dvHostedLocation function

String? dvHostedLocation(String location, List<RouteBase> routes, { String at = '/', })

The Dartvel path a host location names under at, or null when it is not one of routes: the host's own route, which the host handles.

Implementation

String? dvHostedLocation(
  String location,
  List<RouteBase> routes, {
  String at = '/',
}) {
  final Uri uri = Uri.parse(location);
  String path = uri.path.isEmpty ? '/' : uri.path;
  if (at != '/') {
    if (path == at) {
      path = '/';
    } else if (path.startsWith('$at/')) {
      path = path.substring(at.length);
    } else {
      return null;
    }
  }
  final bool ours = dvRoutePaths(routes)
      .any((String pattern) => dvRoutesOverlap(path, pattern));
  if (!ours) return null;
  return uri.replace(path: path).toString();
}
