[docs] Docs are not being generated for Hidden

Imported PropTypes not working with react-docgen

I am encountering an error when running the npm script to build docs:

Error generating markdown for Hidden
TypeError: Cannot read property 'name' of undefined
    at generatePropDescription (/material-ui/scripts/generate-docs-markdown.js:32:7)
    at /material-ui/scripts/generate-docs-markdown.js:144:25
    at Array.reduce (native)
    at generateProps (/material-ui/scripts/generate-docs-markdown.js:142:29)
    at generateMarkdown (/material-ui/scripts/generate-docs-markdown.js:198:8)
    at /material-ui/scripts/build-api-docs.js:60:18
    at tryToString (fs.js:456:3)
    at FSReqWrap.readFileAfterClose [as oncomplete] (fs.js:443:12)

This is happening because react-docgen is not providing required, description, flowType, or type for any of the props defined in src/Hidden/types.js:

• xsUp: { defaultValue: { value: 'false', computed: false } }
• smUp: { defaultValue: { value: 'false', computed: false } }
• mdUp: { defaultValue: { value: 'false', computed: false } }
• lgUp: { defaultValue: { value: 'false', computed: false } }
• xlUp: { defaultValue: { value: 'false', computed: false } }
• xsDown: { defaultValue: { value: 'false', computed: false } }
• smDown: { defaultValue: { value: 'false', computed: false } }
• mdDown: { defaultValue: { value: 'false', computed: false } }
• lgDown: { defaultValue: { value: 'false', computed: false } }
• xlDown: { defaultValue: { value: 'false', computed: false } }

It looks like the last time Hidden.md was built was with this commit, but it should have been built when @oliviertassinari updated the docs with PR #6892.

Also, the type listed on Grid for the Hidden property is HiddenProps, which may benefit from more of an explanation. Maybe a link to the Grid/Hidden demos would be sufficient.

Versions

• Material-UI: 1.0.0-alpha.15

react-docgen has an open issue for imported propTypes (I see you in the comments, @oliviertassinari! 👋)

Closing for #6818.

Regarding that point. I agree, to you want to submit a PR? :)
