broadcast method
void
broadcast([
- T? args
Broadcast this Event to subscribers, with an optional EventArgs derived argument.
Ignored if no handlers (subscribers). Calls each handler (callback) that was previously added to this Event.
// Example
// Without an [EventArg]
onValueChanged.broadcast();
// With an argument [EventArg]
onValueChanged2.broadcast(ChangedValue(3.14159));
Implementation
void broadcast([T? args]) {
for (var i = 0; i < _handlers.length; i++) {
_handlers[i].call(args);
}
}
