我是 jetpack compose 的新手，我真的很想知道如何消除可组合对话框。jetpack compose 中的对话框是否有像 dismiss() 这样的函数？

通过使用下面的代码，我无法关闭该对话框，无论是触摸外部还是按后退按钮。该对话框在视图层次结构的顶部仍然可见。`

@Composable
fun InfoDialog() {
    val shouldDismiss = remember {
        mutableStateOf(false)

                        textAlign = TextAlign.Center,
                        modifier = Modifier
                            .padding(top = 8.dp)
                            .fillMaxWidth(),
