I initialize like this

await Firebase.initializeApp(
     options: DefaultFirebaseOptions.currentPlatform,
   );

   await Parse().initialize(
     "key",
     "url",
     debug: true,
     coreStore: await CoreStoreSharedPreferences.getInstance(),
   );

   ParsePush.instance.initialize(FirebaseMessaging.instance, parseNotification:
       ParseNotification(onShowNotification: (message) async {
     print(message);
   }));
   FirebaseMessaging.onMessage
       .listen((message) => ParsePush.instance.onMessage(message));

   FirebaseMessaging.onBackgroundMessage(onBackgroundMessage);

   currentUser = await ParseUser.currentUser();

   if (currentUser != null) {
     await initInstallation();

Future<void> initInstallation() async {
    final ParseInstallation installation =
        await ParseInstallation.currentInstallation();
    final ParseResponse response = await installation.create();
    print(response);
  }

when i do a fresh install i get java.lang.NullPointerException: Attempt to invoke virtual method 'java.io.File com.parse.ParsePlugins.getFilesDir()' on a null object reference however when i run the app a second time the error doesnt appear

i dont know it is a miss configration but install object is not saved in the database yet deviceToken is set and the object is well populated here is the log

These items you added in the manifest are for Parse Android, these items are not needed for Parse Flutter, please check the push notifications document again.
