Screenreader-only text

[unindented]

Is your feature request related to a problem? Please describe.
I want my app to have a nice table of contents for screenreaders, but not all headings should be visible to sighted users (e.g. navigation sections).

Describe a solution you'd like
People use variations of this technique on web: https://github.com/twbs/bootstrap/blob/38ca58bf3c886d99e75e307dd6f631a2c9e2c7a2/scss/mixins/_screen-reader.scss#L6-L15

Describe alternatives you've considered
I'd like to hear from @necolas what's the most RNW way of doing this.

[necolas]

The way to do this is the "web way" at the moment. I've mentioned this use case in a RN accessibility proposal to find out how native does the equivalent react-native-community/discussions-and-proposals#56

[necolas]

This is something that should be handled in user-space for now. I won't be adding an API to this library as it won't have any compatibility with React Native
