I have declared the `frameLayout` inside the onCreate method. I tried to create `var enableCheckBox: CheckBox` before declaring the frameLayout. But when i tried to access `enableCheckBox` in the rest of the onCreate method, it gave an error saying `Variable "enableCheckBox" must be initialized`

aakaashjois: you should use something like this:

class MyActivity : ... {

    lateinit var enableCheckBox: CheckBox

    override fun onCreate() {
         .....
        frameLayout {
              enableCheckBox = checkBox {
                    text = "Enable"
              }
         }
         ....
    }

}

you can use enableCheckBox as normal property, but you need to mark it lateinit as it isn't initialized in class constructor.

Thank you! I did not know about the `lateinit`. Since I am just using the variable inside the onCreate method, I thought I can declare it inside onCreate instead of global variable. But it looks like `lateinit` only works with global variable as of now.

You can also use `Delegates.notNull()` inside functions.

<@U0B99LPPW> I was not able to understand how `Delegates.notNull()` works :confused:
