However, since the view controller is gated behind a private API, we will use [UIReferenceLibraryViewController](https://developer.apple.com/documentation/uikit/uireferencelibraryviewcontroller) instead, which is functionally identical and visually very similar. | Native | UIReferenceLibraryViewController| | ------------- | ------------- | | <img src="https://github.com/flutter/engine/assets/36148254/763004f0-970f-4d8a-9a9a-133401ef0c1b" width="360" />| <img src="https://github.com/flutter/engine/assets/36148254/b20fe03f-6c9d-4a4a-98dc-8bcd840406db" width="360" />| This PR is the engine portion of the changes that will allow this feature change.
