At some point I have to reset my application window's root view controller. After that, launch(url); from dart it is printing warning Warning: Attempt to present <SFSafariViewController: 0x7fc42e866c00> on <FlutterViewController: 0x7fc42e828e00> whose view is not in the window hierarchy! in the log.

Steps to reproduce.

1. At any point reset windows root view controller.
2. Call from dart after that.

From flutter/plugins repo, I could see that the url_launcher plugin native side is keeping rootviewcontroller while initialising the plugin
