# addEventListener method

void addEventListener(

1. String type,
2. EventListener? listener, [
3. bool? useCapture

])
override

## Implementation

    void addEventListener(
      String type,
      EventListener? listener, [
      bool? useCapture,
    ]) {
      // Messages posted to ports are initially paused, allowing listeners to be
      // setup, start() needs to be explicitly invoked to begin handling messages.
      if (type == 'message') {
        _start();
      }

      super.addEventListener(type, listener, useCapture);
    }
