ZonedFuture<T> class

A wrapper around an existing Future that processes all events received within a specific zone, instead of the default behavior of processing them in the zone that the then originated.

This can be used to retain the Future API without causing frameworks like Angular to capture events.

A simple example: void example() { var future = new Future.value(1); var frameworkZone = Zone.current.fork(); frameworkZone.run(() { expect(Zone.current, frameworkZone); }); var outerZone = Zone.current; future = ZonedFuture(future, outerZone.run); frameworkZone.run(() { future.then((_) { expect(Zone.current, outerZone); }); }); }
