flutter create --platforms=windows,macos,linux .

Is the one command that you need to run in terminal of your root project directory. You can specify platforms in the comma seperated list.

Like mentioned in the doc https://docs.flutter.dev/development/platform-integration/desktop#add-desktop-support-to-an-existing-flutter-app

List of platforms:https://docs.flutter.dev/development/platform-integration/desktop#add-desktop-support-to-an-existing-flutter-app

To enable disable platforms let say we want to disable ios altogether you can use and create a project later. Now you wont have ios as it is not available.

Well you can toggle the config and simply run the above mentioned command to go for ios

flutter config --no-enable-ios

You can follow this link for the config commands. https://docs.flutter.dev/development/platform-integration/desktop#set-up

So lets say you have a case where you need to add only windows and mac you can disable other platforms and use the create command.

Now for the existing project if you want to enable or add a platform you can use the above create with platforms flag

NOTE: CONFIG SETTINGS ARE USUALLY GLOBAL There are many ways we can counter it. we can make use isolated development too complicated for simple usecase.

We can use FVM https://fvm.app/ for the configs so that it doesnot affect our core sdk.
