Freezed - cannot find my type after file rename

Question

I just renamed a bunch of files and now I can't start my app as it has all these run-time errors to the effect of:

VpUser? createdBy,
            ^^^^^^
: Error: 'VpUser' isn't a type.

Then I go to my code where the error is supposed to be and the error doesn't exist at all. I can right-click > go to definition from the freezed file and it goes to the class. No reported problems in my vs code. Why does my app not compile when the errors in the debug console do not appear to exist?

The example error above is for this code:

user.dart:

import 'package:firebase_auth/firebase_auth.dart';
import 'package:freezed_annotation/freezed_annotation.dart';

import '../../_common/entity_types/domain_entity.dart';
import '../../_common/utils/string_utils.dart';
import '../../application/local/image_picker_image/image_picker_image.dart';
import 'user_dto.dart';

part 'user.freezed.dart';
part 'user.g.dart';

/// This is the user of the application.

    if (dto.profilePicture != null) {
      final position = dto.profilePicture!.lastIndexOf('/') + 1;
      final fileName =

    }

    final entity = VpUser(

Answer 1

Some of my imports had "//" where there should be obviously "/", E.G:

import '../_common//local_repo.dart';

for some reason this does not cause any problems for vscode and is a completely hidden error, and you can right-click > go to definition still when the import has "//" but the app does not compile. Probably worth keeping this online as it is pretty unexpected.
