UnityWidget crashing upon loading using flutter_unity_widget

Ive created a simple flutter program to test out the plugin on flutter. ive set up a simple unity project with a button and imported it using the plugin to the flutter project. everything builds up correctly and my app runs, however the app crashes upon loading the UnityWidget

To Reproduce Steps to reproduce the behavior: create simple app in unity and flutter exported unity as per instructions on Readme moved unityLibrary from 'project Root/unity/android' to 'project Root/android' in order to fix unityLibrary not found build error

UnityWidgetController? overallController;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Second Route'),
      ),
      body: SafeArea(
        top: true,
        bottom: true,
        child: Stack(
          children: [
            UnityWidget(
              onUnityCreated: onUnityCreate,
              borderRadius: BorderRadius.zero,
            ),
          ],
        ),
      ),
    );
  }

  void onUnityCreate(UnityWidgetController controller) {
    overallController = controller;
    controller.postMessage("ButtonManager", "setFromFlutter", "message");
  }
