Set `useRootAsPackage: true` in the package `pubspec.yaml` file. No workspace list is required.

```yaml
name: my_single_package
environment:
  sdk: ^3.9.0

dev_dependencies:
  melos: ^8.0.0

melos:
  useRootAsPackage: true
```

Applications are usually private (`publish_to: none`), and `melos version` skips
private packages by default. To version an application, you also need
to pass `--all` to `melos version`, or set
[`versionPrivatePackages: true`](/configuration/overview#versionprivatepackages):

```yaml
name: my_application
publish_to: none
environment:
  sdk: ^3.9.0

dev_dependencies:
  melos: ^8.0.0

melos:
  useRootAsPackage: true
  command:
    version:
      versionPrivatePackages: true
```

The build number of the version of an application is retained and incremented
when it is versioned, so `1.2.3+45` becomes `1.3.0+46`, see
[Build numbers](/guides/automated-releases#build-numbers).
