GetItem, IEnumerable<T>, and nulls about blazorstorage HOT 2 CLOSED

Hey @scottsauber great idea!
But i see some potential issues with it, the expectation from the signature is that it should return null in this case.
Also one could really want to know if it is null or an empty collection.
But how about another overload, that allows to specify a default value that should be returned in case of a null or empty value?

Something like this
Storage.GetItem("Key", new List<ToDoItem>())
or
Storage.GetItem("Key", () => new List<ToDoItem>())

Would that be something of interest to you?

Another idea for your scenario might be to create an extension with exactly your logic in it.

public static T GetItemOrNew<T>(this Storage storage, string key)
    where T : new()
{
    var json= storage.GetItem(key);
    if (string.IsNullOrEmpty(json))
    {
            return new T();
    }
    return Json.Deserialize<T>(json); 
}

Thanks for the support, let me know how it went! And if there is video coverage i would be interested to see it!

True, I guess you may treat no key exists in local storage differently than "the key exists, but nothing is in here."

Sounds good, I'll let you know on the video. It was recorded, so I assume it'll be up at some point.

Basically demo'd using it with ToDoMVC and this repo: https://github.com/scottsauber/BlazorToDoMVC
