How can I dart pub publish on travis ci deploy

Issue

I would like to know if anyone can provide a nice answer to:

How can I publish a dart package on https://pub.dartlang.org/ during the deploy step, for example on a certain tag or even specified branch?

I have figured that I can run a script as a provider but I assume that the access token is required for pub I guess? Its not super clear so then I decided to ask here. For even more detailed context, my project is here and I would like to tag a release and have it publish like npm release.

Thanks.

Solution

Thanks to the comments I found that the following did solve the issue…

1. Added a section to the .travis.yml to set the deploy script, I changed to branch just for this example since I messed up the tag example

  deploy:
    provider: script
    script: ./tool/publish.sh
    on:
      branch: master

2. Setup some publish.sh that writes the json out

#!/usr/bin/env bash
mkdir -p .pub-cache

cat <<EOF > ~/.pub-cache/credentials.json
{
  "accessToken":"$accessToken",
  "refreshToken":"$refreshToken",
  "tokenEndpoint":"$tokenEndpoint",
  "scopes":["$scopes"],
  "expiration":$expiration
}
EOF

pub publish -f

3. Set the env variables in travis settings for the repo with the show in build disabled.

Only thing now is if it will work after expiry…
