How to know when a Composable like TextField gains focus?

Question

I want to trigger a function upon my TextField's focus-gain, but I am unable to find something like a listener.

I don't think using ```Modifier.focusable()``` on a ```TextField``` would be an appropriate choice, since it is already focusable. — Richard Onslow Roper, Jul 20 '21 at 13:32

You can use the onFocusChanged modifier

TextField(
    value = text,
    onValueChange = { text = it},
    modifier = Modifier.onFocusChanged {
        if (it.isFocused){
            //...
        }
    }
)
