How to check if a lateinit variable is initialized in Kotlin?

Hello colleagues! I've been writing in Kotlin relatively recently and encountered a situation. I have a class where I use `lateinit var` for a property. It works, but I want to safely check if this property has already been initialized before accessing it. If I try to access an uninitialized `lateinit` variable, I get `UninitializedPropertyAccessException`, which breaks the program. Here's an example of my code: ```kotlin class MyApp { lateinit var user: User fun setup() { // Here user may or may not be initialized if (someCondition) { user = User("Alice") } } fun printUser() { // I want to check if user is initialized to avoid the error ```
