Flutier is derived from "flute" (from Old French *flûte*, meaning a type of wind instrument) and the suffix "-ier" (meaning one who). Thus, a flutier is one who plays the flute.
Think of someone who plays a 'flute' — the '-ier' indicates a person, so a flutier is simply a person who plays the flute.
