Error after used pub upgrade and the error show RC2Parameters that never heard.

This issue has been tracked since 2023-03-17.

After I used pub upgrade I got this error and I don't know why. Although I comment on the crypto package(I see the crypto is a path in the error) this error still appears.

Launching lib\main.dart on Chrome in debug mode...
Waiting for connection from debug service on Chrome...
/C:/Users/user/AppData/Local/Pub/Cache/hosted/pub.dev/basic_utils-5.5.1/lib/src/library/crypto/rc2_engine.dart:4:1: Error: 'RC2Parameters' is imported from both 'package:basic_utils/src/library/crypto/rc2_parameters.dart' and 'package:pointycastle/api.dart'.
import 'package:pointycastle/export.dart';
^^^^^^^^^^^^^
Failed to compile the application.

I tried to ctrl+shift+f to find package:basic_utils/src/library/crypto/rc2_parameters.dart and RC2Parameters but this is not found.

This error is coming from the basic_utils package; you'll need to report it to the developers of that package. It looks like they'll need to update it for a conflict in its dependencies.

What worked for me is is that

for the import - import 'package:basic_utils/src/library/crypto/rc2_parameters.dart'

I added as crypto so It wouldn't be ambiguous.

Editing files in your pub cache is not recommended, as the cache is subject to being cleared or rebuilt.

No current workaround besides editing pub cache?

I am not using the basic_utils package why do I face this error?
Or this package was required in some package that I am using?

I tried to find the package that makes this error, and the result is the mongo_dart package. When I import this package I will receive this error and the app can work when I don't import this package.

The packages I am using are:

  cupertino_icons: ^1.0.2
  flutter_lints: ^2.0.0
  collection:
  intl: ^0.17.0
  image: ^4.0.15
  universal_html: ^2.0.8
  google_fonts: ^3.0.1
  get: ^4.6.5
  mongo_dart: ^0.9.1
  url_strategy: ^0.2.0
  flutter_easyloading: ^3.0.5
  font_awesome_flutter: ^10.3.0
  shared_preferences: ^2.0.17
  syncfusion_flutter_datagrid: ^20.4.52
  dart_jsonwebtoken: ^2.6.1

I tried to import all these packages and an error will happen when importing the mongo_dart.

I tried this and the build was successful

please remove ^ in the basic_utils: ^5.3.0 and do basic_utils: 5.3.0 this is currently working

Please post any further discussion in Ephenodrom/Dart-Basic-Utils#84 rather than in this closed issue.

I am not using the basic_utils package why do I face this error?

Yes, anyone with this error has a dependency on basic_utils, either direct or transitive.

I'm with the same problem, can't compile and using only this dependencies:

dart_frog: ^0.3.4
mongo_dart: ^0.9.1

Look this issue: mongo-dart/mongo_dart#327

You can override the package
dependency_overrides: basic_utils: "5.3.0"
