executeUssdDirect method

@override Future<String?> executeUssdDirect(String ussdCode, int timeoutSeconds, { int? subscriptionId, bool iosFallbackToStandard = false, })

Executes a USSD code directly and gets the response without showing the native system dialog (Android only)

ussdCode - The USSD code to execute timeoutSeconds - Timeout in seconds subscriptionId - (Optional) Subscription ID (SIM slot). If not provided and there are multiple SIMs, the native selector will be shown. If there is only one SIM, it is used by default. iosFallbackToStandard - (iOS only) If true, uses executeUssd as fallback.

Implementation

@override
Future<String?> executeUssdDirect(
  String ussdCode,
  int timeoutSeconds, {
  int? subscriptionId,
  bool iosFallbackToStandard = false,
}) async {
  try {
    final Map<String, dynamic> arguments = {
      'ussdCode': ussdCode,
      'timeoutSeconds': timeoutSeconds,
      'iosFallbackToStandard': iosFallbackToStandard,
    };
    if (subscriptionId != null) {
      arguments['subscriptionId'] = subscriptionId;
    }

    final result = await methodChannel.invokeMethod<String>(
      'executeUssdDirect',
      arguments,
    );
    return result;
  } on PlatformException catch (e) {
    debugPrint('Error executing direct USSD: ${e.message}');
    return null;
  }
}
