dart:io
Stdout class
Stdout represents the IOSink for either stdout or stderr.
It provides a blocking IOSink, so using this to write will block until the output is written.
In some situations this blocking behavior is undesirable as it does not provide the same non-blocking behavior as dart:io in general exposes. Use the property nonBlocking to get an IOSink which has the non-blocking behavior.
This class can also be used to check whether stdout or stderr is connected to a terminal and query some terminal properties.

Properties
- hasTerminal → bool
read-only
- Returns true if there is a terminal attached to stdout.
- nonBlocking → IOSink
read-only
- Get a non-blocking
IOSink. - supportsAnsiEscapes → bool
read-only
- Whether connected to a terminal that supports ANSI escape sequences. [...]
- terminalColumns → int
read-only
- Get the number of columns of the terminal. [...]
- terminalLines → int
read-only
- done → Future
read-only, inherited
- 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, inherited
- 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
inherited
- Adds byte
data to the target consumer, ignoring encoding. [...] - addError(Object error, [ StackTrace stackTrace ]) → void
inherited
- Passes the error to the target consumer as an error event. [...]
- addStream(Stream<List<int>> stream) → Future
inherited
- Adds all elements of the given
stream to this. [...] - close() → Future
inherited
- Close the target consumer. [...]
- flush() → Future
inherited
- 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
- Returns a string representation of this object.
- write(Object object) → void
inherited
- Converts
obj to a String by invoking Object.toString and adds the encoding of the result to the target consumer. [...] - writeAll(Iterable objects, [ String sep = "" ]) → void
inherited
- Iterates over the given
objects and writes them in sequence. [...] - writeCharCode(int charCode) → void
inherited
- Writes the character of
charCode. [...] - writeln([Object object = "" ]) → void
inherited
- Converts
obj to a String by invoking Object.toString and writes the result to this, followed by a newline. [...]
Operators
- operator ==(dynamic other) → bool
inherited
- The equality operator. [...]
