Conformance of 'AppSettingsPlugin' to protocol 'FlutterPlugin' crosses into main actor-isolated

[vscmaster]

Hi folks,

Could you please take a look on the issue below.

ConformanceIsolation (Xcode): Conformance of 'AppSettingsPlugin' to protocol 'FlutterPlugin' crosses into main actor-isolated code and can cause data races /Users/vi/.pub-cache/hosted/pub.dev/app_settings-6.1.1/ios/app_settings/Sources/app_settings/AppSettingsPlugin.swift:5:42

What I did to fix it is to add @preconcurrency for the FlutterPlugin and it compiles.

like this:
@MainActor public class AppSettingsPlugin: NSObject, @preconcurrency FlutterPlugin, UIWindowSceneDelegate { .... }

flutter doctor

I found out that this code is added in the repo, but when I try to increase version to 6.1.2, version solving fails. Also on pubspec version of this package is 6.1.1. Can I ask when do you want to do 6.1.2 release so we don't have to add @preconcurrency attribute there ? 🙏
