Dependency class

An InheritedWidget that provides a DependencyProvider to the widget tree.

Wrap your app (or a subtree) with Dependency to make dependencies available via Dependency.of.

Dependency(
  dependencyProvider: provider,
  child: MyApp(),
);

// Later, in any descendant widget:
final api = Dependency.of<AppState, AppAction, AppEnv>(context)
  .resolve<ApiClient>();
