Android导航组件从homefragment关闭应用程序

Question

如何在到达 HomeFragment(startDestination)时清除所有堆栈，当用户通过导航组件按下 homeFragment 时，我想关闭应用程序。

 <navigation xmlns:android="http://schemas.android.com/apk/res/android"
                xmlns:app="http://schemas.android.com/apk/res-auto"
                xmlns:tools="http://schemas.android.com/tools"
                app:startDestination="@+id/homeFragment">


        <fragment android:id="@+id/homeFragment"
                  android:name="ui.fragment.home.HomeFragment"
                  tools:layout="@layout/fragmet_home"
                  android:label="HomeFragment" 
                  app:launchSingleTop="true" 
                  app:popUpToInclusive="true">

            <action android:id="@+id/action_homeFragment_to_notificationFragment"
                    app:destination="@id/notificationFragment"
                    app:popUpTo="@+id/homeFragment"
                    app:enterAnim="@anim/pop_enter"
                    app:exitAnim="@anim/pop_exit"
                    app:popEnterAnim="@anim/right_in"
                    app:popExitAnim="@anim/right_out"/>
       </Fragment>

       <fragment  android:id="@+id/notificationFragment"
                  android:name="ui.fragment.notification.NotificationFragment"
                  tools:layout="@layout/fragment_notification"/>
 </navigation>

 @Override
public void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    OnBackPressedCallback callback = new OnBackPressedCallback(true) {
        @Override
        public void handleOnBackPressed() {
            getActivity().finishAndRemoveTask();
        }
    };
    requireActivity().getOnBackPressedDispatcher().addCallback(this,callback);
}
