Kotlin Property items should be initialized before get

    var items: Int by Delegates.notNull<Int>()

    db.collection("Testdatabase").get().addOnSuccessListener{ snap->
        items=snap.size()
    }
    Log.i("items",items.toString())

and it says

Property items should be initialized before get

I have to use 'items' variable as a size of the snapshot. I searched some google but I can't figure out.. Can any one help please?

That happens because your addOnSuccessListener takes some time to get data. So in this example, you need to put your log statement inside addOnSuccessListener and you will be fine
