Inject ComponentRef into Component created by ComponentFactory with custom Injector
I want to create a component using ComponentFactory. I want to use a custom injector to provide some objects to that component. Furthermore i need the ComponentRef of the newly created Component because i want to use its destroy function. How can i get the ComponentRef?
I cannot provide it via the custom injector since it is not declared at the time the injector is created.
Until now i worked around that problem by providing an arrow function which returns the componentRef when needed but that solution feels ugly. I hope a better solution exists.
i prepared a simple stackblitz example with the relavant code here: https://stackblitz.com/edit/angular-kxws7v

You can do what I did when I wanted to "destroy" the component. You can send function into the component and use it to destroy from out side(from the service). You can use @Input/Output()
