Question

I’m integrating Universal Links in my Flutter project.

In Xcode > Associated Domains, I’ve added:

applinks:abcdefg.info
applinks:*.abcdefg.info

If I add as below, then it is redirecting to the app.

applinks:qwerty.abcdefg.info
applinks:poiuy.abcdefg.info
applinks:cvbnm.abcdefg.info

My links use dynamic subdomains, for example:

https://qwerty.abcdefg.info/
https://poiuy.abcdefg.info/
https://cvbnm.abcdefg.info/

I’ve uploaded a valid apple-app-site-association (AASA) file to each subdomain:

https://qwerty.abcdefg.info/.well-known/apple-app-site-association
https://poiuy.abcdefg.info/.well-known/apple-app-site-association
https://cvbnm.abcdefg.info/.well-known/apple-app-site-association

The app is installed on my iPhone, but when I tap one of these links, it opens in Safari instead of redirecting to my app.

What I’ve Tried

• Added both the root domain and *.abcdefg.info in Associated Domains.
• Verified AASA files are accessible and served with application/json MIME type.
• Installed the app fresh and clicked the links.

Any suggestions would be appreciated.
