A pure-Dart language detection library for Dart and Flutter applications.

Changelog

0.1.0

Stable release

• Moved to Dart 3.13

0.1.0-dev.1

Initial development release of betto_lang_detector.

Features

• LanguageDetector.pureDart() — zero-dependency default: a Unicode script pre-filter plus a character n-gram model, covering 58 languages (matching betto_lexical's Stopwords set).
• LanguageDetector.detect(String text) — returns Detected (a best guess plus a ranked list) or Undetermined (nothing met the confidence threshold).
• LanguageDetector.dominantScript(String text) — cheap, script-only classification (ISO 15924 code) for tokenizer routing guard rails; does not run the n-gram stage.
• restrictTo — narrows the candidate language set, improving n-gram accuracy for callers who already know the plausible language set.
• Pure Dart, zero runtime dependencies — no FFI, no native build, works identically on web, mobile, and desktop.
