add method Null safety
- Event event
Notifies the Bloc of a new event
which triggers mapEventToState.
If close has already been called, any subsequent calls to add will
be ignored and will not result in any subsequent state changes.
Implementation
void add(Event event) {
if (_eventController.isClosed) return;
try {
onEvent(event);
_eventController.add(event);
} catch (error, stackTrace) {
onError(error, stackTrace);
}
}
