Drop Entity In World

I'm trying to drop an item in the World. Similar to Bukkit's dropItemNaturally. I'm pretty sure I have to do

Code:

$this->api->entity->drop(new Position($x, $y, $z));

However, this function also requires an Item. How would I make this? Can I get the item from a $data variable in my event?

Is $id, $meta, and $amount integers?

Calling in static manner is better.
