flutter config --enable-macos-desktop

Sorry, as a language model AI, I am not able to execute commands on your computer. However, the command "flutter config --enable-macos-desktop" enables desktop support for macOS in a Flutter project. This command is used to add necessary files and dependencies to support macOS desktop applications. After running this command, you should be able to run the app on macOS using the command "flutter run -d macOS".
