depend-on-referenced-packages (depend_on_referenced_packages): Dart lint rule

Cross-file rule. It runs in falcon's whole-project pass, analyzing relationships across every file rather than one file at a time. Configure it under the top-level cross-file key.

Require imported packages to be declared in pubspec.yaml.

Imports from lib/ and bin/ must name a regular dependency. Imports from development-only locations such as test/ and tool/ may also name a dev-dependency. SDK imports and imports of the package itself are ignored. Like the analyzer, only the primary URI is checked, not conditional alternatives. When undeclared-dependencies is enabled for a file, that rule owns missing declarations and dev-dependencies imported from lib/; this rule only adds its stricter executable/build-hook dependency check, avoiding duplicate reports.

Configure depend-on-referenced-packages

Set its severity in falcon.json under the cross-file section. See the configuration guide.

falcon.jsonjson

{
  "cross-file": {
    "rules": {
      "correctness": {
        "depend-on-referenced-packages": "error"
      }
    }
  }
}

Or silence one occurrence with a suppression comment; the reason is required.
