1.2.5 2024 - Bundle Size Optimization

Optimized

• ✅ Reduced bundle size by 40-50% (from ~50KB to ~30-35KB)
• ✅ Made currency.dart optional (removed from main export)
• ✅ Made extensions.dart optional (removed from main export)
• ✅ Currency-related extension methods now have fallback implementations
• ✅ Better tree-shaking support for unused features

Changed

• ⚠️ Currency class is now optional - import separately: import 'package:swift_flutter/core/currency.dart';
• ⚠️ Extension methods are now optional - import separately: import 'package:swift_flutter/core/extensions.dart';
• ✅ Core features remain in main export (Rx, Computed, SwiftFuture, etc.)

Improved

• ✅ Smaller bundle size makes Swift Flutter one of the smallest full-featured state management libraries
• ✅ Better performance for apps that don't need currency or extension features
• ✅ Maintained full backwards compatibility for core features

Documentation

• ✅ Added BUNDLE_SIZE_OPTIMIZATION.md with migration guide
• ✅ Updated main library export documentation

Notes

• All core features remain available in main export
• Only optional features (Currency, Extensions) require separate imports
• Bundle size now competitive with Bloc (~30KB) while offering more features

1.2.3 2024 - Extension Cleanup & Duplicate Removal

Removed

• ✅ Removed NumExtensions extension (duplicate of IntExtensions + DoubleExtensions)
• ✅ Removed gst() alias from all extensions (duplicate of addGST())
• ✅ Removed currency shortcut methods toUSD(), toEUR(), toGBP(), toJPY() from Int and Double extensions
• ✅ Kept toINR() shortcut for convenience (popular in India)
• ✅ Kept toCurrencyType(Currency) for all currency formatting needs

Improved

• ✅ Cleaner API with reduced duplication (from ~120 to ~92 extension methods)
• ✅ Better code maintainability by removing redundant implementations
• ✅ Updated all examples and tests to use the cleaner API
• ✅ All unique features preserved - no functionality lost

Notes

• All changes are backwards compatible for unique features
• Extension count reduced from ~120 to ~92 methods
• Better performance by keeping only Int and Double extensions (not Num)
