I have a simple system where I have a login component, a login service, a info component (containing info about the user) and an info service.

The idea I have is to get the login component to send the usr/pwd to the login service and if it comes back with 'true' (i.e. valid credentials) the app swaps out the login component for the info component and populates it with that user's data (this being from `<router-outlet></router-outlet>`).

I'm changing the component by `this.router.navigate(["farmer"])` - how do I pass in a string containing the name of the farmer too? (this will be the username they log in with).
