Implementation

String createSecureRedirectUrl(String fi, String reqdate, String ecreq, {String? theme}) {
  // Use the current environment's URL
  final String baseUrl = SaafeSdk.baseRedirectUrl;
  final Uri url = Uri.parse(baseUrl);

  // Add the required query parameters, only if they're not empty
  final Map<String, String> queryParams = {};

  if (fi.isNotEmpty) queryParams['fi'] = fi;
  if (reqdate.isNotEmpty) queryParams['reqdate'] = reqdate;
  if (ecreq.isNotEmpty) queryParams['ecreq'] = ecreq;

  // Add platform flag
  if (Platform.isIOS) {
    queryParams['platform'] = 'ios';
  } else if (Platform.isAndroid) {
    queryParams['platform'] = 'android';
  } else {
    queryParams['platform'] = 'flutter';
  }

  // Add theme flag if provided, otherwise use system
  if (theme != null && (theme == 'light' || theme == 'dark')) {
    queryParams['theme'] = theme;
  } else {
    // Get system theme
    final Brightness systemBrightness = WidgetsBinding.instance.platformDispatcher.platformBrightness;
    queryParams['theme'] = systemBrightness == Brightness.dark ? 'dark' : 'light';
  }

  // Log if parameters are empty
  if (queryParams.isEmpty || (fi.isEmpty || reqdate.isEmpty || ecreq.isEmpty)) {
    debugPrint("SAAFE SDK Warning: Some or all parameters are empty. This will result in an incomplete URL.");
  }

  final String finalUrl = url.replace(queryParameters: queryParams).toString();
  return finalUrl;
