Describe the bug

Firstly, opening paywall on macOS not working from purchases flutter ui, it sends error ios platform is required, why would you add macOS badge to package in that case?

Secondly, PaywallFooterView is throwing error:

"A UIKitView widget is trying to create a PlatformView with an unregistered type: < com.revenuecat.purchasesui/PaywallFooterView >"
"If you are the author of the PlatformView, make sure `registerViewFactory` is invoked.
See: https://docs.flutter.dev/development/platform-integration/platform-views#on-the-platform-side-1 for more details.
If you are not the author of the PlatformView, make sure to call `GeneratedPluginRegistrant.register`." 

I have following 2 line in my GeneratedPluginRegistrant.register:

PurchasesFlutterPlugin.register(with: registry.registrar(forPlugin: "PurchasesFlutterPlugin"))
PurchasesUiFlutterPlugin.register(with: registry.registrar(forPlugin: "PurchasesUiFlutterPlugin"))

Hi @Albertbol

Sorry about this but it looks like we need to do some work on the SDK to support MacOS in purchases_ui_flutter. We don't have an estimate yet on when this will get done. We will be removing the badge from pub.dev until we get that done.

Sorry again about all the trouble.

Just a +1 for this feature—no other paywall builders that I've explored (Superwall, Adapty) currently support Flutter-macOS paywalls—it would be fantastic if RC could fill this gap in the market 🙏🏻
