Flutter – Deep Link Not Working on Devices – Link Opens in Browser Instead of App

I am trying to implement deep linking in my Flutter app without using Firebase Dynamic Links. I have followed the necessary steps to enable app links using Android App Links. However, when I try to open the deep link on some Android devices, particularly on Samsung devices, the link opens in the browser (Chrome) instead of launching the app.

AndroidManifest.xml

 <meta-data android:name="flutter_deeplinking_enabled" android:value="true" />

            <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="apartment.sakany.app"
                />
            </intent-filter>

I am using the app_links Flutter package to handle deep links:

DeepLinkService Class
I am using the app_links Flutter package to handle deep links:

class DeepLinkService {
  static const String domainUrl = 'https://apartment.sakany.app';
  static Future generateDynamicLink({
    required String urlParams,
    bool withShare = true,
  }) async {
    try {
      final shortUrl = Uri.parse("$domainUrl$urlParams");
      if (withShare) {
        shareLink(shortUrl);
      } else {
        await FlutterClipboard.copy(shortUrl.toString());
        return shortUrl;
      }
    } catch (e) {
      print(e.toString());
    }
  }

  static shareLink(Uri link) async {
    await Share.share(link.toString());
  }
}

AppLinksService Class
I handle deep link navigation with the following code:

class AppLinksService {
  static String _code = '';
  static String get code => _code;
  static bool get hasCode => _code.isNotEmpty;

  static void resetCode() => _code = '';

  static final AppLinks _appLinks = AppLinks();
  static Uri? _lastProcessedLink;
  static bool fromDeepLink = false;

  static init() async {
    try {
      final Uri? initialLink = await _appLinks.getInitialLink();
      if (initialLink != null) {
        handleDeepLink(initialLink);
      }
    } catch (e) {
      print('Error handling initial app link: $e');
    }

    _appLinks.uriLinkStream.listen((Uri? link) {
      if (link != null) {
        handleDeepLink(link);
      }
    }, onError: (Object err) {
      print('Error handling app link: $err');
    });
  }

  static void handleDeepLink(Uri? link) {
    if (link != null && link != _lastProcessedLink) {
      fromDeepLink = true; // Mark the navigation as triggered by a deep link
      _lastProcessedLink = link;
      print('Received link: $link');
      WidgetsBinding.instance.addPostFrameCallback((_) async {
        Map<String, String> params = link.queryParameters;
        String receivedId = params['id'] ?? '';

        if (receivedId.isNotEmpty) {
          print('Received id: $receivedId');
          NavigationService.navigateTo(AppRouter.kAppartmentDetailsScreen, extra: receivedId).then((_) {
            fromDeepLink = false;
          });
        } else {
          print("No valid ID found in the deep link.");
        }
      });
    }
  }

  static void clearLastProcessedLink() {
    _lastProcessedLink = null;
  }
}

1.Why are app links not opening the app on devices?

How can I ensure the link automatically opens the app instead of the browser across all devices?
