you probably want the variable inside the quotes ;) 

you can install the hello-world snap to check the default environment a
snap gets ...

ubuntu at pi3:~$ hello-world.env |grep SNAP_USER_DATA
SNAP_USER_DATA=/home/ubuntu/snap/hello-world/27

there is also a hellp-world.sh in that package that spawns a shell
inside a typical snap sandbox so you can inspect the environment more
and try out what is writable etc.
