Build Fails due to flutter_nearby_connections package

As per the history of the project, p2p_client_dart was not a null safe package and hence a new package called flutter_nearby_connections was used.
Now build fails since task ':app:checkDebugDuplicateClasses' fails and I figured out that the error is due to flutter_nearby_connections package probably because it built using an older Kotlin Version. So, I removed the package and tried building it and this time the build was successful.
Hence, it would be better to replace the flutter_nearby_connections package with nearby_connections which is a new and updated package.
