Flutter Navigation Made Easy: GoRouter vs AutoRoute (Which One Should You Use?)

Estimated reading time: 13 minutes

Navigation feels simple until it isn't. Push, pop, deep links, nested routes, guarded routes, code generation — suddenly your routing layer becomes the part of the app that needs the most care. Two popular libraries, GoRouter and AutoRoute, tackle these problems differently.

In this guide I'll compare both libraries from a practical, senior-developer perspective: when to pick one, how they differ in mental model, real-world tradeoffs, and concrete examples you can copy into your project.

This is a pragmatic guide, not a vendor fight. I'll show you patterns, pitfalls, and recommendations so you can make a confident decision that suits your team and app needs.

Overview

GoRouter is a routing solution created by the Flutter team that focuses on a simple declarative API and strong support for deep linking, redirection, and URL-based navigation. It aims to be easy to adopt while covering common routing needs.

AutoRoute is a powerful, code-generation-based routing solution that emphasizes compile-time safety, strongly typed arguments, nested routers, and a rich feature set. It leans into generated code to reduce boilerplate at runtime.

Both libraries are mature and well-maintained. The decision usually boils down to your priorities: simplicity and first-class web/deeplink support (GoRouter) vs advanced type-safety and complex nested routing (AutoRoute).

Causes/Reasons You Might Choose One Over the Other

Here are the core reasons teams pick one library over the other — think of these like decision signals for your project.

Choose GoRouter when:

• You want a simple declarative API that maps well to URL paths and deep links.
• Your app is web-first or needs strong URL synchronization between browser and app.
• You prefer minimal setup and less generated code to maintain.
• You value built-in redirection and authentication guard flows that are easy to reason about.

Choose AutoRoute when:

• You need compile-time safety for route arguments and strongly typed navigation.
• Your app has complex nested navigation (multiple nested routers or shell routes).
• You like code generation that creates a central router with typed route classes.
• Your team prefers explicit route classes over string-based paths for discoverability and refactorability.

Step-by-step Guide

Below are quick-start steps and a minimal example for each library so you can experiment fast.

GoRouter — Quick Start

1. Add the package: go_router to pubspec.yaml.
2. Wrap your app with MaterialApp.router and provide a GoRouter instance.
3. Define routes using a declarative list with path strings, builders, and optional redirect logic.

Minimal GoRouter example:

final router = GoRouter(
  routes: [
    GoRoute(
      path: '/',
      builder: (ctx, state) => HomePage(),
    ),
    GoRoute(
      path: '/profile/:id',
      builder: (ctx, state) {
        final id = state.params['id'];
        return ProfilePage(userId: id!);
      },
    ),
  ],
);

void main() {
  runApp(MaterialApp.router(routerConfig: router));
}

AutoRoute — Quick Start

1. Add auto_route and auto_route_generator, plus build_runner to your dev dependencies.
2. Annotate your routes in a single file using @MaterialAutoRouter and run code generation.
3. Use the generated AppRouter and typed route classes for navigation.

Minimal AutoRoute example (route declarations):

@MaterialAutoRouter(
  routes: [
    AutoRoute(page: HomePage, initial: true),
    AutoRoute(page: ProfilePage),
  ],
)
class $AppRouter {}

// After running build_runner you'll use:
// final appRouter = AppRouter();
// appRouter.push(ProfileRoute(userId: '123'));

Best Practices

• Keep navigation logic out of UI widgets: use small navigation services or route helpers to avoid duplicated route strings.
• Use typed arguments when possible: AutoRoute gives you typed route classes; with GoRouter prefer extracting and validating params centrally.
• Centralize authentication redirects: both libraries let you implement a redirect callback — do this in one place to avoid bugs.
• Favor declarative UI: represent the current navigation state with widgets where possible rather than imperative pushes everywhere.
• Write tests for routing: assert that deep links and guarded routes behave as expected.

Pro Tips:

• If your app is web-heavy, start with GoRouter — URL syncing and redirects work naturally.
• If you have a large app with many screens and typed arguments, AutoRoute reduces runtime errors via generated classes.
• For mixed needs, you can use AutoRoute for internal app screens and GoRouter for web-facing URL handling — but do this only if necessary.
• Use small integration tests to validate deep links and authentication flows; routing regressions are subtle and painful.

Examples — Real-world Patterns

Below are two practical examples showing an auth-guarded route for each library.

GoRouter — Auth Redirect Pattern

final goRouter = GoRouter(
  redirect: (context, state) {
    final loggedIn = AuthService.instance.isLoggedIn;
    final loggingIn = state.location == '/login';
    if (!loggedIn && !loggingIn) return '/login';
    if (loggedIn && loggingIn) return '/';
    return null;
  },
  routes: [
    GoRoute(
      path: '/',
      builder: (ctx, st) => HomePage(),
    ),
    GoRoute(
      path: '/login',
      builder: (ctx, st) => LoginPage(),
    ),
  ],
);

// MaterialApp.router(routerConfig: goRouter)

AutoRoute — Route Guard Example

class AuthGuard extends AutoRouteGuard {
  @override
  void onNavigation(NavigationResolver resolver, StackRouter router) {
    if (AuthService.instance.isLoggedIn) {
      resolver.next(true);
    } else {
      router.push(
        LoginRoute(
          onLoginResult: () {
            resolver.next(true);
          },
        ),
      );
    }
  }
}

// In router config: AutoRoute(page: ProfilePage, guards: [AuthGuard])

Conclusion

Both GoRouter and AutoRoute are solid choices. If you prioritize simplicity, web URL-first behavior, and minimal generation, GoRouter is a great default. If your app demands heavy typing, nested routers, and compile-time safety, AutoRoute is the more powerful tool.

My recommendation: start with the simpler approach that fits your app size. If you end up with complex nested flows and brittle string-based navigation, evaluate migrating to AutoRoute. Conversely, if AutoRoute's generated code feels heavy for your team, GoRouter gives you an elegant, less-opinionated path.

FAQ

1. Can I switch from GoRouter to AutoRoute later?

Yes. Migration requires replacing route definitions, moving to generated route classes, and updating navigation calls, but it's doable gradually by feature.

2. Which library is better for deep links and web?

GoRouter has first-class URL synchronization and a design focused on deep links, so it often feels more natural for web-first apps.

3. Is code generation in AutoRoute a maintenance burden?

It adds a build step, but the benefit of strong typing and refactor safety usually outweighs the overhead for large projects.

4. Should I use Navigator 2.0 directly?

Navigator 2.0 gives ultimate control but is verbose. Use it if you need absolute custom behavior; otherwise, GoRouter or AutoRoute handle common cases with far less boilerplate.
