Checking Online/Offline Status with Laravel Reverb Broadcasting for a Flutter API Backend

Hi everyone,

I'm working on a Laravel backend API that supports a Flutter app, and I'm using Laravel Reverb. I want to implement a feature similar to WhatsApp, where users can see whether another user is online or offline when viewing their profile.

My question is: Can this functionality be achieved using Reverb broadcasting channels? If so, what would be the best approach to implement this feature, considering that Laravel is solely serving as the API backend for a Flutter client?

Any guidance, code examples, or best practices would be greatly appreciated.

Thanks in advance!
