Episode - 21 Create a Route Information Parser

Now that our Navigation state is ready let us parse the infromation that we get from our navigation. We are going to use the RouteInformationParser for this. In the Router directory create a new file called as book_router_parser.dart and in this file create a BookRouterParser class which extends RouteInformationParser with our AppLink Type like this.

class BookRouterParser extends RouteInformationParser<AppLink>{}
  Future<AppLink> parseRouteInformation(
      RouteInformation routeInformation) async {
    final link = AppLink.fromLocation(routeInformation.location);
    return link;
  RouteInformation restoreRouteInformation(AppLink appLink) {
    final location = appLink.toLocation();

    return RouteInformation(location: location);
final bookRouterParser = BookRouterParser();
          routeInformationParser: bookRouteParser,
          backButtonDispatcher: RootBackButtonDispatcher(),
          routerDelegate: _bookRouterDelegate,
