Standalone Angular Component has errors with AddinClientService and SkyThemeService

So I have been testing a little and created a new pared back application. It has one component that does nothing other than the default statement that the component works.

As soon as I added

constructor(clientService: AddinClientService){}

I got the previous error. I attempted to add the service to the app.config.ts file as below:

export const appConfig: ApplicationConfig = {
providers: [provideRouter(routes),
importProvidersFrom(AddinClientService)
]};

This did not help though. The error

NullInjectorError: No provider for _SkyThemeService

makes me think that it is not something that I am doing given that I am not directly referencing the SkyThemeService.

Just in case anybody should come across this thread and want to know how it was resolved, here is what @Michael Tims came up with as a workaround.

import { ApplicationConfig } from '@angular/core';
import { provideRouter } from '@angular/router';
import { SkyThemeService } from '@skyux/theme';
import { routes } from './app.routes';

export const appConfig: ApplicationConfig = {
providers: [
provideRouter(routes),
SkyThemeService
]
};

By adding the SkyThemeService to the providers array directly (and not using the importProvidersFrom function), the solution worked.

However, this may well change in the future as there ought not to be a need to add this as a reference when adding the AddinClientService which should encapsulate everything it needs.
