Welcome ! In the best case scenario, it'd be best to do it all at once! Yikes! really, take up your cabinets- redo the floor wall to wall & then replace with new canbinets.
But not everybody can do that. But your new floor needs to be under the Dishwasher, stove & ref. And an island if you have one. If you can't do that, I guess I'd do the cabinets first also, but think about your flooring as you are doing it.
