Best way to implement deep linking in a Flutter app without GoRoute using a custom URL

I am working on a Flutter app and would like to implement deep linking using custom URLs. However, I do not want to use the go_router package and prefer handling deep linking manually. What is the best method or approach to implement deep linking in a Flutter app with custom URL without relying on GoRoute?

Any suggestions or code examples would be highly appreciated.

    You’re on the right track wanting to handle deep linking manually—it gives you a lot of flexibility! For implementing deep linking in Flutter without using the go_router package, you can make use of Navigator 2.0 combined with Uri parsing. The key steps are:

    Set up the initial route handling by overriding the onGenerateRoute or using onGenerateInitialRoutes.
    Use onGenerateRoute or onUnknownRoute to catch custom URL schemes and map them to your app’s routes.
    Implement a RouteInformationParser to parse incoming URLs into a data structure your app can handle.

    You can use the following library app_links.

    To start with, you need to follow docs to configure Android / iOS and more here.

    After, you just need to instanciate the plugin and subscribe to events like this:

    final appLinks = AppLinks();

final sub = appLinks.uriLinkStream.listen((uri) {
    if (uri.path == 'your/path') {
      Navigator.pushNamed(
        globalNavigatorKey.currentContext!,
        '/your/flutter/page',
    );
    }
});

    For the globalNavigatorKey, you can assign it to your MaterialApp widget widget like this:

    final GlobalKey<NavigatorState> globalNavigatorKey =
    GlobalKey<NavigatorState>();

// [...]

MaterialApp(
  navigatorKey: globalNavigatorKey,
  // ...
);
