Answer 1

Finally I have found the solution: https://angular.io/guide/providers#providedin-and-ngmodules Service also should be mentioned in the providers section of module.

  imports: [CommonModule],
  declarations: [DashboardComponent],
  exports: [DashboardComponent],
  providers: [DashboardService]
})

Demo has been corrected. Thank you guys!
