How do I stop listening to HTML events, in Dart?

Question

I am listening for click events like this:

element.onClick.listen((e) => doCoolStuff());

How do I stop listening?

Answer 1

Because onClick returns a StreamSubscription, you can cancel() it to stop receiving events.

Here is an example:

import 'dart:async';

// ...

var subscription = element.onClick.listen((e) => doCoolStuff());
// later
subscription.cancel();
