Cannot build example

[nebis-software]

Describe the bug I would like to test this library, and I started with cloning the repo and building the example. I get errors (see below) It seems to me as related to an older gradle version, but I don't know how to proceed... Thanks!

To Reproduce Steps to reproduce the behavior:

git clone git@github.com:juicycleff/flutter-unity-view-widget.git
cd flutter-unity-view-widget.git/example
dart pub get
flutter run -v

Hi @nebis-software you need to install Unity and perform export first
