There was an internal request to update the typescript types too. cc @lunaleaps

[lunaleaps]

Hi @ankit-tailor! As Nicolas mentioned can we update the TS types here:

react-native/Libraries/Components/View/ViewPropTypes.js

Line 534 in 4363626

'aria-checked'?: ?boolean,

and other related places if any

[ankit-tailor]

Yes @lunaleaps, I'll do the necessary changes.

[ankit-tailor]

@lunaleaps, Only ViewAccessibility props required the above changes, other than that everywhere else ViewAccessibility props are extended.
