forTarget method Null safety

Stream<T> forTarget (
  1. EventTarget? e,
  2. {bool useCapture = false}
)

Gets a Stream for this event type, on the specified target.

This will always return a broadcast stream so multiple listeners can be used simultaneously.

This may be used to capture DOM events:

Element.keyDownEvent.forTarget(element, useCapture: true).listen(...);

// Alternate method:
Element.keyDownEvent.forTarget(element).capture(...);

Or for listening to an event which will bubble through the DOM tree:

MediaElement.pauseEvent.forTarget(document.body).listen(...);

Implementation

Stream<T> forTarget(EventTarget? e, {bool useCapture: false}) =>
    new _EventStream<T>(e, _eventType, useCapture);
