I don't think the Ju-87's gull wing was dictated by the carrier capability. Indeed, the RLM only started studying for the type for the carrier in 1937, several years after design and first flight of the first prototype (which as a point of historical interest had a twin tail).
Rather, the gull wing improved pilot visibility, provided greater ground clearance for the prop (important given its expected use from unprepared airstrips), and allowed more rapid reloading of bombs due to the easier access.
Nevertheless, the Ju87C carrier variant is one of the lesser known aspects of the Stuka story.
