safe_text 2.1.0

A Flutter package for filtering out bad words from text inputs and detecting phone numbers in various formats including multiplier words.

2.1.0

Added

• MaskStrategy API: New sealed class with three strategies for controlling how profanity is masked:
  • MaskStrategy.full({obscureSymbol}) — replaces every character (e.g. "badass" → ``"******"`).
  • MaskStrategy.partial({obscureSymbol}) — keeps first (and last, for 4+ char words) visible (e.g. "damn" → "d**n").
  • MaskStrategy.custom({replacement}) — replaces the entire word with a fixed string (e.g. "[censored]").
• strategy parameter on SafeTextFilter.filterText and the deprecated SafeText.filterText to accept a MaskStrategy.

Changed

• Legacy fullMode and obscureSymbol parameters on filterText are now deprecated in favour of MaskStrategy. Existing call sites continue to work unchanged.
• MaskStrategy is exported from the top-level safe_text.dart barrel file.

2.0.1

Documentation

• Rewrote README with pub.dev badges, full API reference tables, supported languages list, migration guide from v1.x, How it Works section, and Limitations section.
• Fixed CHANGELOG entries for 1.0.5–1.0.7: corrected Added category to Fixed/Changed for bug fix and refactor entries.

2.0.0

Added

• Aho-Corasick Engine: Replaced legacy regex loops with a high-performance Trie-based search engine for O(N) search complexity.
• Extreme Performance: Up to 20x faster for large pattern sets and mixed language inputs.
• Flexible Initialization: SafeTextFilter.init now supports either a single language or a list of languages for custom combinations.
• Multilingual Support: Support for 75+ languages with full names (e.g., Language.english, Language.hindi).
• Modular API: Separated functionality into SafeTextFilter for profanity and PhoneNumberChecker for phone detection.
• Single-Pass Replacement: Optimized string building avoids multiple copies during filtering.

Deprecated

• SafeText Class: The monolithic SafeText class is now deprecated. Use SafeTextFilter and PhoneNumberChecker directly for better performance and modularity.
