# removeErrorListener method Null safety

void removeErrorListener (

1. SendPort port

)

Stops listening for uncaught errors from the isolate.

Requests for the isolate to not send uncaught errors on `port`. If the isolate isn't expecting to send uncaught errors on `port`, because the port hasn't been added using addErrorListener, or because it has already been removed, the request is ignored.

If the same port has been passed via addErrorListener more than once, only one call to `removeErrorListener` is needed to stop it from receiving uncaught errors.

Uncaught errors message may still be sent by the isolate until this request is received and processed.

## Implementation

    external void removeErrorListener(SendPort port);
