防止通过伴奏库点击背景关闭底部工作表

Question

我已尝试从本文中进行伴奏库导航，并且我想防止当我单击底部工作表的背景（灰色区域）时关闭底部工作表并使其根本不可单击，我该如何实现这一点？

这是链接中的代码

@Composable
fun MyApp() {
    val navController = rememberNavController()
    val bottomSheetNavigator = rememberBottomSheetNavigator()
    navController.navigatorProvider += bottomSheetNavigator


    ModalBottomSheetLayout(
        bottomSheetNavigator = bottomSheetNavigator
    ) {
        NavHost(navController, startDestination = "home") {
            composable(route = "home") {
                Button(onClick = { navController.navigate("sheet") }) {
                    Text("Click me to see something cool!")
                }
            }
            bottomSheet(route = "sheet") {
                Text("This is a cool bottom sheet!")
                Button(onClick = { navController.navigate("home") }) {
                    Text("Take me back, please!")
                }
                Spacer(modifier = Modifier.padding(200.dp))
            }
        }
    }
}

ModalBottomSheetLayout该sheetState参数设置如下：

sheetState: ModalBottomSheetState = rememberModalBottomSheetState(ModalBottomSheetValue.Hidden)

您可以通过传递此参数来防止解雇行为，如下所示：

// This prevents dismissing the ModalBottomSheet
    val sheetState = rememberModalBottomSheetState(
        initialValue = ModalBottomSheetValue.Hidden,
        confirmStateChange = { false }
    )
