Stdin class Null safety

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>
Checks whether test accepts any element provided by this stream.
inherited
asBroadcastStream({void onListen(StreamSubscription<List<int>> subscription)?, void onCancel(StreamSubscription<List<int>> subscription)?}) → Stream<List<int>>
Returns a multi-subscription stream that produces the same events as this.
inherited
asyncExpand<E>(Stream<E>? convert(List<int> event)) → Stream<E>
Transforms each element into a sequence of asynchronous events.
inherited
asyncMap<E>(FutureOr<E> convert(List<int> event)) → Stream<E>
Creates a new stream with each data event of this stream asynchronously mapped to a new event.
inherited
cast<R>() → Stream<R>
Adapt this stream to be a Stream<R>.
inherited
contains(Object? needle) → Future<bool>
Returns whether needle occurs in the elements provided by this stream.
inherited
distinct([bool equals(List<int> previous, List<int> next)?]) → Stream<List<int>>
Skips data events if they are equal to the previous data event.
inherited
drain<E>([E? futureValue]) → Future<E>
