addError method Null safety
- Object error,
- [StackTrace? stackTrace]
Sends or enqueues an error event.
Listeners receive this event at a later microtask. This behavior can be
overridden by using
sync controllers. Note, however, that sync
controllers have to satisfy the preconditions mentioned in the
documentation of the constructors.
