ApplicationEvent class abstract
A base class for application-specific events within the JetLeaf framework.
Extends EventObject and allows capturing the event creation time using either the system clock or a custom clock function.
Subclasses of ApplicationEvent are used to represent meaningful events in the lifecycle of an application, such as context initialization, refresh, shutdown, etc.
Example
class ContextRefreshedEvent extends ApplicationEvent {
ContextRefreshedEvent(Object source) : super(source);
}
final event = ContextRefreshedEvent(appContext);
print(event.source); // appContext
print(event.timestamp); // time of creation
