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.

Implements

Properties

hasTerminal bool
Returns true if there is a terminal attached to stdout.
read-only
nonBlocking IOSink
Get a non-blocking IOSink.
read-only
supportsAnsiEscapes bool
Whether connected to a terminal that supports ANSI escape sequences. [...]
read-only
terminalColumns int
Get the number of columns of the terminal. [...]
read-only
terminalLines int
read-only
done Future
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.
read-only, inherited
encoding Encoding
The Encoding used when writing strings. Depending on the underlying consumer this property might be mutable.
read / write, inherited
hashCode int
The hash code for this object. [...]
read-only, inherited
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited

Methods

add(List<int> data) → void
Adds byte data to the target consumer, ignoring encoding. [...]
inherited
addError(Object error, [ StackTrace stackTrace ]) → void
Passes the error to the target consumer as an error event. [...]
inherited
addStream(Stream<List<int>> stream) Future
Adds all elements of the given stream to this. [...]
inherited
close() Future
Close the target consumer. [...]
inherited
flush() Future
Returns a Future that completes once all buffered data is accepted by the underlying StreamConsumer. [...]
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
toString() String
Returns a string representation of this object.
inherited
write(Object object) → void
Converts obj to a String by invoking Object.toString and adds the encoding of the result to the target consumer. [...]
inherited
writeAll(Iterable objects, [ String sep = "" ]) → void
Iterates over the given objects and writes them in sequence. [...]
inherited
writeCharCode(int charCode) → void
Writes the character of charCode. [...]
inherited
writeln([Object object = "" ]) → void
Converts obj to a String by invoking Object.toString and writes the result to this, followed by a newline. [...]
inherited

Operators

operator ==(dynamic other) bool
The equality operator. [...]
