It addresses Dart's simple visibility model (private in file, public otherwise) by blocking unwanted imports at the IDE and analyzer level. The plugin supports use cases like maintaining layered architectures, enforcing design system usage, preventing IO in unit tests, and controlling module APIs through aggregate files. Configuration lives in analysis_options.yaml with glob patterns defining which files can't import what, showing violations as lint errors without extra CI steps. ## Full article daily.dev links to this article rather than hosting it.
