Auth not working in FirebaseStorage Flutter

Question

I am trying to upload a picture to Firebase storage in a Flutter app. The error message I got back is that the User don't have the permission to Upload. In my Storage rules the permission is set to read and write when auth != null. I can load images from the Storage with the download url. Also I print out the FirebaseAuth current user and it is set. If i set the Firebase Storage Rules to allow everything (without Auth) it works.

Do I need to exlicitly pass the auth user somewhere? The auth is handled by the provider package within the app.

Error:

Code:

Future<void> changeProfilePicture(File _image, User user) async {
    print(await FirebaseAuth.instance.currentUser());
    final StorageReference _storageReference =
        FirebaseStorage().ref().child(user.id);
    final StorageUploadTask _uploadTask = _storageReference.putFile(_image);
    StorageTaskSnapshot snap = await _uploadTask.onComplete;
    String downloadUrl = await snap.ref.getDownloadURL();
    print(downloadUrl);
    user.setProfilePictureURL(downloadUrl);

    Firestore.instance
        .collection('users')
        .document(user.id)
        .setData(user.toMap());
  }

Firebase Storage Rules;

service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
      allow read, write: if auth != null;
    }
  }
}

  intl: ^0.16.0

according to the Firebase error page does the error code means that the Sender ID is different to the token ID. I tried different User Accounts its for all the same result.

SENDER_ID_MISMATCH (HTTP error code = 403) The authenticated sender ID is different from the sender ID for the registration token.

Try changing

 final StorageReference _storageReference = FirebaseStorage().ref().child(user.id);

To

final StorageReference _storageReference = FirebaseStorage.instance.ref().child(user.id);
