solid_x 2.1.0

Inspired by Kotlin's `ViewModel + StateFlow` pattern, Solid provides a clean architecture to manage your application's state with zero code generation and zero boilerplate.

2.1.0

• Added: Mutation<T> — a reactive wrapper around async functions that automatically tracks initial → loading → success / empty / error lifecycle, with zero manual state management.
• Added: mutation<T>(fn) helper on Solid — throw-based, declares a mutation in one line inside a ViewModel.
• Added: mutationEither<L, T>(fn) helper on Solid — Either-based, compatible with dartz Either<L, R>, Left maps to error state, Right maps to success.
• Added: MutationBuilder<T> widget — renders the correct widget per mutation state with optional onSuccess/onError side-effect hooks and buildWhen filtering.
• Added: MutationState<T> sealed class with 5 subtypes: MutationInitial, MutationLoading, MutationSuccess, MutationEmpty, MutationError.
• Updated: Example app — new Mutation tab (⚡) demonstrating all mutation variants.

2.0.3

• Major Redesign: Solid is now a StateFlow/ViewModel pattern library.
• Added: SolidViewModel<S> – single-state ViewModel base class with emit(S).
• Added: SolidConsumer<T> – combines SolidBuilder and SolidListener in one widget.
• Removed: Granular state management (SolidState, Mutation, Solid base class).
• Simplified: The widget API (SolidProvider, SolidBuilder, SolidListener) now supports any ChangeNotifier.
• Updated: Added context.solid<T>() extension for easy ViewModel lookup.

1.0.0

• Initial release.
• Granular state management with SolidState<T> and Mutation<T>.
• Solid abstract base class with auto-disposal.
• 8 widget variants for state and mutations.
