arch_guard_lint

Shows arch_guard rules as warnings on the offending import line, in VS Code, Android Studio / IntelliJ and dart analyze / flutter analyze.

Warning	When
layer_violation	An import crosses a layer boundary that allowed_imports does not allow.
forbidden_package	An import uses a package or core library listed under forbidden_packages.

Install

Requires Dart 3.10 / Flutter 3.38 or later.

# analysis_options.yaml
plugins:
  arch_guard_lint: ^0.1.0

Restart the Dart analysis server afterwards (in VS Code: Dart: Restart Analysis Server).

How it works

• Rules come from the same arch_guard.yaml (or pubspec.yaml arch_guard: section) the CLI uses. The plugin looks for arch_guard.yaml in the package and its parent folders, so a workspace-root config works too.
• Only files under lib/ are checked, minus the config's ignore: globs.
• Problems already in arch_guard_baseline.json are not shown, so enabling the plugin on an existing codebase doesn't fail dart analyze.
• Edits to arch_guard.yaml or the baseline take effect without a restart.

Suppress a single warning:

// ignore: arch_guard_lint/layer_violation
import '../data/repo.dart';

Circular dependencies need the whole project graph, so they are not checked in the IDE. Use the arch_guard CLI or expectArchitecture() from package:arch_guard/testing.dart for those.
