# abort method Null safety

1. @Since("2.10")

void abort (

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

)
@Since("2.10")

Aborts the client connection.

If the connection has not yet completed, the request is aborted and the done future (also returned by close) is completed with the provided `exception` and `stackTrace`. If `exception` is omitted, it defaults to an HttpException, and if `stackTrace` is omitted, it defaults to StackTrace.empty.

If the done future has already completed, aborting has no effect.

Using the IOSink methods (e.g., write and add) has no effect after the request has been aborted

    HttpClientRequst request = ...
    request.write();
    Timer(Duration(seconds: 1), () {
      request.abort();
    });
    request.close().then((response) {
      // If response comes back before abort, this callback will be called.
    }, onError: (e) {
      // If abort() called before response is available, onError will fire.
    });

## Implementation

    @Since("2.10")
    void abort([Object? exception, StackTrace? stackTrace]);
