Used the example code mentioned in https://pub.dartlang.org/packages/arcore_flutter_plugin#example

Getting the following error message in the console while running the app:

hi, did you try other native application with ARCore ?
Do you have ARCore installed in you device?
I will check installation process of ARCore of my plugin...

[yash365]

I don't have arcore install in my device... how can I download it ?

[giandifra]

@giandifra
I had the same issue but I was unable to install arcore. It says that my device isn't compatible. However, my device is arm-64 with Android 9 and API 28. What is the issue!?
