isFromExpectedPackage function

bool isFromExpectedPackage(NamedType namedType, String expectedPackage)

Returns true if namedType originates from expectedPackage.

If the type can't be resolved (e.g. unresolved import), returns true to avoid false negatives — the rule should still fire rather than silently skipping a real issue just because the type didn't resolve.

Implementation

bool isFromExpectedPackage(NamedType namedType, String expectedPackage) {
  final type = namedType.type;
  if (type == null || type is! InterfaceType) return true;
  final uri = Uri.tryParse(type.element.library.identifier);
  if (uri != null && uri.scheme == 'package') {
    return uri.pathSegments.firstOrNull == expectedPackage;
  }
  return true;
}
