  ## Flutter and dart recommendations:
  # 
  #  Recommended in 2026-09:
  #  Use aur/flutter-bin (https://aur.archlinux.org/packages/flutter-bin) or chaotic-aur/flutter-bin (https://aur.chaotic.cx/ | https://aur.chaotic.cx/stats/search?search=flutter-bin | https://builds.garudalinux.org/repos/chaotic-aur/x86_64/#:~:text=flutter-bin).
  # 
  #  Recommended in beginning of 2026:
  #  Use 'arch4edu' repository (https://wiki.archlinux.org/title/Unofficial_user_repositories#arch4edu).
  #  This later errored out with "Wrong full snapshot version, expected '0451907c2eaa8467e848c0067bfe8ed4' found '78da37fed6bf1489361a312568249f3f'" or so.
