How hhdblog/dev_hud works
DevHud is a Flutter debug overlay. The documented workflow is to wrap an app with DevHud, publish custom values through the singleton DevHudService, and inspect those values alongside FPS in the overlay. The widget also documents memory display, draggable placement, copy-on-long-press, collapsible groups, and optional position persistence. Source excerpts were unavailable, so the graph uses only README-documented relationships and does not infer internal calls or storage details.
