Steps to reproduce

1. Update Flutter to version 3.22.0.
2. Ensure .well-known/apple-app-site-association is correctly configured on the server.
3. Implement autofill hints in your Flutter app.
4. Test the autofill functionality on an iOS device.
5. Try to autofill with some saved credentials

Expected results

Input fields should be automatically populated with relevant data when using autofill on iOS, similar to how it works on Android.

Actual results

Autofill suggestions appear on iOS, but selecting a suggestion does not populate the input fields.

              ),
            ),
