No, right now, they are only implemented in snapd.
You need to place the correct file in the meta/hooks/ folder (if you are
using snapcraft, do this in the prime/ directory, before "snapcraft snap
prime/").

There is an example available at
https://github.com/snapcore/snapd/tree/master/tests/lib/snaps/basic-hooks/meta/hooks.

Hope that helps!
