      print('Msal exception with error: ${e.errorMessage}');
    } catch (e) {
      print(e.toString());
    }
  }

anyone faced the same problem ?

i found out that this library doesnt work for "SINGLE" accounts_mode, this code is executed either your specify single or multiple, i would be awesome if we can implement for single account

        PublicClientApplication.createMultipleAccountPublicClientApplication(
            msal.applicationContext,
            File(configFilePath!!),
            msal.getApplicationCreatedListener(result)
        )
