Dart HTML: Clear onClick listeners on Button
With keeping track you probably mean
List<StreamSubscriptions> subscriptions = [];querySelectorAll("button.update-something").forEach((ButtonElement b) { subscriptions.add(b.onClick.listen((e) { // Do Stuff }));}I guess this is what you are looking for
querySelectorAll("button.update-something").forEach((ButtonElement b) { b.addEventListener('click', clickHandler);}void clickHandler(e) { // Do stuff}querySelectorAll("button.update-something").forEach((ButtonElement b) { b.removeEventListener('click', clickHandler);}
