Use case

At WWDC 2019, Apple announced the general availability of Project Catalyst in macOS 10.15. Project Catalyst - used to be Marzipan - allows for developers to run apps written for iOS natively on macOS through the use of the shared UIKit. This allows for one codebase to compile to iOS (iPadOS) and macOS. This aligns nicely with the first statement on https://flutter.dev

Flutter is Google’s portable UI toolkit for building beautiful, natively-compiled applications for mobile, web, and desktop from a single codebase.

Proposal

• Add support for compiling to macOS using Project Catalyst as a separate target for flutter build
• Add Cupertino styles for UIKit on macOS following the iPad Apps for Mac Human Interface Guidelines
