Keep getting error when trying to upload image to Firebase Storage

Here is my code:

 Future selectFile() async {
    final result =
        await ImagePicker.platform.pickImage(source: ImageSource.gallery);

    if (result == null) return;
    final path = result.path;

    setState(() {
      file = File(path);
    });
  }

  Future uploadFile() async {
    if (file == null) return;

    final fileName = file!.path.split("/").last;
    final destination = "test/";

    Storage.uploadFile(destination, file!);
  }

import 'dart:io';

import 'package:firebase_storage/firebase_storage.dart';

class Storage {
  static Future<void> uploadFile(String destination, File file) async {
    try {
      final ref = FirebaseStorage.instance.ref().child(destination);

      await ref.putFile(file);
    } on FirebaseException catch (e) {
      print(e);
    }
  }
}

I can’t seem to work out why exactly the code does not upload a photo, I have changed the rules in firebase but to no avail and the folder is called test so if anyone could suggest what I do or how to test my firebase storage, that would be a great help. Thanks in advance.

I keep getting this error when I call uploadFile:

E/StorageException(27972):  at com.google.firebase.storage.network.NetworkRequest.performRequest(NetworkRequest.java:272)

E/StorageException(27972):  ... 5 more
I/flutter (27972): [firebase_storage/object-not-found] No object exists at the desired reference.

Firebase rules are:

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

UPDATE

I created a new flutter application with the above code and just two buttons, so it seems it may be a flaw in my other application’s dependencies or something like that rather than the code. Thank you to everyone who helped once I figure out how to get it to work on my original application I will update.

    I have the similar problem and it solve like this.

    await ref.putData(await file.readAsBytes());

    The reference you created should look like this now you added ref to the destination. please try the following

    final ref = FirebaseStorage.instance.ref().child('$destination/${file.name}.${file.extension}');

    EDIT

    final ref = FirebaseStorage.instance.ref();


final uploadTask = ref.child('$destination/${file.name}.${file.extension}')
    .putFile(file, SettableMetadata(
    contentType: "image/jpeg",
  ));

    Edit1*

    Remove static from here.

    import 'dart:io';

import 'package:firebase_storage/firebase_storage.dart';

class Storage {
  Future<void> uploadFile(String destination, File file) async {
    try {
      final ref = FirebaseStorage.instance.ref().child(destination);

      await ref.putFile(file);
    } on FirebaseException catch (e) {
      print(e);
    }
  }
}

    When you wish to upload first make a reference

    Storage _storage = Storage();
_storage.uploadFile(destination, file!);

    This should work as expected

    enter code here

    final firebaseStorage = FirebaseStorage.instance.ref();

    // late var user = _auth.currentUser;

    var postid = Uuid().v1();

    Future postData( imageFile) async {

    enter code here
print("******************** ${timeles}");
final user = await _auth.currentUser;
enter code here
UploadTask uploadTask =
    firebaseStorage.child("post_$postid.jpg").putFile(imageFile) ;
TaskSnapshot f = await uploadTask.timeout(Duration(seconds: 50));
TaskSnapshot taskSnapshot = await uploadTask.timeout(Duration(seconds: 20));
enter code here
String Iurl =( await taskSnapshot.ref.getDownloadURL()).toString();


enter code here
postref.doc(user?.uid).collection("posts").doc(postid).set({
  "postid": postid,
  "ownerid": user?.uid,
  "email": user?.email,
  "price": _price.text.trim(),
  "phone": _phoneControlle.text.trim(),
  "name": _name.text.trim(),
  "location": _title.text.trim(),
  "dateprice": timeles.toString(),

    "mediaurl": Iurl,

    });
return Iurl;
