如何将请求焦点转移到 Jetpack compose 中的下一个文本字段

这段代码应该给出一个基本的想法。

代码

@Composable
fun OtpScreen() {
    val focusManager = LocalFocusManager.current
    val (digit1, setDigit1) = remember {
        mutableStateOf("")
    }

        mutableStateOf("")
    }
    val (digit3, setDigit3) = remember {
        mutableStateOf("")
    }
    val (digit4, setDigit4) = remember {
        mutableStateOf("")
    }
    LaunchedEffect(
        key1 = digit1,
    ) {
        if (digit1.isNotEmpty()) {
            focusManager.moveFocus(
                focusDirection = FocusDirection.Next,
            )
