A next-level FlutterFlow fuzzy search widget for ultra-fast, typo-tolerant lookup across huge lists and object collections. V3 adds multi-field weights, proximity/token scoring, synonyms & stop-words, locale/diacritics handling, and rich highlight ranges — delivering instant, ranked results without blocking your UI. 🚀

Functionality ✨

• 🗂 List<String> / List<Map> support with dot-path keys

• ⚖️ Per-key weights + global boosts (exact / prefix / substring / token)

• ✍️ Typo tolerance (max edit distance), token proximity, phrase bias

• 🧪 Tunables: threshold, limit, offset, caseSensitive, diacritics, locale

• 🧠 Synonyms & stopWords lists; include/exclude filters, item pinning

• 🏅 Returns ranked results with scores, match ranges (for highlighting), and indices

• 🔮 Preview/stream mode for keystroke-by-keystroke suggestions

• 📊 Stable sort with tie-breakers; optional recency/popularity boosts

• 🔁 Deduplicate by key + collapse duplicates via aggregator callback

• 🧵 Non-blocking execution (worker isolate) with cancellable runs

• ⚡ Smart caching & optional prebuilt index (eager/lazy)

• 🛡️ Error/empty guards & safe defaults for giant datasets

• 🔌 Drop-in bindings for inputs, typeahead, lists, and pickers

• 🎨 Fully themable highlight formatting via exposed ranges

Use cases 🧩

• 🧭 Global app search / command palettes across multi-field records

• 🛒 Catalogs (products/movies/books) with title, tags, author/brand fields

• 👥 CRM directories (name, company, email, phone)

• 📚 Knowledge base & docs search with synonyms + phrase proximity

• 🛠 Admin tools: settings/logs/feature-flag finders across keys

• 🌍 Country/city/tag pickers powering long single/multi-selects

• ✈️ Offline catalogs (travel/POS/media) with on-device prebuilt index

• ✍️ Autocomplete/typeahead backends for forms, chats, editors

• 📈 Analytics builders: metrics/dimensions/segments quick-find

• 🏢 Enterprise search where ranking & highlight quality matter
