startSDK method

void startSDK({ RequestSuccessListener? onSuccess, RequestErrorListener? onError, })

Initializes the SDK and sets up a method call handler to listen for native callbacks. Guards against multiple initializations with _isSdkStarted

Implementation

void startSDK({
  RequestSuccessListener? onSuccess,
  RequestErrorListener? onError,
}) {
  if (_isSdkStarted) {
    return;
  }
  _isSdkStarted = true;
  if (onSuccess != null || onError != null) {
    _methodChannel.setMethodCallHandler((call) async {
      switch (call.method) {
        case 'onSuccess':
          onSuccess?.call();
          _methodChannel.setMethodCallHandler(null);
          break;
        case 'onError':
          final int errorCode = call.arguments['errorCode'];
          final String errorMessage = call.arguments['errorMessage'];
          onError?.call(errorCode, errorMessage);
          _methodChannel.setMethodCallHandler(null);
          break;
        default:
          print('Unknown method called from the native side.');
          _isSdkStarted = false;
          _methodChannel.setMethodCallHandler(null);
          break;
      }
    });
    _methodChannel.invokeMethod('startSDKwithHandler');
  } else {
    _methodChannel.invokeMethod('startSDK');
  }
}
