onCancel method

  1. @mustCallSuper
void onCancel(
  1. Exception cancelException
)

Called when the attached token is cancelled.

It's not necessary to detach from the token in this method, as cancellation tokens detach from all cancellables automatically when cancelled.

Implementation

@mustCallSuper
void onCancel(Exception cancelException) {
  _attachedToken = null;
  _isCancelled = true;
}
