any method
Checks whether test
accepts any element provided by this stream.
Calls test
on each element of this stream.
If the call returns true
, the returned future is completed with true
and processing stops.
If this stream ends without finding an element that test
accepts,
the returned future is completed with false
.
If this stream emits an error, or if the call to test
throws,
the returned future is completed with that error,
and processing stops.
Example:
final result =
await Stream.periodic(const Duration(seconds: 1), (count) => count)
.take(15)
.any((element) => element >= 5);
print(result); // true
Implementation
@override
Future<bool> any(bool Function(T element) test) => stream.any(test);
