I try to get image from firebase storage.

  static Future<String?> getImage(String? imgName) async{

    final storageRef = FirebaseStorage.instance.ref();

    final pathReference = storageRef.child("$imgName.png");

    print(pathReference.getDownloadURL());

  }

But I have a problem

Error getting App Check token; using placeholder token instead. Error: com.google.firebase.FirebaseException: No AppCheckProvider installed.

I use firebase auth and I think that here is a problem with it
I tried to connect App Check but it had all invalid request
here is a my requests with App Check

I guess I need to add some token
here but I don’t know where I should get this token
