Added #

• Enhanced Serialization Extensions: Major improvements to fromSerializable<T>() method

  • List<DateTime> support - Convert arrays of ISO strings, timestamps, and DateTime objects
  • List<Duration> support - Convert arrays of microsecond integers, strings, and Duration objects
  • Map<String, DateTime> support - Handle JSON objects with date fields
  • Map<String, Duration> support - Handle configuration objects with time values
  • Early error detection with assert() statements in debug mode
  • Comprehensive type validation with _isSupportedType() helper method

• Safe Conversion Helpers: New helper methods for robust type conversion

  • _safeDateTime() - Handles ISO strings, timestamps, with Unix epoch fallback
  • _safeDuration() - Handles microseconds, strings, with zero duration fallback
  • Graceful error handling for all invalid inputs

• Developer Experience Improvements:

  • Clear, detailed assert error messages guide developers to supported types
  • Immediate feedback during development for unsupported type usage
  • Better documentation in error messages with examples

Changed #

• Simplified Architecture: Removed complex recursive type conversion logic

  • Direct type checking for better performance and maintainability
  • Eliminated _extractGenericType() and _extractMapValueType() helper methods
  • Removed _convertToType() recursive method for cleaner code
  • Streamlined error handling with assert-first approach

• Improved Type Safety: Enhanced type checking and conversion

  • Fixed string-to-int conversion to handle decimal strings like "95.5" → 95
  • Better handling of mixed data types in collections
  • More robust JSON string parsing for typed collections

Fixed #

• Type casting issues with Map<String, DateTime> and Map<String, Duration>
• Decimal string parsing in _safeInt() method (e.g., "95.5" now converts to 95)
• Eliminated runtime UnsupportedError throws in favor of development-time asserts

Technical Details #

• Supported Simple Types: int, double, String, bool, DateTime, Duration, Uri, Object?, dynamic
• Supported List Types: List<int>, List<double>, List<String>, List<bool>, List<DateTime>, List<Duration>, List<Object?>
• Supported Map List Types: List<Map<String, Object?>>, List<Map<String, dynamic>>
• Supported Map Types: Map<String, int>, Map<String, double>, Map<String, String>, Map<String, bool>, Map<String, DateTime>, Map<String, Duration>, Map<String, Object?>, Map<String, dynamic>

Migration Notes #

• No breaking changes - all existing functionality preserved
• Assert statements only trigger in debug mode, no impact on production builds
• New DateTime/Duration collection support is additive
• Developers using unsupported nested types will now get immediate feedback via asserts
