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.

- Implementers
Constructors
- IOSink(StreamConsumer<
List< target, {Encoding encoding = utf8})int> >factory - Create an IOSink that outputs to a
targetStreamConsumer of bytes. [...]
Properties
- done → Future read-only, override
- A future that will complete when the consumer closes, or when an error occurs. [...]
- encoding ↔ Encoding read / write
- The Encoding used when writing strings. [...]
- hashCode → int read-only, inherited
- The hash code for this object. [...]
- runtimeType → Type read-only, inherited
- A representation of the runtime type of the object.
Methods
- add(
List< int> data) → voidoverride - Adds byte
datato the target consumer, ignoring encoding. [...] - addError(
Object error, [StackTrace? stackTrace]) → void override - Passes the error to the target consumer as an error event. [...]
- addStream(
Stream< List< stream) → Futureint> >override - Adds all elements of the given
stream. [...] - close(
) → Future override - Close the target consumer. [...]
- flush(
) → Future - Returns a Future that completes once all buffered data is accepted by the underlying StreamConsumer. [...]
- noSuchMethod(
Invocation invocation) → dynamic inherited - Invoked when a non-existent method or property is accessed. [...]
- toString(
) → String inherited - A string representation of this object. [...]
- write(
Object? object) → void override - Converts
objectto a String by invoking Object.toString and adds the encoding of the result to the target consumer. [...] - writeAll(
Iterable objects, [String separator = ""]) → void override - Iterates over the given
objectsand writes them in sequence. [...] - writeCharCode(
int charCode) → void override - Writes the character of
charCode. [...] - writeln(
[Object? object = ""]) → void override - Converts
objectto a String by invoking Object.toString and writes the result tothis, followed by a newline. [...]
Operators
- operator ==(
Object other) → bool inherited - The equality operator. [...]
