demo app doesn't build

[BigAppsAndroid1]

try to build demo app "as is" in emulator iPhone 14 Pro Max without success.

Failed to build iOS app
Error (Xcode): ../../../.pub-cache/hosted/pub.dev/preload_page_view-0.1.6/lib/preload_page_view.dart:179:15: Error: The method 'PageMetrics.copyWith' doesn't have the named parameter 'devicePixelRatio' of overridden method 'Object with ScrollMetrics.copyWith'.

Hi @BigAppsAndroid1, That's surprising; I just tried again, and it works (screenshot attached). Can you please check that you're on the "main" branch?

EDIT: Maybe that's related to your Flutter version. I'm currently on 3.7.12.

I can confirm that the problem occours when upgrading from 3.7.12 to 3.10.
The devicePixelRatio parameter is now required.
Maybe some of the libraries used need to be updated.
A quick fix is to downgrade to 3.7.12. go to the directory wehe flutter is installed and run "git checkout 3.7.12".

Hi @Damianoux, Yes, absolutely. I have started migrating to Flutter 3.10, which implies migrating to Dart 3. Since many parts of Iridium depend on dfunc, we must migrate the use of Product (--> D3 records), Coproduct (--> D3 sealed classes), and Either (--> D3 sealed classes + pattern matching). Work in progress.
See ookami-kb/dfunc#25 and https://github.com/ookami-kb/dfunc/pull/25/commits

Dart 3 Migration complete.
