GoRouter is a crucial tool for Flutter developers who want to design streamlined and effective navigation flows for their mobile apps. Any serious Flutter developer should have it because of its simplicity, flexibility, and robust community support.

Implementation

You will discover implementation in this section and how to use it in your Flutter app development. The first step in integrating go_router into your app is to add MaterialApp.router in its spot. Many attributes, including routeInformationParser and routerDelegate, are accepted by this function Object() { [native code] }.

MaterialApp.router(
  debugShowCheckedModeBanner: false,
  routeInformationParser:
  NyAppRouter.returnRouter(false).routeInformationParser,
  routerDelegate: NyAppRouter.returnRouter(false).routerDelegate,
);

Then we make an app_route_config.dart. We cover every path in this file. The default path, which is the home page, is added first. We append the name “path ad pageBuilder” to the routes section. After that, we build a route for the profile page and send the userId and userName along. For the reach us and about pages, we also develop GoRoute.

class NyAppRouter {
  static GoRouter returnRouter(bool isAuth) {
    GoRouter router = GoRouter(
      routes: [
        GoRoute(
          name: MyAppRouteConstants.homeRouteName,
          path: '/',
          pageBuilder: (context, state) {
            return const MaterialPage(child: Home());
          },
        ),
        GoRoute(
          name: MyAppRouteConstants.profileRouteName,
          path: '/profile/:username/:userid',
          pageBuilder: (context, state) {
            return MaterialPage(
                child: Profile(
                  userid: state.params['userid']!,
                  username: state.params['username']!,
                ));
          },
        ),
        GoRoute(
          name: MyAppRouteConstants.aboutRouteName,
          path: '/about',
          pageBuilder: (context, state) {
            return const MaterialPage(child: About());
          },
        ),
        GoRoute(
          name: MyAppRouteConstants.contactUsRouteName,
          path: '/contact_us',
          pageBuilder: (context, state) {
            return const MaterialPage(child: ContactUS());
          },
        )
      ],
      errorPageBuilder: (context, state) {
        return const MaterialPage(child: ErrorPage());
      },
    );
    return router;
  }
}

Additionally, introduce errorPageBuilder, a function Object() { [native code] } that accepts an ErrorPage as a child and returns MaterialPage. and delivers the modem back. We design the paths for navigators in this manner.

Additionally, we develop the GoRouters’ route variables. Wherein we send a string containing every route.

class MyAppRouteConstants {
  static const String homeRouteName = 'home';
  static const String aboutRouteName = 'about';
  static const String profileRouteName = 'profile';
  static const String contactUsRouteName = 'contact_us';
}

Finally, we build the project’s user interface (UI), during which we also learn about the go_router and UI navigation. We pass the app bar, where we pass the title and return the scaffold inside the house. Add the buttons that allow us to move from one page to the next after the Column in the body.

There are numerous ways to navigate, such as push and pushNamed, where we pass parameters like username and user-id, or we can pass the path of the route we have already defined in the route_config.dart file. This is how we employ go_router. I hope you pick up many new skills, like quickly passing parameters and creating paths or routes.

And that’s it! With these steps, you can easily implement navigation in your Flutter app using GoRouter. Of course, there are many more features and options you can use with GoRouter, such as URL-based routing and parameterized routing, so be sure to check out the documentation for more information.

GoRouter Dynamic Routes

GoRouter is a well-liked library for managing routes and switching between screens in Flutter apps. Dynamic routes, which allow developers to build routes based on information fetched from a server or user input, are one of its most potent features.

static home([CurrentTab? type]) => ‘/${type?.name ?? ‘:type’}’;
// static const singleArticleWithParams = ‘/article/:id’;
/// get route name with parameters, here [id] is optional because we need [:id] to define path on [_singleArticleWithParams]
static singleArticleWithParams([String? id]) => ‘/article/${id ?? ‘:id’}’;

Applications with changeable content or user-generated content, like social media or e-commerce apps, benefit greatly from dynamic routes. Instead of having to define routes and screens in preparation for their app’s navigation configuration, developers can create them instantly using dynamic routes.

The GoRouterState.add method, which accepts a route name and a route builder function as arguments, can be used by developers to make a dynamic route with GoRouter. Once the route has been navigated, the route builder function is responsible for developing the real widget that will be visible on the screen.

Consider an e-commerce app where tapping on a product in a list triggers the show of product details on a separate screen. Using GoRouter, you can construct a dynamic route for each product by using its unique identifier as the route name and retrieving the product details from a server in the route builder function. As a result, you can provide users with up-to-date product information without specifying a unique path for every product in your app’s navigation configuration.

Dynamic routes can be made based on user input and retrieving data from a server. For instance, you could designate a dynamic path for a user’s search query or profile data.

static Widget errorWidget(BuildContext context, GoRouterState state) => const NotFoundPage();

In general, dynamic routes are a strong component of GoRouter that lets developers build more adaptable and dynamic applications. Developers can create apps more responsive to user input and changing data and offer a more seamless and intuitive user experience by enabling routes to be made on the fly.
