一、创建package或plugin

先创建一个package或者plugin

二、手动上传第一个版本到pub.dev

flutter packages pub publish --server=https://pub.dartlang.org

三、在admin配置自动化发布

打开pub.dev中的对应的package按照以下图片配置

四、在项目跟目录配置发布脚本

1、在项目根目录创建 .github/workflows/publish.yml文件
2、文件脚本如下：

name: Publish to Pub.dev

# 流程触发时机，create当有标签tag创建时触发，如 v1.0.0。当然也可以选择别的触发时机，如 push，release 等
on: create
#  push:
#    branches:
#      - master

jobs:
  publishing:
    runs-on: ubuntu-latest
    steps:
      # 拉取仓库代码
      - name: "Checkout"
        uses: actions/checkout@v3
      # 发布插件
      - name: Dart and Flutter Package Publisher
        uses: k-paxian/dart-package-publisher@master
        with:
          accessToken: ${{ secrets.OAUTH_ACCESS_TOKEN }}
          refreshToken: ${{ secrets.OAUTH_REFRESH_TOKEN }}
          suppressBuildRunner: true
          flutter: true
          skipTests: true
          force: true

k-paxian/dart-package-publisher的参数请看GitHub：dart-package-publisher

五、在github的项目设置中设置token

1、打开github中对应项目的setting


2、分别添加token:OAUTH_ACCESS_TOKEN和OAUTH_REFRESH_TOKEN
在文件目录找到pub-credentials复制这两个token
On Mac OS:

~/Library/Application Support/dart/pub-credentials.json

On Windows:

%APPDATA%/dart/pub-credentials.json

六、测试

1、提交代码或者创建tag测试CI脚本执行是否发布成功

git tag v0.4.0
git push --tags

七、报错

解决办法：脚本中with需要设置参数：force: true
