I'm using macOS.

Using https://gtkdcoding.com/2019/02/15/0010-checkbutton.html by Ron Tarrant - I get this warning the first click of the check box:

(test:5169): Gtk-WARNING **: 17:44:07.780: Could not load a pixbuf from /org/gtk/libgtk/theme/Adwaita/assets/check-symbolic.svg.

Still seems to work. I used 'brew install gtk+3' and dub.

Looks like only the fallback theme is installed, the easiest fix would
be to install the Adwaita icon theme.

brew install adwaita-icon-theme
