What is the best way to initialize a variable with the Selenium's FindBy annotation in Kotlin?

Something like

@FindBy(id = "example")
private lateinit var button: WebElement

or

@FindBy(id = "example")
private val button: WebElement? = null

or

@FindBy(id = "example")
private var button: WebElement? = null

or something else?

Note that all the previous methods works perfectly.

The second option likely will not work, because the val is already initialized to null and cannot be changed.

I believe using the lateinit is the way to go in this case. It's meant for this purpose mainly.

You want late init because if the annotation fails to find it you will have a more understandable exception rather than null pointer exception
