HttpClientResponse class Null safety

HTTP response for a client connection.

The body of a HttpClientResponse object is a Stream of data from the server. Use Stream methods like Stream.transform and Stream.join to access the data.

var client = HttpClient();
try {
  HttpClientRequest request = await client.get('localhost', 80, '/file.txt');
  HttpClientResponse response = await request.close();
  final stringData = await response.transform(utf8.decoder).join();
  print(stringData);
} finally {
  client.close();
}

Properties

certificate → X509Certificate?
Returns the certificate of the HTTPS server providing the response. Returns null if the connection is not a secure TLS or SSL connection.
read-only
compressionState → HttpClientResponseCompressionState

read-onlyinherited
headers → HttpHeaders
Returns the client response headers.

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>
Discards all data on this stream, but signals when it is done or an error occurred.
inherited
elementAt(int index) → Future<List<int>>
Returns the value of the indexth data event of this stream.
inherited
every(bool test(List<int> element)) → Future<bool>
Checks whether test accepts all elements provided by this stream.
inherited
expand<S>(Iterable<S> convert(List<int> element)) → Stream<S>
Transforms each element of this stream into a sequence of elements.
inherited
firstWhere(bool test(List<int> element), {List<int> orElse()?}) → Future<List<int>>
Finds the first element of this stream matching test.
inherited
fold<S>(S initialValue, S combine(S previous, List<int> element)) → Future<S>
Combines a sequence of values by repeatedly applying combine.
inherited
forEach(void action(List<int> element)) → Future
Executes action on each element of this stream.
inherited
handleError(Function onError, {bool test(dynamic error)?}) → Stream<List<int>>
Creates a wrapper Stream that intercepts some errors from this stream.
inherited
join([String separator = ""]) → Future<String>
Combines the string representation of elements into a single string.
inherited
lastWhere(bool test(List<int> element), {List<int> orElse()?}) → Future<List<int>>
Finds the last element in this stream matching test.
inherited
listen(void onData(List<int> event)?, {Function? onError, void onDone()?, bool? cancelOnError}) → StreamSubscription<List<int>>
Adds a subscription to this stream.
inherited
map<S>(S convert(List<int> event)) → Stream<S>
Transforms each element of this stream into a new stream event.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed.
inherited
pipe(StreamConsumer<List<int>> streamConsumer) → Future
Pipes the events of this stream into streamConsumer.
inherited
redirect([String? method, Uri? url, bool? followLoops]) → Future<HttpClientResponse>
Redirects this connection to a new URL. The default value for method is the method for the current request. The default value for url is the value of the HttpHeaders.locationHeader header of the current response. All body data must have been read from the current response before calling redirect.
reduce(List<int> combine(List<int> previous, List<int> element)) → Future<List<int>>
Combines a sequence of values by repeatedly applying combine.

take(int count) → Stream<List<int>>
Provides at most the first count data events of this stream.
inherited
takeWhile(bool test(List<int> element)) → Stream<List<int>>
Forwards data events while test is successful.
inherited
timeout(Duration timeLimit, {void onTimeout(EventSink<List<int>> sink)?}) → Stream<List<int>>

inherited
where(bool test(List<int> event)) → Stream<List<int>>
Creates a new stream from this stream that discards some elements.
