Absence of Linus and windows folders

Due to the cross platform functionality offered by flutter and the ability to run flutter projects on different platforms, it's very essential to include both the Linus and windows folders to make it easy for flutter developers to run and test their mobile applications using any of the diverse options available.

Start at the Flutter project root and inspect the existing platform support and project configuration. Determine the required Linux and Windows folders for this application, then verify that the project can run and be tested on both platforms; completion means both folders are included and the platform builds work.
