# addError abstract method

void addError(

1. Object error, [
2. StackTrace? stackTrace

])
override

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

This method 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]);
