🎉 Major Release - Production-ready with comprehensive improvements and new features!

🔴 Fixed (Critical) #

• Fixed memory leak in addListener: Listeners are now properly invoked when reactive values change
• Fixed memory leak in bindStream: Stream subscriptions are now properly managed and cancelled
• Fixed Observer widget performance: Now uses optimized value parameter instead of redundant lookups
• Removed unnecessary async keywords: Methods addListener() and removeListener() are now synchronous

⚡ Performance #

• Batched updates for ReactiveList: Multiple mutations in the same frame trigger only one rebuild
• Batched updates for ReactiveSet: Same batching strategy to prevent excessive rebuilds
• Optimized Observer rebuilds: Eliminated unnecessary value access in widget builders

✨ New Features #

State Management

• Undo/Redo support: Enable history tracking with enableHistory: true parameter
  • Methods: undo(), redo(), canUndo, canRedo, clearHistory()
  • Configurable history size with maxHistorySize parameter (default: 50)
• Computed reactive values: New ComputedReactive<T> class for auto-updating derived state
• Debounce support: Delay updates with setDebounce() and updateDebounced() methods
• Throttle support: Limit update frequency with setThrottle() and updateThrottled() methods
• Ever & Once utilities: Convenient listener methods
  • ever(callback) - called on every value change
  • once(callback) - called once then auto-removed

Dependency Management

• Lazy dependency injection: Dependency.lazyPut<T>() for deferred instantiation
• Put with overwrite: put() now overwrites existing dependencies with warning
• Conditional registration: New putIfAbsent() method
• Dependency checking: New isRegistered<T>() method
• Global reset: New reset() method to clear all dependencies
• Fenix mode: Auto-recreation after deletion with fenix: true parameter

🛠️ Improvements #

Code Quality

• Custom exceptions: New exception classes with helpful error messages
  • DependencyNotFoundException
  • DependencyAlreadyExistsException
• Explicit return types: All methods now have proper return type declarations
• Fixed typo: Corrected "associa ted" to "associated" in documentation

Developer Experience

• Configurable logging: Control logging with Logger.enabled flag
• Warning and error logs: New Logger.warn() and Logger.error() methods
• Better error messages: All exceptions provide clear, actionable information
• Stream subscription management: bindStream() now returns StreamSubscription for external control

📚 Documentation #

• NEW_FEATURES.md: Comprehensive guide to all new features with examples
• QUICK_REFERENCE.md: Quick-start guide for common use cases
• IMPLEMENTATION_SUMMARY.md: Technical implementation details
• Advanced example: New advanced_features_example.dart demonstrating all features

🔄 Changed #

• All reactive types (ReactiveInt, ReactiveString, etc.) now support optional parameters:
  • enableHistory - Enable undo/redo functionality
  • maxHistorySize - Configure history buffer size
• ReactiveN class updated to support new optional parameters
• Dependency.put() behavior changed to overwrite with warning (previously silently ignored)
• bindStream() now returns StreamSubscription instead of void

⚠️ Deprecated #

None - All changes are backward compatible!

🚫 Breaking Changes #

None! Version 1.0.0 maintains full backward compatibility with 0.3.x versions.

📦 Migration Guide #

No migration needed! All new features are opt-in. To use them:

1. Enable logging control:

   Logger.enabled = false; // Disable in production
   

2. Use history tracking:

   final text = ReactiveString('Hello', enableHistory: true);
   

3. Create computed values:

   final fullName = ComputedReactive(
     () => '${firstName.value} ${lastName.value}',
     [firstName, lastName],
   );
   

4. Use lazy dependencies:

   Dependency.lazyPut(() => MyController());
