Targeting multiplatform.

[yjchun]

At your website, it says:

If at this point you are wondering how to manage targeting multiple platforms while using the appropriate widget libraries (such as material for mobile, fluent_ui for Windows, and macos_ui for macOS), all of which expect their own root application widget, don't fret - this can be done relatively easily and there is a special codelab for this coming soon!

If this codelab is not done yet,
can you outline your idea about this? I only could think of wrapping all the widgets. (eg: flutter_platform_widgets)
