mvvm_service 2.2.0

A Flutter-native MVVM service layer that creates, loads, watches, shares, and disposes services according to the widget lifecycle.

1.0.0

• Initial version.

1.0.1

• Modified ServiceBuilder<T> to automatically load its service only if it hasn't been initialized yet.

1.0.2

• Fixed an issue where services could not be referenced due to incorrect generic type handling.

1.1.0

• Added ServiceWhen<T> extension on services to declaratively build widgets based on their current state.

• Updated ServiceBuilder<T> to dispose its Service instance when the widget is disposed if it fully owns the service.

1.1.1

• Added ServiceWidgetOf, a widget that allows referencing an existing service from the widget tree. This widget is useful when a service has already been initialized and managed by an ancestor widget, allowing descendant widgets to access and rebuild in response to service updates without creating a new instance.

1.1.2

• Fixed the issue where ServiceWidget<T> and ServiceWidgetOf<T> could not correctly reference an ancestor service due to ServiceProvider not having an explicit generic type, ensuring descendant widgets can now access the service with the proper type.

2.0.0

Breaking Changes

• Replaced ServiceProvider with a single root ServiceScope.
• Removed ServiceWidget and ServiceWidgetOf.
• Removed ServiceContainer and all multi-service container APIs.
• Removed Service.of() and Service.maybeOf().
• Services are now lazily created through BuildContext.serviceOf().
• Added automatic service sharing, watching, loading, and lifecycle disposal.
• Added ServiceMode.read and ServiceMode.watch.

2.1.0

• Added an optional key parameter to BuildContext.serviceOf(), allowing multiple independently configured instances of the same service type.
• Added and exported ServiceId to identify services by their type and optional key.

2.2.0

• Added BuildContext.stateOf() for creating reactive state backed by ValueNotifier.
• Added StateScope and the ServiceScope.withState convenience constructor.
• Added StateMode.read and StateMode.watch to control widget rebuilds.
• Added automatic state identity based on type and invocation order, with optional keys for explicit sharing or separation.
• Added an onDispose callback for cleaning up resources held by state values.
• Added automatic disposal when a state no longer has dependent elements.
