How to check which the current Route is?

Navigator doesn’t expose the current route.

What you can do instead is use Navigator.popUntil(callback) as popUtil pass to the callback the current Route, which includes it’s name and stuff.

final newRouteName = "/NewRoute";
bool isNewRouteSameAsCurrent = false;

Navigator.popUntil(context, (route) {
  if (route.settings.name == newRouteName) {
    isNewRouteSameAsCurrent = true;
  }
  return true;
});

if (!isNewRouteSameAsCurrent) {
  Navigator.pushNamed(context, newRouteName);
}
