proposal: lint to flag when an exported API uses types that are not exported #58731
Description
It would be great to have a lint that flags when an exported API uses types that are not themselves exported.
For example:
// library a
class Foo { }// library b
import 'package:a/a.dart';
abstract class Bar {
Foo get foo;
}
// ...Library b should lint that Foo is not exported, correction would be:
// library b
import 'package:a/a.dart';
export 'package:a/a.dart' show Foo; // <--
abstract class Bar {
Foo get foo;
}
// ...
