Issue:
"Issue with pana Tool Using Outdated Flutter SDK on pub.dev"
I recently uploaded the `antinna_ui_kit` package to [pub.dev](https://pub.dev/packages/antinna_ui_kit), which requires the Dart SDK version `>=3.4.4 <4.0.0`. However, during the analysis, it seems that `pana` is currently using Flutter version 3.22.2, Even though flutter new Stable version is there.
