“Nothing” doesn’t exist. Instead, there is “quantum foam” (bigthink.com)

So I wonder, even if it's only appearing very briefly it's still going to exert some small gravitational effect. And who is to say the density of quantum foam is perfectly evenly distributed through the universe, within, through and between galaxies? Could this be an alternative explanation to dark matter?

I don't think so. Remember: This is energy being converted to mass, not mass coming out of nowhere.

Ah right. So, an alternative to dark energy and dark mass?

No no that's a completely different phenomenon. This is the phenomenon involved in Hawking's radiation and similar.
