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.

Constructors
- IOSink(StreamConsumer<List<int>> target, { Encoding encoding: utf8 })
factory
- Create an IOSink that outputs to a
target StreamConsumer of bytes. [...]
Properties
- done → Future
read-only, override
- 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.
- encoding ↔ Encoding
read / write
- The Encoding used when writing strings. Depending on the underlying consumer this property might be mutable.
- 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) → void
override
- Adds byte
data to 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<int>> stream) → Future
override
- Adds all elements of the given
stream to this. [...] - close() → Future
override
- Close the target consumer. [...]
- flush() → Future
- Returns a Future that completes once all buffered data is accepted by the underlying StreamConsumer. [...]
- write(Object obj) → void
override
- Converts
obj to 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
objects and writes them in sequence. [...] - writeCharCode(int charCode) → void
override
- Writes the character of
charCode. [...] - writeln([Object obj = "" ]) → void
override
- Converts
obj to a String by invoking Object.toString and writes the result to this, followed by a newline. [...] - noSuchMethod(Invocation invocation) → dynamic
inherited
- Invoked when a non-existent method or property is accessed. [...]
- toString() → String
inherited
- Returns a string representation of this object.
Operators
- operator ==(dynamic other) → bool
inherited
- The equality operator. [...]
