Using loops with Futures in Dart
When you need to wait for multiple Futures to complete and you don't care about the order, you can use Future.wait():
Future.wait(files.map(functionThatReturnsAFuture)) .then((List response) => print('All files processed'));If order is important you can use Future.forEach() instead which waits for each Future to be completed before moving to the next element:
Future.forEach(files, functionThatReturnsAFuture) .then((response) => print('All files processed'));

HeavyList<File> abc = new HeavyList<File>([new File(), new File(), ]);abc.loop(new Duration(seconds: 1), (List<File> origin) {print(origin);}, (File item, Function resume) { //simulating an asynchronous call print(item); //move to next item resume();});
