IOSink class Null safety

A combined byte and text output.

An IOSink combines a StreamSink of bytes with a StringSink, and allows easy output of both bytes and text.

Writing text (write) and adding bytes (add) may be interleaved freely.

While a stream is being added using addStream, any further attempts to add or write to the IOSink will fail until the addStream completes.

It is an error to add data to the IOSink after the sink is closed.

Implementers

Constructors

IOSink(StreamConsumer<List<int>> target, {Encoding encoding: utf8}): Create an IOSink that outputs to a target StreamConsumer of bytes. [...]
factory

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
hashCode → int: The hash code for this object. [...]
read-only, inherited
runtimeType → Type: A representation of the runtime type of the object.
read-only, inherited

add(List<int> data) → void: Adds byte data to the target consumer, ignoring encoding. [...]
override
addError(Object error, [StackTrace? stackTrace]) → void: Passes the error to the target consumer as an error event. [...]
override
addStream(Stream<List<int>> stream) → Future: Adds all elements of the given stream to this. [...]
override
close() → Future: Close the target consumer. [...]
override
flush() → Future: Returns a Future that completes once all buffered data is accepted by the underlying StreamConsumer. [...]
noSuchMethod(Invocation invocation) → dynamic: Invoked when a non-existent method or property is accessed. [...]
inherited
toString() → String: Returns a string representation of this object.
inherited
write(Object? obj) → void: Converts obj to a String by invoking Object.toString and adds the encoding of the result to the target consumer. [...]
override
writeAll(Iterable objects, [String separator = ""]) → void: Iterates over the given objects and writes them in sequence. [...]
override
writeCharCode(int charCode) → void: Writes the character of charCode. [...]
override
writeln([Object? obj = ""]) → void: Converts obj to a String by invoking Object.toString and writes the result to this, followed by a newline. [...]
