beforeUpdate property
This is called before the url is updated, if this VRouteElement is in the previous route AND in the new route
Use vRedirector if you want to redirect or stop the navigation.
DO NOT use VRouter methods to redirect.
vRedirector also has information about the route you leave and the route you go to
Note that you should consider the navigation cycle to
handle this precisely, see https://vrouter.dev/guide/Advanced/Navigation%20Control/The%20Navigation%20Cycle
Also see:
- VRouter.beforeEnter for global level beforeEnter
- VRedirector to known how to redirect and have access to route information
Implementation
final Future<void> Function(VRedirector vRedirector) beforeUpdate;
