Trigger new OutlinedTextField when the first one is filled

Question

I am trying to achieve the creation of a user questionnary. So I have one input text field and I want to add more if the first one is filled with text.

Here my compose function to display the input field.

@Composable
private fun displayQuestion(number: String) {
    var question by remember { mutableStateOf("")}
    OutlinedTextField(
        value = question,
        onValueChange = {
            question = it
        },
        label = { Text(stringResource(R.string.question) + " n°$number") }
    )
    if (question !== "") {
        lastQuestionNumber += 1
    }
}

I can't figure out how to call this one if the question variable is different from "".
