Hook into env checkout events for plugins?

I am given certain events that I can hook into for plugin development e.g. `postPush`, `postInit` etc. These work as expected but is there any way I can hook into the event of checking out a different env?

I currently listen to `postPush` then I update a `.env` file which my front end uses to get a cloudfront url. Is there a way I can hook into the checking out of a different env so I can clear out this env variable from the `.env` file as it no longer applicable to the new env.

I would have assumed `postInit` would be triggered in this case but doesn't seem to be.

Thanks!
