Not able to upload file to firebase storage in Flutter

i'm trying to do the upload of image files to the cloud firestore in firebase using flutter. i'm always getting the following error and I do not understand where the issue is.

FirebaseException ([firebase_storage/object-not-found] No object exists at the desired reference.)

console:

E/StorageException(10183): StorageException has occurred.
E/StorageException(10183): Object does not exist at location.
E/StorageException(10183):  Code: -13010 HttpResult: 404

Here is my code:

class DatabaseMethods {

  CollectionReference cartesPro =
      FirebaseFirestore.instance.collection('cartesPro');
  FirebaseStorage storage = FirebaseStorage.instance;

  Future<String> uploadFile(file) async {
    Reference reference = storage.ref().child('cartesPro/');
    print('REFERENCE: ${reference}');
    UploadTask uploadTask = reference.putFile(file);
    print('UPLOAD TASK${uploadTask.snapshot}');
    TaskSnapshot taskSnapshot = await uploadTask;
    return await taskSnapshot.ref.getDownloadURL();
  }

  void addFile(CartPro cartPro) {
    cartesPro.add({
      "cartUserId": cartPro.cartUserId,
      "cartTimestamp": FieldValue.serverTimestamp()
    });
  }
}

Log of reference and uploadTask snapshot:

I/flutter (10183): REFERENCE: Reference(app: [DEFAULT], fullPath: cartesPro)
I/flutter (10183): UPLOAD TASK: TaskSnapshot(ref: Reference(app: [DEFAULT], fullPath: cartesPro), state: TaskState.running)

Everything seems pretty fine to me but still I do always get that error! I'd be grateful for any kind of help!

First, make sure your firebase storage rules are correct.

Example:

rules_version = '2';
service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
      allow read, write;
      
    }
  }
}

Second, try pushing the data that comes as File as Uint8List.

Example:

Future<String> uploadFile(File file, String uid) async {
    Reference reference = storage.ref().child('cartesPro/').child(uid); //It's helpful to name your file uniquely
    Uint8List bytes = file.readAsBytesSync(); //THIS LINE
    var snapshot = await reference.putData(bytes); //THIS LINE
    return await snapshot.ref.getDownloadURL();
  }
