LScopedAsyncView<T> class

A widget that creates a synchronous scope but resolves its controller asynchronously.

LScopedAsyncView initializes the scope immediately with LScope, then uses LAsyncView to wait for async controller resolution.

In short:

  • Sync scope setup
  • Async controller resolution
Inheritance

Constructors

LScopedAsyncView({Key? key, LScopeDependencyFactory? dependencyFactory, Future<T> resolver(BuildContext context)?, Widget builder(BuildContext context, T controller)?, bool autoWatch = true, Widget loading(BuildContext context)?, Widget error(BuildContext context, Object error)?, List<Object?>? args, String? scopeName})
const
LScopedAsyncView.put(Future<T> create(), {Key? key, String? tag, bool permanent = false, bool isFactory = false, required Widget builder(BuildContext context, T controller), bool autoWatch = true, Widget loading(BuildContext context)?, Widget error(BuildContext context, Object error)?, List<Object?>? args, String? scopeName})
Shorthand for creating a scope, registering an async dependency, and consuming it.
factory
LScopedAsyncView.store(LevitAsyncStore<T> store, {Key? key, LScopeDependencyFactory? dependencyFactory, required Widget builder(BuildContext context, T controller), bool autoWatch = true, Widget loading(BuildContext context)?, Widget error(BuildContext context, Object error)?, List<Object?>? args, String? scopeName})
Syntax sugar for consuming a LevitAsyncStore within a new scope.
