## Packages (15 on pub.dev)

### On-Device AI
- **ai_core_codespark** — Core embedding engine with offline MiniLM model, utilizing isolates to ensure heavy computation never blocks the UI thread.
- **semantic_search_codespark** — Query-driven semantic search with debounced input and MMR diversity ranking, optimized for memory-efficient large dataset processing.
- **smart_suggestions_codespark** — Anchor-based recommendations with MMR diverse ranking and centroid matching, designed for low-overhead, low-latency execution.

### Text & UI
- **text_comparison_score_codespark** — String similarity using Levenshtein, Damerau-Levenshtein, and Jaro-Winkler algorithms, heavily optimized for large text blocks.
- **text_highlight_codespark** — Text highlighting with single, multiple, and regex query support, leveraging TextSpan to avoid expensive widget tree rebuilds.
- **rich_highlight_text_codespark** — Inline substring highlighting using Text.rich and custom styles for zero-overhead text rendering.
- **dual_tone_text_codespark** — Dual-tone gradient text rendering built with an optimized CustomPainter to minimize layout passes and repaints.
- **curved_text_codespark** — Render text along complex paths (circular, spiral, wave) using low-level canvas operations for 60fps performance.
- **date_formatter_codespark** — Lightweight DateTime extensions for relative time and business day calculations without heavy dependencies.
- **animated_dropdown_search_codespark** — Customizable search dropdown utilizing heavily optimized animation controllers to prevent layout jank.
- **read_more_codespark** — Expandable text widget that efficiently measures TextPainters in memory to calculate truncations without forcing extra layout passes.
- **icon_to_text_extension_codespark** — Convert IconData directly to inline TextSpan, reducing widget tree depth and improving rendering efficiency.

### Developer Utilities
- **advanced_text_input_formatters_codespark** — Extended input formatters optimized for low-latency text evaluation on every keystroke.
- **internet_quality_codespark** — Measure real-world internet quality using low-overhead latency-based analysis rather than expensive bandwidth hogs.
- **context_extensions_codespark** — Build context utility extensions that reduce boilerplate and ensure safe, `O(1)` inherited widget lookups.
