Removes the popped page if the navigation was not user initiated and there is a page to be removed.

Implementation

bool removePoppedPageIfNotUserInitiated(String? removedPageName) {
  // If this page was marked to ignore (from Replace), ignore it
  if (removedPageName != null &&
      _pagesToIgnoreRemoval.contains(removedPageName)) {
    _pagesToIgnoreRemoval.remove(removedPageName);

    return false;
  }

  if (_isPerformingUserInitiatedNavigation ||
      _resolvedNavigationStack.length < 2) {
    return false;
  }

  // Check if dismiss is allowed
  final allowed = _canDismissCurrentPage();
  if (!allowed) {
    return false;
  }

  // Add the action to keep breadcrumb navigation.
  // Do not notify listeners to prevent duplicated navigation.
  const dismissAction = Dismiss();
  final canNavigate = _canNavigateFromCurrentPage(dismissAction);
  if (!canNavigate) return false;
  _commitNavigationStack(
    _resolveNavigationStack(dismissAction),
    dismissAction,
  );
  _trackNavigationAnalytics(dismissAction);

  // When the system removes a page (e.g. tapping outside a modal bottom
  // sheet), we still need to notify listeners so UI and view models that
  // depend on navigation state can react. Schedule it post-frame to avoid
  // potential duplicated removals while `Navigator` is already processing.
  SchedulerBinding.instance.addPostFrameCallback((_) {
    notifyListeners();
