Package gobject-introspection-1.0 was not found in the pkg-config search path

I am running current Gnome on Arch Linux. I have gtk4 library installed.

go run -v ./gtk4/simple
github.com/diamondburned/gotk4/pkg/core/gerror
# pkg-config --cflags  -- glib-2.0 gobject-introspection-1.0
Package gobject-introspection-1.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gobject-introspection-1.0.pc'
to the PKG_CONFIG_PATH environment variable
Package 'gobject-introspection-1.0', required by 'virtual:world', not found

I am not familiar with GTK development, so I might be missing something obvious.

The issue was resolved with

sudo pacman -S gobject-introspection
