[firebase_dynamic_links] Add the ofl parameter for links created in app

[Young-Slim-Jim]

In the App my team and me create we use dynamic links that lead our users to certain parts of the app. These links are created with the firebase_dynmic_links package in another part of the app. Everything is working fine, which is great. However, when the link, which was created in the app, is opened on a Desktop, the page is empty. Looking into the documentation it's easy to find out that one must set the ofl parameter to the url of the website that should be opened in this case. But its currently not possible to set such a parameter with the flutter package. I also tried adding the ofl parater to the base uri from which the dynamic is build, but that also did not work. Writing this using Flutter 2.2.0 and firebase_dynamic_links 2.0.4
Thank you.
