You must be confused, or perhaps you're not talking about the same species that I am thinking about. Huckleberries, genus Gaylussacia, are definitely in the same family as blueberries, Vaccinium. They're both Ericaceae, in the subfamily Vaccinioideae. Gaylussacia is definitely not in Solanaceae.
Two species of blueberry as well as cranberry grow natively in a few bog habitats near my home, and huckleberries are also sympatric with these species.
ETA: I saw some context from other comments in this chain that somebody else already beat me to this. I, too, didn't realize that there were, if you were, "false" huckleberries in the nightshade family.
To add to both of our shared confusion, there is even a false huckleberry from within the blueberry family, but instead the Ericoideae subfamily: https://www.inaturalist.org/taxa/553849-Rhododendron-menziesii. I have no experience with this plant, or even really this subfamily, as it isn't exactly endemic to my neck of the woods.
