I get errors in console when I try to run the app on android emulator

Hi when I try to run my app with the package I get this error

I run the exact code you have provided in the pub.dev https://pub.dev/packages/flutter_web_gl/example

While I'm not a developer of this library, I'm noticing you have ffi-0.2.0 while the repo has ffi: ^1.0.0 in its pubspec.
Might it be that you are somehow using an older version of the library?
Maybe try explicitly pointing to the github repo in the example's pubspec:

  flutter_web_gl:
    git: https://github.com/FlutterGL/flutter_web_gl/

The example does compile on my machine, but I'm encountering emulator runtime issues: #13
