didChangeNext method
- @override
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. nextRoute will be null if there's no next route.
Implementation
@override
void didChangeNext(Route<dynamic> nextRoute) {
assert(_controller != null, '$runtimeType.didChangeNext called before calling install() or after calling dispose().');
assert(!_transitionCompleter.isCompleted, 'Cannot reuse a $runtimeType after disposing it.');
_updateSecondaryAnimation(nextRoute);
super.didChangeNext(nextRoute);
}
