Static Methods

create<S>(InstanceCreateBuilderCallback<S> builder, {String? tag, bool permanent = true}) → Bind

Deletes a dependency from the GetX service locator using the specified tag.
deleteAll({bool force = false}) → Future<void>
Deletes all dependencies from the GetX service locator.
find<S>({String? tag}) → S
Retrieves a dependency from the GetX service locator using the specified tag.
isPrepared<S>({String? tag}) → bool
Checks if a dependency is prepared in the GetX service locator using the specified tag.
isRegistered<S>({String? tag}) → bool
Checks if a dependency is registered in the GetX service locator using the specified tag.
lazyPut<S>(InstanceBuilderCallback<S> builder, {String? tag, bool fenix = true, VoidCallback? onClose}) → Bind
Creates a lazy binding and puts the specified dependency into the GetX service locator.
lazyReplace<P>(InstanceBuilderCallback<P> builder, {String? tag, bool? fenix}) → Future<void>
