Fixed #

• Effects not stopped when scope stops - watchEffect and watch now properly register their effects with the current effect scope via registerWithScope(). Effects are now correctly stopped when their owning scope is stopped, preventing resource leaks and duplicate timers in Flutter apps.

• Code formatting issues across library and test files

Fixed #

• Code formatting issues across library and test files

Fixed #

• Updated README to reflect redus as dev utility package (not just reactivity)
• Added complete DI module documentation to CHANGELOG and README

Added #

• Dependency Injection Module (package:redus/di.dart)

  • register<T>(instance, {key}) - Register singleton with optional key
  • registerFactory<T>(factory, {key}) - Register factory with optional key
  • get<T>({key}) - Get registered instance by type and optional key
  • isRegistered<T>({key}) - Check if type/key is registered
  • unregister<T>({key}) - Remove registration
  • resetLocator() - Clear all registrations

• Key-based Lookup - Register multiple instances of same type with different keys

  register<Logger>(ConsoleLogger(), key: #console);
  register<Logger>(FileLogger(), key: #file);
  final log = get<Logger>(key: #console);
  

Changed #

• Package Scope Expanded - Redus is now a dev utility package with multiple modules:
  • package:redus/reactivity.dart - Fine-grained reactivity system
  • package:redus/di.dart - Dependency injection
  • package:redus/redus.dart - All modules combined

Added #

• Callable Ref and Computed - Both Ref<T> and Computed<T> now have a call() method
  • count() is equivalent to count.value
  • Allows Ref<T> and Computed<T> to be used as T Function()
  • Enables perfect type inference in watch() and other APIs

Changed #

• Strongly typed watch() API - Source is now T Function() instead of Object

  • Type inference works automatically: watch(count, (val, old, _) => ...) infers T as int
  • No more need for explicit watch<int>(...) calls
  • Both Ref and Computed work directly as sources (since they're callable)
  • Getter functions () => x.value also work with full inference

• Strongly typed watchMultiple() API - Sources are now List<T Function()>

Added #

• Flutter Integration Support
  • Exported ReactiveEffect class for custom effect creation
  • Exported activeEffect and effectStack for render tracking
  • Enables automatic UI reactivity in redus_flutter without manual watchEffect

Changed #

• Removed @internal annotations from activeEffect and effectStack

Added #

• Core Reactivity (src/reactivity/core/)

  • ref<T>() - Mutable reactive reference with .value accessor
  • computed<T>() - Lazily evaluated, cached computed values
  • writableComputed<T>() - Computed values with custom setters
  • readonly<T>() - Read-only wrapper preserving reactivity
  • watchEffect() - Immediate effect with dependency tracking
  • watchPostEffect() / watchSyncEffect() - Flush timing variants
  • watch() / watchMultiple() - Explicit source watching
  • onWatcherCleanup() - Register cleanup in effects
  • WatchHandle with stop(), pause(), resume()
  • Scheduler for batching with pre/post/sync flush modes

• Utilities (src/reactivity/utilities/)

  • isRef() - Check if value is Ref
  • unref<T>() - Unwrap ref or return value
  • toRef<T>() - Normalize value/getter to ref
  • toValue<T>() - Normalize ref/getter to value
  • toRefs<T>() - Convert map to refs
  • isProxy() / isReactive() / isReadonly() - Type checking

• Advanced (src/reactivity/advanced/)

  • shallowRef<T>() - Shallow reactive ref (no deep tracking)
  • triggerRef() - Force trigger shallow ref
  • shallowReadonly<T>() - Shallow readonly wrapper
  • customRef<T>() - Custom ref with track/trigger control
  • toRaw<T>() - Get underlying value from reactive
  • markRaw<T>() / isMarkedRaw() - Prevent reactivity
  • effectScope() - Group effects for disposal
  • getCurrentScope() - Get active effect scope
  • onScopeDispose() - Register scope cleanup

Package Structure #

Reorganized into three modules:

• core/ - Core reactive primitives and effects
• utilities/ - Helper functions
• advanced/ - Advanced features
