rapideTicketNavigatorContextForOverlay function

BuildContext? rapideTicketNavigatorContextForOverlay(BuildContext scope)

Context suited for Navigator.push / RapideTicket.showFeedback: first Navigator.maybeOf, else first NavigatorState in scope's subtree.

Needed when this widget sits above Navigator (e.g. return from MaterialApp.builder): the scope BuildContext then has no Navigator ancestor.

Implementation

BuildContext? rapideTicketNavigatorContextForOverlay(BuildContext scope) {
  final fromAncestor = Navigator.maybeOf(scope);
  if (fromAncestor != null && fromAncestor.mounted) {
    return fromAncestor.context;
  }
  final Element? el = scope as Element?;
  if (el == null) return null;
  final found = _findNavigatorStateInSubtree(el);
  if (found != null && found.mounted) {
    return found.context;
  }
  return null;
}
