我决定使用他们自己的共享视图模型创建单独的功能。当只有一个 nav_graph 存在时，一切正常。但是在我将主图与主图和功能分开之后，所有的都崩溃了

我有 2 个导航图。

  1. 主要的 nav_graph
  2. 特征的第二张图

我正在尝试从第一张图导航到第二张图。没关系。应用程序工作正常。

但是当我尝试使用此代码获取共享 viewModel 时会出现问题。

    @IdRes navGraphId: Int,
    qualifier: Qualifier? = null,
    noinline parameters: ParametersDefinition? = null
): Lazy<VM>  = lazy{
    val store = findNavController().getViewModelStoreOwner(navGraphId).viewModelStore
    getKoin().getViewModel(ViewModelParameter(VM::class, qualifier, parameters, Bundle(), store, null))
}

我得到这个异常

 java.lang.IllegalArgumentException: No destination with ID 2131689472 is on the NavController's back stack. The current destination is Destination(com.bykhkalo.apps.walletapp:id/create_outgoing_fragment)

怎么了 ？

有我的导航图
