Socket class Null safety

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.

Socket()

Properties

address → InternetAddress: The InternetAddress used to connect this socket. [...]
read-only
done → Future: 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.
read-only, override
encoding ↔ Encoding: The Encoding used when writing strings. Depending on the underlying consumer this property might be mutable.
read / write, inherited
first → Future<Uint8List>: The first element of this stream. [...]
read-only, inherited
hashCode → int: The hash code for this object. [...]
read-only, inherited
isBroadcast → bool: Whether this stream is a broadcast stream.
read-only, inherited
isEmpty → Future<bool>: Whether this stream contains any elements. [...]
read-only, inherited
last → Future<Uint8List>: The last element of this stream. [...]
read-only, inherited
length → Future<int>: The number of elements in this stream. [...]
read-only, inherited
port → int: The port used by this socket. [...]
read-only
remoteAddress → InternetAddress: The remote InternetAddress connected to by this socket. [...]
read-only
remotePort → int: The remote port connected to by this socket. [...]
read-only
runtimeType → Type: A representation of the runtime type of the object.
read-only, inherited
single → Future<Uint8List>: The single element of this stream. [...]

Methods

add(List<int> data) → void: Adds byte data to the target consumer, ignoring encoding. [...]
inherited
addError(Object error, [StackTrace? stackTrace]) → void: Passes the error to the target consumer as an error event. [...]
inherited
addStream(Stream<List<int>> stream) → Future: Adds all elements of the given stream to this. [...]
inherited
any(bool test(Uint8List element)) → Future<bool>: Checks whether test accepts any element provided by this stream. [...]
inherited
asBroadcastStream({void onListen(StreamSubscription<Uint8List> subscription), void onCancel(StreamSubscription<Uint8List> subscription)}) → Stream<Uint8List>: Returns a multi-subscription stream that produces the same events as this. [...]
inherited
asyncExpand<E>(Stream<E>? convert(Uint8List event)) → Stream<E>: Transforms each element into a sequence of asynchronous events. [...]
inherited
asyncMap<E>(FutureOr<E> convert(Uint8List 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
close() → Future: Close the target consumer. [...]
override
contains(Object? needle) → Future<bool>: Returns whether needle occurs in the elements provided by this stream. [...]
inherited
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. [...]
distinct([bool equals(Uint8List previous, Uint8List next)]) → Stream<Uint8List>: 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<Uint8List>: Returns the value of the indexth data event of this stream. [...]
inherited
every(bool test(Uint8List element)) → Future<bool>: Checks whether test accepts all elements provided by this stream. [...]
inherited
expand<S>(Iterable<S> convert(Uint8List element)) → Stream<S>: Transforms each element of this stream into a sequence of elements. [...]
inherited
firstWhere(bool test(Uint8List element), {Uint8List orElse()}) → Future<Uint8List>: Finds the first element of this stream matching test. [...]
inherited
flush() → Future: Returns a Future that completes once all buffered data is accepted by the underlying StreamConsumer. [...]
inherited
fold<S>(S initialValue, S combine(S previous, Uint8List element)) → Future<S>: Combines a sequence of values by repeatedly applying combine. [...]
inherited
forEach(void action(Uint8List element)) → Future: Executes action on each element of this stream. [...]
inherited
getRawOption(RawSocketOption option) → Uint8List: Use getRawOption to get low level information about the RawSocket. See RawSocketOption for available options. [...]
handleError(Function onError, {bool test(dynamic error)}) → Stream<Uint8List>: 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
listen(void onData(Uint8List event), {Function? onError, void onDone(), bool? cancelOnError}) → StreamSubscription<Uint8List>: Adds a subscription to this stream. [...]
inherited
map<S>(S convert(Uint8List 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<Uint8List> streamConsumer) → Future: Pipes the events of this stream into streamConsumer. [...]
inherited
reduce(Uint8List combine(Uint8List previous, Uint8List element)) → Future<Uint8List>: Combines a sequence of values by repeatedly applying combine. [...]
inherited
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. [...]
singleWhere(bool test(Uint8List element), {Uint8List orElse()}) → Future<Uint8List>: Finds the single element in this stream matching test. [...]
inherited
skip(int count) → Stream<Uint8List>: Skips the first count data events from this stream. [...]
inherited
skipWhile(bool test(Uint8List element)) → Stream<Uint8List>: Skip data events from this stream while they are matched by test. [...]
inherited
take(int count) → Stream<Uint8List>: Provides at most the first count data events of this stream. [...]
inherited
takeWhile(bool test(Uint8List element)) → Stream<Uint8List>: Forwards data events while test is successful. [...]
inherited
timeout(Duration timeLimit, {void onTimeout(EventSink<Uint8List> sink)}) → Stream<Uint8List>: Creates a new stream with the same events as this stream. [...]

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.
