Android 组成 Navigation 和 ViewModel 无限网络调用

Question

Currently I'm using compose with navigation and viewmodels. The code of my NavHost is the following

composable(MyRoute.name + "/{param}") { backStackEntry ->
                    val param = backStackEntry.arguments?.getString("id") ?: ""
                    val viewModel = hiltViewModel<MyViewModel>()
                    viewModel.setInitialParam(param)
                    viewModel.fetchDataFromNetwork()
                    MyComposable(
                        viewModel = viewModel
                    )
                }

The issue I'm facing is that viewModel.fetchDataFromNetwork() is called an infinite number of times (I guess it is recomposition) but how would I make the call once to fetch the data and then display it in the MyComposable

Use a LaunchedEffect to run your network call.
