FlutterAssetsGenerator v2 doesn't have this issue, but in v3 if you add some packages in pubspec.yaml, the plugin will change sources of these packages by adding Assets classes inside each package. But Assets class should be added inside current project only. Maybe It would be more preferable to generate Assets class only inside current project directory and add a way to customize/include/exclude (I don't know what will be more preferable) paths in case when project consists of multiple projects. I hope the problem is clear. Thanks!
