I accidentally evolved my floette into a Florges and I was wondering if it can still learn level up moves or else is there another way to find another shiny stone in x so I can train up another one thank you and I hope you can answer my question.
In all seriousness, it doesn't look like it. On the serebii page for florges here, all the moves have a - next to it which I would assume means learnt at the start, or from a previous evolution. So you might want to go train another one or, if you have heart scales go to the Move Relearner in Dendemille Town to relearn what moves you would want.
