Hi there,
I noticed that inside the
addListener, if someone trying to listen to an event which is already listened before, which will causeRNTGlobalEventEmitter.addObserver(eventName);run one more time, which is unnecessary to register an native listener at NSNotificationCenter.Whats more, I added
removeListenderByIdmethod, because sometimes to deal with scope issues, you need to passing a closure / code block to theaddListener, which makesremoveListenerharder. WithremoveListenderById, you only need to passing the event name and the reference ID, which can get fromaddListener.
