Returns a new instance of RouteMatchList with the input match removed from the current instance.

Implementation

RouteMatchList remove(RouteMatchBase match) {
  final List<RouteMatchBase> newMatches = _removeRouteMatchFromList(matches, match);
  if (newMatches == matches) {
    return this;
  }

  final String fullPath = _generateFullPath(newMatches);
  if (this.fullPath == fullPath) {
    return copyWith(matches: newMatches);
  }

  if (newMatches.isEmpty) {
    return RouteMatchList.empty;
  }

  RouteBase newRoute = newMatches.last.route;
  while (newRoute is ShellRouteBase) {
    newRoute = newRoute.routes.last;
  }
  newRoute as GoRoute;
  // Need to remove path parameters that are no longer in the fullPath.
  final newParameters = <String>[];
  patternToRegExp(fullPath, newParameters, caseSensitive: newRoute.caseSensitive);
  final Set<String> validParameters = newParameters.toSet();
  final newPathParameters = Map<String, String>.fromEntries(
    pathParameters.entries.where(
      (MapEntry<String, String> value) => validParameters.contains(value.key),
    ),
  );
  final Uri newUri = uri.replace(path: patternToPath(fullPath, newPathParameters));
  return copyWith(matches: newMatches, uri: newUri, pathParameters: newPathParameters);
