title: channel or mutablesharedflow , which one is a better replacement for deprecated localbroadcastmanager
body: <p>In the past, I was using <code>LocalBroadcastManager and EventBus</code> in my chat and taxicab applications which are now either deprecated or not recommended using them.</p>
  <p>I intend to replace them with new data structures like <code>mutablesharedflow or channel</code>,
  i want to know which one is better matched with my case? or maybe another data structure?</p>
