What's your distribute_options.yaml?

it's exists but empty, i have no plans distribute anything, want to create 'dmg' file only

You need to create a job to package dmg, and also need to create make_config.yamlhttps://distributor.leanflutter.dev/makers/dmg/

output: dist/
releases:
  - name: dev
    jobs:
      - name: release-dmg
        package:
          platform: macos
          target: dmg
          build_args:
            dart-define:
              APP_ENV: dev
