I have a flutter project using retrofit that was working fine.

I decided to move my freezed models and retrofit files to a separate project in order to be reused with another project. I updated my imports and pubspec.yaml to properly include the new project and receive no errors in VSCODE.

When I goto to build my project, I am receiving the following on all my retorfit .g generated files:

../gtp-flutter-data/lib/data/providers/cart_api_service.g.dart:24:9:
Error: Type 'ParseErrorLogger' not found.
  final ParseErrorLogger? errorLogger;

I have no errors in either the new or the main data project, but this appears when building.

Any suggestions on what is going on?

It might happen for some reason, so do try all steps:

1. Check and verify that ParseErrorLogger is correctly defined and accessible in your new shared project.

2. Try rebuilding the generated files:

   flutter pub run build_runner clean

   flutter pub run build_runner build --delete-conflicting-outputs

   in both the main project and the shared data project.

3. Ensure that the shared project includes all necessary dependencies (retrofit, freezed, json_serializable, etc.) in your pubspec.yaml file.

4. Confirm that ParseErrorLogger is imported where you are using it.

I finally figured it out, albeit I’m not sure why what I did worked. I ended up solving this by temporarily commenting out retrofit in the main project pubspec.yaml and building the project.

After this build it did not matter whether retrofit was included or commented out anymore in the pubspec.yaml of the main project.

you can try

import 'package:retrofit/retrofit.dart' instead of import 'package:retrofit/http.dart';
