As with Pixar, Disney has confirmed that all Star Wars movies will be available on day one of Disney+, with the exception of these two films, and the forthcoming, Star Wars; The Rise of Skywalker.
Only three Star Wars films have ever been available on Netflix and two of them still are.
The deal between Disney and Netflix was signed after the release of Star Wars: The Force Awakens so it never appeared.
Rogue One: A Star Wars Story appeared in July of 2017 and left Netflix this past January.
