install from repo via flakes

[brothermechanic]

Hello
Help me, please, as new user, how to install packages via flakes
(via channels works, but i need flakes instead)
i get this error

$ nix profile install github:lopsided98/nix-ros-overlay#gazebo
error: flake 'github:lopsided98/nix-ros-overlay' does not provide attribute 'packages.x86_64-linux.gazebo', 'legacyPackages.x86_64-linux.gazebo' or 'gazebo'

Hello.
I think that you need to specify which ros distribution you want to use.

As an example, I use

nix shell -L github:lopsided98/nix-ros-overlay#humble.gazebo --command gazebo

to run gazebo from the humble distribution.

Cool!
It works! Tank you!

I need to fix this for real though, it just happens to work in this case since gazebo is part of the top-level package set and the distro specific package set. With other packages like colcon, there isn't a work-around, see: #150
