Building Design Tools with Flutter
summary
A working prototype called Flva embeds Figma nodes as Flutter widgets on an infinite canvas and supports selection, drag, zoom (mouse + modifier), and keyboard shortcuts. The main claim is that Flutter handles professional design-tool complexity; the implementation replaces tangled ifs with an explicit state machine for mouse down/move/up, tool changes and focus, making interactions deterministic, testable and framework‑portable. The author plans a reusable package for this state-driven interaction model.
