firstWhereOrNull(bool test(V)) → V?
Return first element that's pass in test or null if not found.
flat() → List<V>
Flatting a list that has other lists inside other lists inside other lists ... recursive
forEachAsync(Future<void> forEach(V element), [int parallels = 1]) → Future<void>
Iterable elements with support async function and runs it's in parallels
