EventObject class abstract

A base class for all framework-level events.

This class captures the origin of the event (_source) and the time it occurred (_timestamp). Subclasses typically define the specific type of event (e.g., context refresh, startup, shutdown).

Events are generally published and consumed within an application event system, allowing for decoupled communication between components.

Example

class ApplicationStartedEvent extends EventObject {
  ApplicationStartedEvent(Object source) : super(source);
}

final event = ApplicationStartedEvent(appContext);
print(event.getSource()); // appContext
print(event.getTimestamp()); // DateTime of creation
