addSingleton<T> method

@override void addSingleton<T>(Function constructor, { BindConfig<T>? config, String? key, })

Register a Singleton instance. It will generate a single instance for the duration of the application, or until manually removed.
The object will be started as soon as it is registered.

injector.addSingleton(MyController.new);

When [key] is provided this instance only can be found by key

}) {

    config: config,
    key: key,
