```
 abstract Unit onStateChanged(FlagsClientState newState)
```
    Called when the state of the FlagsClient changes.
    Important: This method is called synchronously while holding internal locks. Implementations should be fast and non-blocking. If you need to perform long-running operations (network calls, database queries, heavy computation), dispatch them to a background thread.
    Exception handling: Exceptions thrown from this method will propagate to the caller and may crash the application if not caught. Subsequent listeners will not be notified if an exception is thrown. Always catch and handle exceptions within your implementation to prevent crashes and ensure other listeners are notified.
    
    Parameters:
    
    newState - The new state of the client.
