Socket class

A high-level class for communicating over a TCP socket.

The Socket exposes both a Stream and a IOSink interface, making it ideal for using together with other Streams.

Properties

addressInternetAddress
read-only
Returns the InternetAddress used to connect this socket.
doneFuture
read-only, override
Get a future that will complete when the consumer closes, or when an error occurs. This future is identical to the future returned by close.
portint
read-only
Returns the port used by this socket.
remoteAddressInternetAddress
read-only
Returns the remote InternetAddress connected to by this socket.
remotePortint
read-only
Returns the remote port connected to by this socket.
encodingEncoding
read / write, inherited
The Encoding used when writing strings. Depending on the underlying consumer this property might be mutable.
firstFuture<Uint8List>
read-only, inherited
The first element of this stream. [...]
hashCodeint
read-only, inherited
The hash code for this object. [...]
isBroadcastbool
read-only, inherited
Whether this stream is a broadcast stream.
isEmptyFuture<bool>
read-only, inherited
Whether this stream contains any elements. [...]
lastFuture<Uint8List>
read-only, inherited
The last element of this stream. [...]
lengthFuture<int>
read-only, inherited
The number of elements in this stream. [...]
runtimeTypeType
read-only, inherited
A representation of the runtime type of the object.
singleFuture<Uint8List>
read-only, inherited
The single element of this stream. [...]

Methods

close() → Future
override
Close the target consumer. [...]
destroy() → void
Destroy the socket in both directions. Calling destroy will make the send a close event on the stream and will no longer react on data being piped to it. [...]
getRawOption(RawSocketOption option) → Uint8List
Use getRawOption to get low level information about the RawSocket. See RawSocketOption for available options. [...]
setOption(SocketOption option, bool enabled) → bool
Use setOption to customize the RawSocket. See SocketOption for available options. [...]
setRawOption(RawSocketOption option) → void
Use setRawOption to customize the RawSocket. See RawSocketOption for available options. [...]
add(List<int> data) → void
inherited
Adds byte data to the target consumer, ignoring encoding. [...]
addError(Object error, [ StackTrace stackTrace ]) → void
inherited
Passes the error to the target consumer as an error event. [...]
addStream(Stream<List<int>> stream) → Future
inherited
Adds all elements of the given stream to this. [...]
any(bool test(T element)) → Future<bool>
inherited
Checks whether test accepts any element provided by this stream. [...]
asBroadcastStream({void onListen(StreamSubscription<T> subscription), void onCancel(StreamSubscription<T> subscription) }) → Stream<Uint8List>
inherited
Returns a multi-subscription stream that produces the same events as this. [...]
asyncExpand<E>(Stream<E> convert(T event)) → Stream<E>
inherited
Transforms each element into a sequence of asynchronous events. [...]
asyncMap<E>(FutureOr<E> convert(T event)) → Stream<E>
inherited
Creates a new stream with each data event of this stream asynchronously mapped to a new event. [...]
cast<R>() → Stream<R>
inherited
Adapt this stream to be a Stream<R>. [...]
contains(Object needle) → Future<bool>
inherited
Returns whether needle occurs in the elements provided by this stream. [...]
distinct([bool equals(T previous, T next) ]) → Stream<Uint8List>
inherited
Skips data events if they are equal to the previous data event. [...]
drain<E>([E futureValue ]) → Future<E>
inherited
Discards all data on this stream, but signals when it is done or an error occurred. [...]
elementAt(int index) → Future<Uint8List>
inherited
Returns the value of the indexth data event of this stream. [...]
every(bool test(T element)) → Future<bool>
inherited
Checks whether test accepts all elements provided by this stream. [...]
expand<S>(Iterable<S> convert(T element)) → Stream<S>
inherited
Transforms each element of this stream into a sequence of elements. [...]
firstWhere(bool test(T element), { Uint8List orElse() }) → Future<Uint8List>
inherited
Finds the first element of this stream matching test. [...]
flush() → Future
inherited
Returns a Future that completes once all buffered data is accepted by the underlying StreamConsumer. [...]
fold<S>(S initialValue, S combine(S previous, T element)) → Future<S>
inherited
Combines a sequence of values by repeatedly applying combine. [...]
forEach(void action(T element)) → Future
inherited
Executes action on each element of this stream. [...]
handleError(Function onError, { bool test(dynamic error) }) → Stream<Uint8List>
inherited
Creates a wrapper Stream that intercepts some errors from this stream. [...]
join([String separator = "" ]) → Future<String>
inherited
Combines the string representation of elements into a single string. [...]
lastWhere(bool test(T element), { Uint8List orElse() }) → Future<Uint8List>
inherited
Finds the last element in this stream matching test. [...]
listen(void onData(T event), { Function onError, void onDone(), bool cancelOnError }) → StreamSubscription<Uint8List>
inherited
Adds a subscription to this stream. [...]
map<S>(S convert(T event)) → Stream<S>
inherited
Transforms each element of this stream into a new stream event. [...]
noSuchMethod(Invocation invocation) → dynamic
inherited
Invoked when a non-existent method or property is accessed. [...]
pipe(StreamConsumer<Uint8List> streamConsumer) → Future
inherited
Pipes the events of this stream into streamConsumer. [...]
reduce(Uint8List combine(T previous, T element)) → Future<Uint8List>
inherited
Combines a sequence of values by repeatedly applying combine. [...]
singleWhere(bool test(T element), { Uint8List orElse() }) → Future<Uint8List>
inherited
Finds the single element in this stream matching test. [...]
skip(int count) → Stream<Uint8List>
inherited
Skips the first count data events from this stream. [...]
skipWhile(bool test(T element)) → Stream<Uint8List>
inherited
Skip data events from this stream while they are matched by test. [...]
take(int count) → Stream<Uint8List>
inherited
Provides at most the first count data events of this stream. [...]
takeWhile(bool test(T element)) → Stream<Uint8List>
inherited
Forwards data events while test is successful. [...]
timeout(Duration timeLimit, { void onTimeout(EventSink<T> sink) }) → Stream<Uint8List>
inherited
Creates a new stream with the same events as this stream. [...]
toList() → Future<List<Uint8List>>
inherited
Collects all elements of this stream in a List. [...]
toSet() → Future<Set<Uint8List>>
inherited
Collects the data of this stream in a Set. [...]
toString() → String
inherited
Returns a string representation of this object.
transform<S>(StreamTransformer<Uint8List, S> streamTransformer) → Stream<S>
inherited
Applies streamTransformer to this stream. [...]
where(bool test(T event)) → Stream<Uint8List>
inherited
Creates a new stream from this stream that discards some elements. [...]
write(Object obj) → void
inherited
Converts obj to a String by invoking Object.toString and adds the encoding of the result to the target consumer. [...]
writeAll(Iterable objects, [ String separator = "" ]) → void
inherited
Iterates over the given objects and writes them in sequence. [...]
writeCharCode(int charCode) → void
inherited
Writes the character of charCode. [...]
writeln([Object obj = "" ]) → void
inherited
Converts obj to a String by invoking Object.toString and writes the result to this, followed by a newline. [...]

Operators

operator ==(dynamic other) → bool
inherited
The equality operator. [...]

Static Methods

connect(dynamic host, int port, { dynamic sourceAddress, Duration timeout }) → Future<Socket>
Creates a new socket connection to the host and port and returns a Future that will complete with either a Socket once connected or an error if the host-lookup or connection failed. [...]
startConnect(dynamic host, int port, { dynamic sourceAddress }) → Future<ConnectionTask<Socket>>
Like connect, but returns a Future that completes with a ConnectionTask that can be cancelled if the Socket is no longer needed.
