didChangeNext method

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

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) {
  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);
}
