@remonh87 this change was on purpose as Stripe changed it as well. Can you double check?

@jonasbark yes I see that on Android but not on iOS as there it is still oncardchange:

func onCardChange(_ arguments: Dictionary<AnyHashable, Any>?) {
    channel.invokeMethod("onCardChange", arguments: arguments)
}

so shall we then fix it in Swift in our factory to keep it consistent?
