CMake Error at CMakeLists.txt (project) - could not find any instance of Visual Studio

Question

if you're getting an issue like this:

$ flutter build windows
CMake Error at CMakeLists.txt:3 (project):
 Generator
 Visual Studio 16 2019
 could not find any instance of Visual Studio.
Unable to generate build file

It's because flutter doesn't support visual studio 2026 yet: https://github.com/flutter/flutter/blob/f35a2875aecafd728932621ae41a1ac4099e16a6/packages/flutter_tools/lib/src/windows/visual_studio.dart#L184-L187

So, meanwhile flutter updates their sdk, revert to the older visual studio 2022 version
