on method

void on(
  1. Events event,
  2. Function handler
)

Subscribes handler to event.

Handlers may declare fewer parameters than the event provides; the emitter calls each one with exactly the number it declares.

Implementation

void on(Events event, Function handler) {
  _appHandlers.add(MapEntry(event, handler));
  _eventEmitter.on(event.parseToString(), handler);
}
