Hi, i am trying to integrate DeepAR in a flutter with [https://pub.dev/packages/deepar\_flutter](https://pub.dev/packages/deepar_flutter). But i am facing some issues with the implementation, as i am not able to build the app itself. I am getting `Undefined symbol` Error.

```auto
Launching lib/main_development.dart on iPhone 13 Pro Max in debug mode...
main_development.dart:1
Xcode build done. 48.1s
Failed to build iOS app
Error (Xcode): Undefined symbol: _OBJC_CLASS_$_ARView

Error (Xcode): Undefined symbol: _OBJC_CLASS_$_CameraController

Error (Xcode): Undefined symbol: _OBJC_CLASS_$_DeepAR

Could not build the application for the simulator.
Error launching application on iPhone 13 Pro Max.

```

I have opened an issue in the [GitHub Here](https://github.com/DeepARSDK/deepar-flutter-plugin/issues/78)

I have updated my findings in the github issue. It builds in physical device, but just keeps showing loading, that is the ar controller is stuck initializing. its not even building for Simulator.  
I am using

- `Xcode Version 14.2 (14C18)`
- `Flutter 3.7.4`
- `deepar_flutter: ^0.0.5`

Hi @jelena is it still being updated? or this already supports Flutter when running on iOS devices
