TLDR:

Illegal qualified name:

https://github.com/fluttercommunity/plus_plugins/blob/13e170479b3c66c890fa401f5fdb3af141faf67a/packages/share_plus/share_plus/windows/share_plus_windows_plugin.h#L61

Followed by a lot of template errors in windows/vector.h

Start with windows/share_plus_windows_plugin.h at line 61 and windows/vector.h, where the MSVC C++20 build reports the first qualified-name and template errors. Reproduce with Windows 10, Flutter 3.47.0, share_plus 12.3.0, and the shown flutter run -v compilation; done means the share_plus Windows plugin builds successfully with the reported configuration.
