cancel method
Cancels/aborts all pending requests on this controller. This will cause all requests to throw a CancelledException.
Optionally, a message
may be specified to provide a reason for the
cancellation that will be included in the exception. If no message is
specified, the default message is "Request cancelled".
Implementation
void cancel([final String message = 'Request cancelled']) {
for (final activeRequest in _activeRequests) {
activeRequest.cancel(message);
}
}
