JEffect<V> class abstract

Base class representing a one-time UI side effect.

A JEffect encapsulates transient operations that the UI should handle, such as showing a dialog, navigating to another screen, displaying a snackbar/toast, or triggering animations.

These actions do not alter the main application state and are meant to be handled only once by the UI layer.

V represents the type of value that may be returned from the UI when the side effect completes (e.g., user confirmed/canceled a dialog).

Example:

class ShowDialogEffect extends JEffect<bool> {
  final String title;

  ShowDialogEffect(this.title);
}
