Solving the Enigma: Flutter Deep Links Not Working with Go Router

Are you tired of scratching your head, wondering why your Flutter app’s deep links are not working with Go Router? You’re not alone! As a developer, you’ve invested countless hours building an exceptional app, only to have users struggle to access specific routes. It’s frustrating, to say the least. But fear not, dear reader, for this article is here to guide you through the treacherous waters of deep linking and Go Router.

The Problem: Flutter Deep Links Not Working with Go Router

Deep linking is a crucial aspect of app development, allowing users to access specific routes within your app. However, when you integrate Go Router, things can get complicated. You’ve set up your routes, but when a user clicks on a deep link, they’re taken to the app’s home screen instead of the intended route. Sounds familiar?

Why Does This Happen?

There are several reasons why your Flutter app’s deep links might not be working with Go Router. The most common culprits are:

• Incorrect route configuration
• Inadequate iOS and Android platform configuration
• Misconfigured Go Router setup
• Inconsistent URL scheme handling

The Solution: Step-by-Step Guide to Fixing Deep Links

Don’t worry, we’ve got you covered! Follow these step-by-step instructions to get your deep links working seamlessly with Go Router:

Step 1: Configure Routes

In your Flutter project, create a new file called `routes.dart`. Define your routes using the `GoRoute` class:

// routes.dart
import 'package:go_router/go_router.dart';

class Routes {
  static final GoRouter _router = GoRouter(
    routes: [
      GoRoute(
        path: '/',
        builder: (_, state) => const HomeScreen(),
      ),
      GoRoute(
        path: '/products/:id',
        builder: (_, state) => ProductScreen(id: state.params['id']!),
      ),
      // Add more routes as needed
    ],
  );

  static GoRouter get router => _router;
}

Step 2: Set Up iOS Platform Configuration

In your `ios/Runner/Info.plist` file, add the following configuration:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>CFBundleURLTypes</key>
    <array>
      <dict>
        <key>CFBundleURLSchemes</key>
        <array>
          <string>your.app.scheme</string>
        </array>
        <key>CFBundleURLName</key>
        <string>your.app.url</string>
      </dict>
    </array>
  </dict>
</plist>

Step 3: Set Up Android Platform Configuration

In your `android/app/src/main/AndroidManifest.xml` file, add the following configuration:

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.your_app">
  <application>
    <activity>
      <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="your.app.scheme" android:host="your.app.host" />
      </intent-filter>
    </activity>
  </application>
</manifest>

Step 4: Configure Go Router

In your `main.dart` file, initialize Go Router with the correct URL scheme:

import 'package:flutter/material.dart';
import 'package:go_router/go_router.dart';
import 'package:your_app/routes.dart';

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  GoRouter.setUrlScheme(PathUrlStrategy('your.app.scheme'));
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp.router(
      routeInformationParser: Routes.router.routeInformationParser,
      routerDelegate: Routes.router.routerDelegate,
      title: 'Your App',
    );
  }
}

Step 5: Handle Deep Links

In your `routes.dart` file, add a `Redirect` class to handle deep links:

class Redirect extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final Uri? uri = Uri.tryParse(Get.arguments.toString());
    if (uri != null) {
      if (uri.host == 'your.app.host') {
        // Handle deep link
        final String? id = uri.pathSegments[1];
        if (id != null) {
          return ProductScreen(id: id);
        }
      }
    }
    return const HomeScreen();
  }
}

Troubleshooting Common Issues

Still having trouble? Don’t worry, we’ve got you covered! Here are some common issues and their solutions:

Issue	Solution
Deep links not opening the app	Check your platform configuration (iOS and Android) and ensure the URL scheme is correctly set.
Go Router not recognizing deep links	Verify that your Go Router setup is correct, and the URL scheme is set correctly in your `main.dart` file.
Deep links not directing to the correct route	Check your route configuration in `routes.dart` and ensure the correct route is defined for the deep link.

Conclusion

And there you have it! With these steps, you should now have deep links working seamlessly with Go Router in your Flutter app. Remember to double-check your platform configuration, Go Router setup, and route definitions to ensure everything is working as expected. If you’re still experiencing issues, refer to the troubleshooting section or seek help from the Flutter and Go Router communities.

Happy coding!
