isEmpty property

  1. @override
Future<bool> get isEmpty
inherited

Whether this stream contains any elements.

Waits for the first element of this stream, then completes the returned future with false. If this stream ends without emitting any elements, the returned future is completed with true.

If the first event is an error, the returned future is completed with that error.

This operation listens to this stream, and a non-broadcast stream cannot be reused after checking whether it is empty.

Implementation

@override
Future<bool> get isEmpty => stream.isEmpty;
