Flutter packages pub - UnauthorizedAccess: Unauthorized user: ... is not allowed to upload versions to package

Question

I'm trying to publish a new flutter plugin. I followed all the steps to publish my package, my code is uploaded to github: flutter_image_share and everything is ready to be published.

When I run flutter packages pub publish I get this response:

Pub needs your authorization to upload packages on your behalf.
In a web browser, go to https://accounts.google.com/o/oauth2/auth?access_type=offline&approval_prompt=force&response_type=code&client_id=818368855108-8grd2eg9tj9f38os6f1urbcvsq399u8n.apps.googleusercontent.com&redirect_uri=http%3A%2F%2Flocalhost%3A35625&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fuserinfo.email
Then click "Allow access".

I go to the link, I authenticate with my google account and in the end I get this result:

Waiting for your authorization...
Authorization received, processing...
Successfully authorized.
Uploading...
UnauthorizedAccess: Unauthorized user: nadiagnieto@gmail.com is not allowed to upload versions to package flutter_share_image..

After that I run this command: rm ~/.pub-cache/credentials.json to delete the credentials.json and pub uploader add nadiagnieto@gmail.com --verbosity=all to give permissions to this email but I get this response:

FINE: Pub 2.1.0-dev.9.4.flutter-f9ebf21297

I don't know if I am doing something wrong. Does anyone know how can I upload my package? I want to publish two new packages and I am not able to do that.

Answer 1

The message indicated that package already exists.

If you are not the owner, you'll need to chose a different package name.
