FlutterFlow search widget — lightning-fast, on-device fuzzy search for huge lists ⚡🔎. Filter and rank massive string arrays in real time with keystroke-by-keystroke hints. Tweak relevance 🎯 with a similarity threshold, control case sensitivity 🔠, hard-limit results 🚦, and stream instant previews while typing. Lightweight, offline-friendly, and perfect for crisp, accurate search across big data on mobile & web.
