[Navigation] Lifecycle Interfaces

[dansiegel]

What would you like to be added:

Add Navigation Lifecycle interfaces similar to what you see in Prism. This would be helpful across all programming paradigms (MVVM & MVUX) where you can make a single navigation call and pass state which can be responded to properly in the View's DataContext regardless of what pattern it follows.

public interface INavigationAware
{
    void OnNavigatedFrom(NavigationState state);
    void OnNavigatedTo(NavigationState state);
}

public enum NavigationType
{
    New,
    Back
}

public interface IParameters : IEnumerable<string, object>
{
    void Add(string key, object value);
    T Get<T>(string key);
    bool TryGet<T>(string key, T value);
}

public record NavigationState(NavigationType Type, IParameters Parameters);

Why is this needed

Currently if I am going to Navigate to a given View and I need to update it's state, I must both write code to do the navigation and also trigger some sort of PubSubEvent that can be listened to. This is overly complex and can be greatly simplified by simply providing a common approach with interfaces that doesn't care about the Presentation layer's model (MVVM/MVUX) and simply requires less code from the developer as they can now simply Navigate and pass the state which can then be passed to a known method where they can perform their own custom updates and handle what they need to.
