**here is my Appwrite Services:**

```Future<void> loginWithOAuth(String provider) async {

    } catch (e, s) {
      debugPrint('OAuth login error: $e\n$s');
      throw Exception('OAuth login failed');
    }
  }


OAuthProvider _mapProvider(String name) {

    case 'google':
      return OAuthProvider.google;
    case 'facebook':
      return OAuthProvider.facebook;
    case 'apple':
      return OAuthProvider.apple;
    // add more if you need them
    default:

  }```

    isLoading.value = true;
    try {
      await _appwrite.loginWithOAuth(provider);
      currentUserId.value = await _appwrite.getCurrentUserId();

      print('currentUserId ${currentUserId.value}');
      print("LoginSuccess Controller");
      Get.offAll(() => const App(login: true));
    } catch (e) {
      Get.snackbar('Error', e.toString());
    } finally {
      isLoading.value = false;
    }
  }```

   Future<void> initDeepLinks() async {

    if (appLink != null) {

      var pathName = uri.pathSegments[0];

      if (pathName == 'loginSuccess') {

        Get.to(() => const App(login: true));

  }
