Crafting OS-Level Experiences with Flutter Desktop
summary
Claim: Flutter Desktop can reach the OS layer and behave like a native utility. The demo builds a floating global Shift+Space palette that runs as a background tray app (window_manager, flutter_acrylic, tray_manager, desktop_multi_window, hotkey_manager), spawns an Olama server via Dart Process API for offline LLM answers, extracts the OS accent color via platform channels for theming, and converts DOCX to markdown using DOCX→Markdown via Rust FFI called from Dart. The prototype runs end‑to‑end (minor demo glitches noted) and returns contextual answers using Olama local LLM.
