routerDelegate property Null safety
final
The router delegate for the router.
This delegate consumes the configuration from routeInformationParser and builds a navigating widget for the Router.
It is also the primary respondent for the backButtonDispatcher. The Router relies on RouterDelegate.popRoute to handle the back button.
If the RouterDelegate.currentConfiguration returns a non-null object, this Router will opt for URL updates.
Implementation
final RouterDelegate<T> routerDelegate;
