Starting from Version firebase_storage 5.0.1:

You have to do the following:

FirebaseStorage storage = FirebaseStorage.instance;
Reference ref = storage.ref().child("image1" + DateTime.now().toString());
UploadTask uploadTask = ref.putFile(_image1);
uploadTask.then((res) {
   res.ref.getDownloadURL();
});

StorageReference class has been removed and now you have to use the class Reference. UploadTask extends Task, which also implements Future. Therefore all the methods that are in the class Future can be used on the class UploadTask.

So to get the url of the image, you need to use the then() method which registers a callback to be called when this future completes.
