[linux] Wrong accent color on Manjaro GNOME

I tried to build and run a flutter project using _system_theme_ on the latest version of Linux Manjaro GNOME. (`GNOME 48` | `Linux 6.14.6-2-MANJARO`)
In the OS appearance settings UI, I've set the accent color to _orange_. _System_theme_ gets an accent color from the OS but it seems to get the wrong one: the default bluish green (`Color(alpha: 1.0000, red: 0.0863, green: 0.6275, blue: 0.5216, colorSpace: ColorSpace.sRGB)`)

When I run the following command, it returns `'orange'`:
`gsettings get org.gnome.desktop.interface accent-color`

**This problem seems to stem more from the OS. The Settings UI also uses the bluish green accent color (see the green outline in "_Style_" setting).**


But as the command above returns the color selected by the user, maybe _system_theme_ can find a workaround or simply wait the OS to expose the accent color in a better way, you see.

Thanks for considering this feedback.
