# HttpClientResponse class Null safety

HTTP response for a client connection.

The body of a HttpClientResponse object is a Stream of data from the server. Listen to the body to handle the data and be notified when the entire body is received.

    new HttpClient().get('localhost', 80, '/file.txt')
         .then((HttpClientRequest request) => request.close())
         .then((HttpClientResponse response) {
           response.transform(utf8.decoder).listen((contents) {
             // handle data
           });
         });

Implemented types

## Methods

any(bool test(List<int> element)) → Future<bool>
  Checks whether `test` accepts any element provided by this stream. [...]
  inherited
asBroadcastStream({void onListen(StreamSubscription<List<int>> subscription), void onCancel(StreamSubscription<List<int>> subscription)}) → Stream<List<int>>
  Returns a multi-subscription stream that produces the same events as this. [...]
  inherited
asyncExpand<E>(Stream<E>? convert(List<int> event)) → Stream<E>
  Transforms each element into a sequence of asynchronous events. [...]
  inherited
asyncMap<E>(FutureOr<E> convert(List<int> event)) → Stream<E>
  Creates a new stream with each data event of this stream asynchronously mapped to a new event. [...]
  inherited
cast<R>() → Stream<R>
  Adapt this stream to be a `Stream<R>`. [...]
  inherited
contains(Object? needle) → Future<bool>
  Returns whether `needle` occurs in the elements provided by this stream. [...]
  inherited
detachSocket() → Future<Socket>
  Detach the underlying socket from the HTTP client. When the socket is detached the HTTP client will no longer perform any operations on it. [...]
distinct([bool equals(List<int> previous, List<int> next)]) → Stream<List<int>>
  Skips data events if they are equal to the previous data event. [...]
  inherited
drain<E>([E? futureValue]) → Future<E>

  inherited
elementAt(int index) → Future<List<int>>
  Returns the value of the `index`th data event of this stream. [...]
  inherited
every(bool test(List<int> element)) → Future<bool>
  Checks whether `test` accepts all elements provided by this stream. [...]
