Tracks async callbacks (e.g. microtask, Future, Stream, Timer) and indicates when any of these has completed their executions. It can be used to track and react on async event chains.

Clients of the AsyncTracker either listen on the stream or they can add or remove listeners that receive these events.

A simple usage example:

import 'package:async_tracker/async_tracker.dart';

main() {
  final tracker = new AsyncTracker();
  tracker.addListener(() {
    print('tracker has detected an execution');
  });

  tracker.run(() {
    // do any async stuff
  });
}
