CoderObserver<T> class

CoderObserver is a utility class that allows non-widget listeners (e.g., services, background workers, etc.) to respond to state changes without rebuilding widgets.

It attaches to a CoderState and notifies all registered callbacks when the value changes.

Example usage:

final observer = CoderObserver(counterState);

observer.add((value) {
  print("Counter updated: $value");
});

// When no longer needed:
observer.dispose();
