[firebase_dynamic_links] why onLink behaviour is different between iOS and Android?

[dev-mush]

I'm using both uni_links to handle deeplinks and firebase dynamic links to handle dynamic linking for marketing campaigns.

When I open the app with a Dynamic Link on iOS the behaviour is what I would expect, dynamicLink passed by the onSuccess callback of the onLink stream is the actual dynamic link we've used (like myapp.page.link) and dynamicLink?.link contains the actual deeplink (like https://mysite.com/path), however on android the dynamicLink I receive is already my actual deeplink, and the uni_links handler to handle actual deeplinks is invoked as well, here's some code to give more context:

FirebaseDynamicLinks.instance.onLink(
      onSuccess: (PendingDynamicLinkData? dynamicLink) async {
        // on iOS dynamic link is the dynamic link like myapp.page.link, on android is the actual deeplink that the dynamic link points at
        final Uri? deepLink = dynamicLink?.link;   

        if (deepLink != null) {
          _handleDeeplink(deepLink);
        }
      },
      onError: (OnLinkErrorException e) async {
        debugPrint(e.message);
      },
    );

Why is the behaviour different between the two platforms? Am I missing something?
