Background

You can build a Flutter Windows app in Visual Studio once you've built the app once (using flutter build windows or flutter run -d windows). This requires doing a full build of the application, which can take a long time for complex projects.

On iOS, you can run flutter build ios --config-only to generate the necessary build files for the Flutter project to be buildable in Xcode.

Solution

Add a flutter build windows --config-only. This should generate all the files necessary to build a Flutter Windows app in Visual Studio, without actually building the Flutter Windows app.
