DeviceEventEmitter not working in release version of the app

[shriyash-joinroy]

Description

DeviceEventEmitter.addListener is not working in release version, but works completely fine in the debug version of the app.
When added a adblogcat command to observe the event emission from the native code, we can see that data is emitted from the native side of the app, but fails to capture in react side.

Steps to reproduce

1. Add useEffect in the app.js file to listen for the event.
   useEffect(function() {
   let deferredLinkSubscription = null

   // Adding event listener to handle deferred links
   if (Platform.OS === 'android') {
   deferredLinkSubscription = DeviceEventEmitter.addListener(
   'InstallReferrer',
   function(data) {
   handleDeferredLinkUrl(data)
   }
   )
   }

   return () => {
   // Clean up the event listeners on unmount
   deferredLinkSubscription?.remove?.()
   }
   }, [])

I downloaded your repository and tested your code. In debug mode, it didn't work (at least not here).
I believe the issue is that React Native hasn't fully initialized the context yet (i.e., ReactContext hasn't been created), so you won't be able to emit the event to JavaScript. This happens when getReactContext() returns null, which means React Native isn't ready to receive events.

It's not much, but I hope I was able to help in some way.

native log that interests you (in debug and before start react context)

2025-01-04 22:18:20.799 25150-25187 InstallReferrer com.reproducerapp I ReactContext not ready. Queuing referrer.
2025-01-04 22:18:20.799 25150-25187 InstallReferrer com.reproducerapp I ReactContextListener added to handle referrer.

I somehow worked it out using NativeEventEmitter in React Native and adding up the 3s delay on kotlin side to send the referrer argument.
