WhereNotNullStreamTransformer<T extends Object> class Null safety

Create a Stream which emits all the non-null elements of the Stream, in their original emission order.

Example

Stream.fromIterable(<int?>[1, 2, 3, null, 4, null])
  .transform(WhereNotNullStreamTransformer())
  .listen(print); // prints 1, 2, 3, 4

// equivalent to:

Stream.fromIterable(<int?>[1, 2, 3, null, 4, null])
  .transform(WhereTypeStreamTransformer<int?, int>())
  .listen(print); // prints 1, 2, 3, 4
