IOSink class

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.

Methods

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.
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 nonexistent method or property is accessed.
inherited
toString() String
A string representation of this object.
inherited
write(Object? object) → void
Converts object 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? object = ""]) → void
Converts object to a String by invoking Object.toString and writes the result to this, followed by a newline.
override

Operators

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