title: flag.warn()
---

This flags information at the `warn` level.

Info that is flagged is stored in the store under `plugins.plugin-annotations.flags.warn`.
The core library does nothing with this info, it is merely stored, much like logs are.

However, in our own UI on FreeSewing.org, we use this mechanism to allow
designer to flag information to the user, and even suggest changes to the
pattern configuration.

## Signature

```js
undefined Store.flag.warn({
  title: 'Something to be mindful of',
  desc: 'Longer message here'
})
```

Since these methods are not part of FreeSewing's core API, what you pass to this method does depend on your own implementation.
