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.
An IOSink is intended for writing bytes.
Strings written through write or writeCharCode will be converted
to bytes using encoding.
Integer data added using add or addStream will be treated as byte data,
and will be truncated to unsigned 8-bit values as by using int.toUnsigned.
No guarantees are given for when such a conversion happens, since it
depends on the implementation behind the sink.
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.

Properties
- done → Future
-
A future that will complete when the consumer closes, or when an
error occurs.

Methods
-
add(
List< int> data) → void -
Adds byte
datato 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< stream) → Futureint> > -
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
objectto 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
objectsand writes them in sequence.override -
writeCharCode(
int charCode) → void -
Writes the character of
charCode.override -
writeln(
[Object? object = ""]) → void -
Converts
objectto a String by invoking Object.toString and writes the result tothis, followed by a newline.override
Operators
-
operator ==(
Object other) → bool -
The equality operator.
