Suggested Question

How can i make a MediaItem list from Json file? or do i need always to hard code all the MediaItems?
Thank you in advance.

You can use the MediaItem.fromJson function. If you want to restore a JSON list you can try using map:

List<MediaItem> mediaItemList = jsonList.map<MediaItem>((json) => MediaItem.fromJson(json)).toList();

Speaking of which, this proposal is a great idea:

dart-lang/language#216

It's unfortunate that you currently can't do this:

jsonList.map(MediaItem.fromJson).toList()

which would be much more concise. I could actually change the fromJson constructor to instead be a static method, and then you'd be able to write code like that.

As to whether this question should be added to the FAQ, if I added general programming questions to the FAQ, that would make the document less useful for its intended purpose, and I do not intend to do so.
