cancelOperation method

Future<void> cancelOperation(
  1. CancelOperationRequest request
)

Starts asynchronous cancellation on a long-running operation. The server makes a best effort to cancel the operation, but success is not guaranteed. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED. Clients can use Operations.GetOperation or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an Operation.error value with a google.rpc.Status.code of 1, corresponding to Code.CANCELLED.

Throws a http.ClientException if there were problems communicating with the API service. Throws a StatusException if the API failed with a Status message. Throws a ServiceException for any other failure.

Implementation

Future<void> cancelOperation(CancelOperationRequest request) async {
  final url = Uri.https(_host, '/v1/${request.name}:cancel');
  await _client.post(url, body: request);
}
