didChangeNext method

  1. @override
void didChangeNext(
  1. Route? nextRoute
)
override

This route's next route has changed to the given new route.

This is called on a route whenever the next route changes for any reason, so long as it is in the history, including when a route is first added to a Navigator (e.g. by Navigator.push), except for cases when didPopNext would be called.

The nextRoute argument will be null if there's no new next route (i.e. if isCurrent is true).

Implementation

@override
void didChangeNext(Route<dynamic>? nextRoute) {
  if (nextRoute is ModalRoute<T> && canTransitionTo(nextRoute) && nextRoute.delegatedTransition != this.delegatedTransition) {
    receivedTransition = nextRoute.delegatedTransition;
  } else {
    receivedTransition = null;
  }
  super.didChangeNext(nextRoute);
  changedInternalState();
}
