Image URL from firebase storage to firestore - flutter

Question

this is how I upload images to firebase storage and get the Download URL in firebase Firestore. Everything works properly how ever I get the 1st URL but not the Second one.
Future<void> uploadImage2(image2) async {
setState(() {
isLoader2 = true;
});
final bytess = image2.readAsBytesSync();
var timeStamp = DateTime.now();
final metadata = firebase_storage.SettableMetadata(contentType: 'CarImage');
firebase_storage.UploadTask task = firebase_storage.FirebaseStorage.instance
.ref('Toyota-Images/$timeStamp/2.png')
.putData(bytess, metadata);
firebase_storage.TaskSnapshot downloadUrl2 = (await task);
String url = (await downloadUrl2.ref
.getDownloadURL()); //this is the url of uploaded image
imageUrl2 = url;
setState(() {
isLoader2 = false;
});
}
Future<void> uploadImage3(image3) async {
setState(() {
isLoader3 = true;
});
final bytess = image3.readAsBytesSync();
var timeStamp = DateTime.now();
final metadata = firebase_storage.SettableMetadata(contentType: 'CarImage');
firebase_storage.UploadTask task = firebase_storage.FirebaseStorage.instance
.ref('Toyota-Images/$timeStamp.png')
.putData(bytess, metadata);
firebase_storage.TaskSnapshot downloadUrl3 = (await task);
String url = (await downloadUrl3.ref
.getDownloadURL()); //this is the url of uploaded image
imageUrl3 = url;
setState(() {
isLoader3 = false;
});
}

You can upload image to firebase as below
First of all you need to add this plugin in pubspec.yaml
firebase_storage: ^8.0.0
import 'package:firebase_storage/firebase_storage.dart' as firebase_storage;
Future<void> uploadFile(File _image) async {
setState(() {
isLoader = true;
});
final bytess = _image.readAsBytesSync(); //"_image" is your selected image or any other which you need to upload
var timeStamp = DateTime.now();
final metadata = firebase_storage.SettableMetadata(contentType: 'image/jpeg');
firebase_storage.UploadTask task = firebase_storage.FirebaseStorage.instance
.ref('cover_photo/'+timeStamp.toString()+'insp_cover_photo.png').putData(bytess,metadata);
firebase_storage.TaskSnapshot downloadUrl = (await task);
String url = (await downloadUrl.ref.getDownloadURL()); //this is the url of uploaded image
setState(() {
isLoader = false;
});
}
Let me know if you have any questions

You can do it using firebase_storage.
you can get url by using this function.
Future<String> uploadFile(File _imageFile) async {
String fileName = DateTime.now().millisecondsSinceEpoch.toString();
Reference reference = FirebaseStorage.instance.ref().child(fileName);
UploadTask uploadTask = reference.putFile(_imageFile);
return uploadTask.then((TaskSnapshot storageTaskSnapshot) {
return storageTaskSnapshot.ref.getDownloadURL();
}, onError: (e) {
throw Exception(e.toString());
});
}
