Flatpak stores data for installed applications (the XDG config/data folders) under $HOME/.var
If you have previously installed Remmina with another package manager, you will have to transfer what was under $HOME/.config/remmina and $HOME/.local/share/remmina under, respectively ~/.var/app/org.remmina.Remmina/config/remmina and ~/.var/app/org.remmina.Remmina/data/remmina
There is an official Arch Linux Remmina package. Or, if you want to use the AUR, install remmina-git.
There are also some external, not supported plugins provided by Muflone and other
Arch Remmina Protocol plugins
