failed to install null safety version

[carlhung]

i added the null safety in the yaml.
requests: ^4.0.0-nullsafety.0

but I got this error:
Because note depends on requests ^4.0.0-nullsafety.0 which doesn't match any versions, version solving failed.

The package is not updated on pub.dev yet.

Alternatively you can include the package via git like so:

dependencies:
  requests:
    git:
      url: https://github.com/jossef/requests
      ref: master

[sehnryr]

requests has been updated to 4.1.0 on pub.dev. You can now update your pubspec.yaml with :

dependencies:
  requests: ^4.1.0

I'm closing the issue since it is resolved.
