Stdin class
The standard input stream of the process.
Allows both synchronous and asynchronous reads from the standard input stream.
Mixing synchronous and asynchronous reads is undefined.

Methods
- any(bool test(List<int> element)) → Future<bool>
inherited
- Checks whether
test accepts any element provided by this stream. - asBroadcastStream({void onListen(StreamSubscription<List<int>> subscription)?, void onCancel(StreamSubscription<List<int>> subscription)?}) → Stream<List<int>>
inherited
- Returns a multi-subscription stream that produces the same events as this.
- asyncExpand<E>(Stream<E>? convert(List<int> event)) → Stream<E>
inherited
- Transforms each element into a sequence of asynchronous events.
- asyncMap<E>(FutureOr<E> convert(List<int> event)) → Stream<E>
inherited
- Creates a new stream with each data event of this stream asynchronously mapped to a new event.
- cast<R>() → Stream<R>
inherited
- Adapt this stream to be a
Stream<R>. - contains(Object? needle) → Future<bool>
inherited
- Returns whether
needle occurs in the elements provided by this stream. - distinct([bool equals(List<int> previous, List<int> next)?]) → Stream<List<int>>
inherited
- Skips data events if they are equal to the previous data event.
- drain<E>([E? futureValue]) → Future<E>
inherited
- Discards all data on this stream, but signals when it is done or an error occurred.
- elementAt(int index) → Future<List<int>>
inherited
- Returns the value of the
indexth data event of this stream. - every(bool test(List<int> element)) → Future<bool>
inherited
- Checks whether
test accepts all elements provided by this stream. - expand<S>(Iterable<S> convert(List<int> element)) → Stream<S>
inherited
- Transforms each element of this stream into a sequence of elements.
- firstWhere(bool test(List<int> element), {List<int> orElse()?}) → Future<List<int>>
inherited
- Finds the first element of this stream matching
test. - fold<S>(S initialValue, S combine(S previous, List<int> element)) → Future<S>
inherited
- Combines a sequence of values by repeatedly applying
combine. - forEach(void action(List<int> element)) → Future
inherited
- Executes
action on each element of this stream. - handleError(Function onError, {bool test(dynamic error)?}) → Stream<List<int>>
inherited
- Creates a wrapper Stream that intercepts some errors from this stream.
- join([String separator = ""]) → Future<String>
inherited
- Combines the string representation of elements into a single string.
- lastWhere(bool test(List<int> element), {List<int> orElse()?}) → Future<List<int>>
inherited
- Finds the last element in this stream matching
test. - listen(void onData(List<int> event)?, {Function? onError, void onDone()?, bool? cancelOnError}) → StreamSubscription<List<int>>
inherited
- Adds a subscription to this stream.
- map<S>(S convert(List<int> event)) → Stream<S>
inherited
- Transforms each element of this stream into a new stream event.
- noSuchMethod(Invocation invocation) → dynamic
inherited
- Invoked when a non-existent method or property is accessed.
- pipe(StreamConsumer<List<int>> streamConsumer) → Future
inherited
- Pipes the events of this stream into
streamConsumer. - readByteSync() → int
- Synchronously reads a byte from stdin.
- readLineSync({Encoding encoding = systemEncoding, bool retainNewlines = false}) → String?
- Reads a line from stdin.
- reduce(List<int> combine(List<int> previous, List<int> element)) → Future<List<int>>
inherited
- Combines a sequence of values by repeatedly applying
combine. - singleWhere(bool test(List<int> element), {List<int> orElse()?}) → Future<List<int>>
inherited
- Finds the single element in this stream matching
test. - skip(int count) → Stream<List<int>>
inherited
- Skips the first
count data events from this stream. - skipWhile(bool test(List<int> element)) → Stream<List<int>>
inherited
- Skip data events from this stream while they are matched by
test. - take(int count) → Stream<List<int>>
inherited
- Provides at most the first
count data events of this stream. - takeWhile(bool test(List<int> element)) → Stream<List<int>>
inherited
- Forwards data events while
test is successful. - timeout(Duration timeLimit, {void onTimeout(EventSink<List<int>> sink)?}) → Stream<List<int>>
