How can I pass parameters in deeplink flutter?

Question

I have setup deeplinking on my flutter application but I'm having trouble in being able to pass and use a parameter. Normally, the deeplink works for a predefined named route, say I press a link https://domain/signup - this will redirect the user to the signup page on my Flutter app. But the issue here is, I'm not able to pass a parameter so that I can make my page more dynamic - say a user presses on a link https://domain/course/:some-id - I want to redirect the user to that specific course page. I believe I have setup the deeplink correctly - well at least to what I have seen from the flutter docs. I'm using named route and I know it says using router is a preferred way to Here is my AndroidXML file setup

<!-- Deep Links -->
<meta-data
                android:name="flutter_deeplinking_enabled"
                android:value="true"
            />
            <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="scheme"
                    android:host="domain" />
            </intent-filter>

            <!-- App Links -->
            <intent-filter android:autoVerify="true">
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
                <data
                android:scheme="https"
                android:host="domain.com" />
                <data
                android:scheme="http" />
            </intent-filter>

I have made a custom deeplink handler - and its not working how I wanted it to


class DeepLinkHandler {
  static Future<void> initUniLinks(BuildContext context) async {
    try {
      // Get the initial deep link
      final initialLink = await getInitialLink();

      // Handle the initial deep link if it exists
      _handleLink(initialLink, context);

      // Listen for incoming deep links
      linkStream.listen((String? link) {
        _handleLink(link, context);
      }, onError: (error) {});
    } catch (error) {
      throw Exception();
    }
  }

  static void _handleLink(String? link, BuildContext context) {
    if (link != null) {
      final Uri deepLink = Uri.parse(link);

      print('deeplink opened was $deepLink');
      // This is where I want to navigate the user to the right page
    }
  }

  static Future<void> openLink(String link) async {
    if (await canLaunchUrl(Uri.parse(link))) {
      await launchUrl(Uri.parse(link));
    }
  }
}

How can I route to a specific pages with a certain parameter attached to it.
