Add support for async/future

[pepie]

Any plan to add support for async calls, or perhaps FutureBuilder?

Suppose I am getting a list of images from an api with
Future<List> loadData() async{
...
return List data;
}

Rather than having to specify itemCount, perhaps I could simply call:

new Swiper(
futureBuilder: (c, i){
....
}
)

Is there a way to do this now?
