HttpClientResponse class - dart:io library

HTTP response for a client connection.

The body of an 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();
}

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<void>
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>>

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 nonexistent method or property is accessed.

inherited

pipe(StreamConsumer<List<int>> streamConsumer) Future

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.

Forwards data events while test is successful.

inherited

timeout(Duration timeLimit, {void onTimeout(EventSink<List<int>> sink)?}) Stream<List<int>>

inherited

Operators

operator ==(Object other) bool
The equality operator.
