firebase_storage/object-not-found No object exists at the desired reference-CodePudding

my code


Future<String> uploadFile(File _image) async {
  int uploadTimestamp = DateTime.now().millisecondsSinceEpoch;
  Reference ref = FirebaseStorage.instance.ref().child('posts/$uploadTimestamp');
  UploadTask uploadTask = ref.putFile(_image);
  final TaskSnapshot taskSnapshot = await uploadTask.whenComplete(() {});
  final url = await taskSnapshot.ref.getDownloadURL();

  return url;
}

firebase_storage: ^10.3.1
firebase_core: ^1.19.1

Error: [firebase_storage/object-not-found] No object exists at the desired reference.

CodePudding user response：

what are you trying to achieve. one suspeect here is youre not calling _image anywhere. Seem like youre trying to upload an int.

CodePudding user response：

You are not calling the

await ref.putFile(_image);

before the:

final TaskSnapshot taskSnapshot = await uploadTask.whenComplete(() {});

And then call:

await ref.getDownloadURL();

after the upload in order to get the download url.

and also try to listen to the different upload states like:

uploadTask.snapshotEvents.listen((TaskSnapshot taskSnapshot) {
  switch (taskSnapshot.state) {
    case TaskState.running:
      final progress =
          100.0 * (taskSnapshot.bytesTransferred / taskSnapshot.totalBytes);
      print("Upload is $progress% complete.");
      break;
    case TaskState.paused:
      print("Upload is paused.");
      break;
    case TaskState.canceled:
      print("Upload was canceled");
      break;
    case TaskState.error:
      // Handle unsuccessful uploads
      break;
    case TaskState.success:
      // Handle successful uploads on complete
      // ...
      break;
  }
});

This could be useful. I put in together this.

Future<String> uploadImageToDefaultBucket(File image) async {
    Reference firebaseStorageRef = FirebaseStorage.instance.ref("your-ref").child("your-path");
    UploadTask uploadTask = firebaseStorageRef.putFile(image);
    TaskSnapshot taskSnapshot = await uploadTask;
    return taskSnapshot.ref.getDownloadURL();
  }
