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
