Trying to replicate https://stackoverflow.com/questions/23112130/creating-an-instance-of-a-generic-type-in-dart:

typedef S ItemCreator<S>();
class PagedListData<T>{
  ...
  ItemCreator<T> creator;
  PagedListData(ItemCreator<T> this.creator) {

  }

  void performMagic() {
      T item = creator();
      ... 
  }
}

My version, with a map to get values:

typedef S ItemCreator<S>(Map map);

abstract class DataCacher<T> {
  var cacheddata;
  ItemCreator<T> creator;
  var offsetLoaded = new Map<int, bool>();
  final RepaintCallback callback;
  int _total = -1;

  DataCacher({this.callback, this.creator(Map map)}) {
    cacheddata = new Map<int, T>();
  }
