Hi everyone, I’ve been stuck on an issue with iOS Universal Links for about a week and could really use some help.
The problem When tapping a Universal Link on iOS, my Flutter app opens correctly (desired behavior) — but immediately afterward, Safari opens the same link in the browser. So both the app and the browser open. This only happens on iOS. On Android everything works as expected.
What works If the link is simply the domain, like: https://mydomain.com
…then the app opens without triggering the browser afterward. This is the correct behavior.
What doesn’t work If the link includes a path or parameters, like: https://mydomain.com/path https://mydomain.com/path?param=value
…then the app opens, and then the browser opens immediately after.
What I’ve tried
Verified my AASA file using Branch’s validator: https://branch.io/resources/aasa-validator/
→ The AASA file is valid.
Universal Links do open the correct screen inside the app — the issue is the unwanted second step (Safari opening).
Behavior is consistent across different iOS devices.
Extra details
Using Flutter.
Universal Links set up with the standard configuration (associatedDomains, AASA hosted at /.well-known/apple-app-site-association, etc.).
Question Has anyone encountered this issue where Universal Links with paths/params open the app and then open Safari? What could cause iOS to trigger the browser fallback even when the AASA file is valid and the app handles the link correctly?
Any insights, debugging tips, or known edge cases would be incredibly appreciated!
