how can I change value of validCompo from other component please? Some people speak about Angular service to resolve that, but i don't understand how it works.. I have tried lot of things but nothing works...
Is it possible to show me on the example below the good way to resolve ?

Thanks a lot!
Have the variable defined in the service. Inject the service in both components. In the event handler, update the variable in service, it will reflect in both places.
