java.lang.IllegalArgumentException：与请求 NavDeepLinkRequest 匹配的导航目的地

Question

错误：

java.lang.IllegalArgumentException: Navigation destination that matches request NavDeepLinkRequest{ uri=android-app://androidx.navigation/book_screen } cannot be found

导航根主机：

animatedCompose("${Graph.BOOK}/{id}",
arguments = listOf(
    navArgument("id"){
        type = NavType.LongType
        defaultValue = -1
    }
)
    ){
    val id = it.arguments?.getInt("id") ?: -1
    val actionText = if(id != -1) "Save" else "Add"
    val title = if(id != -1) "Edit Book" else "Add New Book"
    BookScreen(navHostController, title=title, actionText=actionText)
}

从另一个屏幕内：

 Scaffold(
        floatingActionButton = {
            FloatingActionButton(onClick = {
                rootNavHostController.navigate(Graph.BOOK)
            }) {
                Icon(Icons.Filled.Add,null)
            }
        }

我认为，您可以将{id}可选参数作为参数。但是，不确定为什么现在不起作用。

通过这样做解决了它：

animatedCompose("${Graph.BOOK}/?id={id}",
  arguments = listOf(
            navArgument("id"){
                type = NavType.IntType
                defaultValue = -1
            }
        ){}
