Dialog destinations

In Android navigation, the term dialog destination refers to destinations within the app's navigation graph which take the form of dialog windows, overlaying app UI elements and content.

Because dialog destinations appear over hosted destinations that fill the navigation host, there are some important considerations regarding how dialog destinations interact with your NavController's back stack.

Dialog composable

To create a dialog destination in Compose, add a destination to your NavHost using the dialog() function. The function behaves essentially the same as composable(), only it creates a dialog destination rather than a hosted destination.

Consider the following example:

fun SettingsDialog(){
    // ...

fun MyApp() {
    val navController = rememberNavController()
    NavHost(navController, startDestination = "home") {
        composable("home") { Home(onNavigateToHome = { navController.navigate("home") }) }
        dialog("settings") { SettingsDialog(onNavigateToSettingsDialog = { navController.navigate("settings") }) }
  1. The start destination is the Home composable. Because it uses composable(), it is a hosted destination.
  2. The other destination is the SettingsDialog composable. Because the dialog() function adds it to the graph, it is a dialog destination. When the user navigates from Home to SettingsDialog, the latter appears over Home.
  3. Although SettingsDialog doesn't include a Dialog composable itself, because it is a dialog destination, the NavHost displays it within a Dialog.

Dialog destinations appear over the previous destination in the NavHost. Use them when the dialog represents a separate screen in your app that needs its own lifecycle and saved state, independent of any other destination in your navigation graph. You might prefer to use an AlertDialog or related composable if you want a dialog for a less complex prompt, such as a confirmation.

Kotlin DSL

If you are working with fragments and you are using the Kotlin DSL to create your graph, adding a dialog destination is very similar to when using Compose.

Consider how in the following snippet also uses the dialog() function to add a dialog destination that uses a fragment:

// Add the graph to the NavController with `createGraph()`.
navController.graph = navController.createGraph(
    startDestination = "home"
) {
    // Associate the "home" destination with the HomeFragment.
    fragment<HomeFragment>("home") {
        label = "Home"

    // Define the "settings" destination as a dialog using DialogFragment.
    dialog<SettingsDialogFragment>("settings") {
        label = "Settings Dialog"


If you have an existing DialogFragment, use the <dialog> element to add the dialog to your navigation graph, as shown in the following example:

<?xml version="1.0" encoding="utf-8"?>
<navigation xmlns:android="http://schemas.android.com/apk/res/android"


    <argument android:name="myarg" android:defaultValue="@null" />
