[firebase_dynamic_links] ifl parameter does not take the user to specified url in iOS

[RamithRD]

Hi All,

I'm working on a Flutter app which currently only supports Android.

I've setup Dynamic Links and it's working as intended on Android and other platforms like desktop which I've made it work using the ofl parameter to take users to the same content on our website. I've also added the ifl parameter with the same url specified in the ofl but when I try open the dynamic link on Safari (iOS simulator), it says invalid dynamic link.

When generating the dynamic link, I did not pass the IosParameters since I'm not supporting iOS apps currently and I haven't registered an iOS app in Firebase console as well.

How do I setup my dynamic link to open my website when accessed from an iOS device?

This is the debug view of my dynamic link generated by concatenating both ofl and ifl parameters to the long url:

For anyone landing here after the Aug 2025 shutdown: there's no drop-in. You need a URL that branches on User-Agent (App Store / intent:// with browser_fallback_url / website) and skips redirecting crawlers so previews survive.
