Keep getting error when trying to upload image to Firebase Storage-CodePudding

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):  ... 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.

Firebase Storage working on one application but not another

CodePudding user response：

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

CodePudding user response：

I have the similar problem and it solve like this.

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