Resolving dependencies... Because three_dart depends on flutter_gl from path which doesn't exist (could not find package flutter_gl at "..\flutter_gl\flutter_gl"), version solving failed. pub get failed command: "E:\flutter\bin\cache\dart-sdk\bin\dart __deprecated_pub --directory . get --example" pub env: { "FLUTTER_ROOT": "E:\flutter", "PUB_ENVIRONMENT": "flutter_cli:get", "PUB_CACHE": "C:\Users\Anonymous\AppData\Local\Pub\Cache", } exit code: 66

Hi Alilmrangang, Looks like you might be using a downloaded version rather than the pub dev version. You need to go into the three_dart pubspec.yaml file and comment out the dependency_overrides or download flutter_gl and place it in the same folder as three_dart.
