Firebase ile yeni çalışmaya başladım. çok ilginç bir hata alıyorum.
final Reference ref = await FirebaseStorage.instance.ref().child("deneme").child("resimler").child("kalfa");
UploadTask uploadTask = ref.putFile(_secilenresim);
var downloadUrl = await uploadTask.snapshot.ref.getDownloadURL();
debugPrint(downloadUrl.toString());
kodları ile kalfa isimli resmimi firebase’ e upload edebiliyor ve downloadUrl i alabiliyorum. AMA
`String imageFileName = DateTime.now().millisecondsSinceEpoch.toString();
final Reference ref = await FirebaseStorage.instance.ref().child(“deneme”).child(“resimler”).child(imageFileName );
UploadTask uploadTask = ref.putFile(_secilenresim);
var downloadUrl = await uploadTask.snapshot.ref.getDownloadURL();
debugPrint(downloadUrl.toString());`
yaparsam resmi yükeleyebildiğim halde DownloadUrl alamıyorum. konsolda hata mesajı olarak:

bunları alıyorum. burada imageFileName String olarak tanımlı olduğundan hata vermemesi gerekiyor. teknik olarak kalfa yazandan hiç bir farkı yok. bir de istenen referansta obje yok diyor. halbuki resim Firebase’ e kaydedildi. anlayamadım.
