whereNotNull method

Returns a new lazy Iterable containing all elements of this collection that are not null.

This method filters the elements of the collection and includes only those elements that are not null in the resulting iterable.

• Returns: A new lazy Iterable containing all elements of this collection that are not null.

• Example:

  Iterable<String?> words = ['apple', null, 'banana', null, 'cherry'];
  Iterable<String> nonNullWords = words.whereNotNull();
  
  print(nonNullWords); // Output: ['apple', 'banana', 'cherry']
  

Note: This method creates a new lazy Iterable and does not modify the original collection. It allows you to filter out null elements from the collection.
