as well.

Ok, Then lateinit seems fine 🙂

Check your custom setters. They won't assign a new value to property. Better use

var position by Delegates.observable(position) { prop, old, new -> updateView() }
