CanDeactivate class abstract
A lifecycle interface that allows conditionally deactivating a route.
Routed components should implement this to prevent deactivation based on the next RouterState. Prefer CanNavigate if the next RouterState isn't needed.
This interface is checked after constructing the components necessary to resolve the next RouterState.
An example use case is preventing deactivation if the current and next route haven't changed, but navigation was triggered for another reason such as an added query parameter.
