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

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 libmain.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.

    The basic_utils is the cause of this issue.

    This error happened when importing any package that has a dependency on basic_utils, either direct or transitive as mentioned in github.

    For me, this package that uses the basic_utils is the mongo_dart.

    The solution that can fix this issue before the maintainer of the basic_utils package fixes this is to override the dependency by adding the following lines in the pubspec.yaml as mentioned in github:

    dependency_overrides:
  basic_utils: 5.4.2

  2. 0

    You can override the package

    dependency_overrides:
  basic_utils: "5.3.0"
