# addError method Null safety

void addError (

1. Object error,
2. [StackTrace? stackTrace]

)
inherited

Passes the error to the target consumer as an error event.

This function must not be called when a stream is currently being added using addStream.

This operation is non-blocking. See flush or done for how to get any errors generated by this call.

## Implementation

    void addError(error, [StackTrace? stackTrace]) {
      _sink.addError(error, stackTrace);
    }
