GoLand

GoLand is a cross-platform IDE built specially for Go developers

GoLand is available for a free 30-day evaluation. Monthly and yearly subscription options are available for companies and individual users.

If you want to use the Go installation of your system, flatpak mounts your root directory into /var/run/host . You can set your GOROOT accordingly (e.g. /var/run/host/usr/lib/go).
