Hi there! thanks for the PR. I think right now withState is deprecated so can we update the doc to use useState instead?

I will approve and merge changes since there has been no activity for some time, and the changes are correct.

I started working on replacing withState with the useState hook. The first part can be found here #33173. I will handle additional changes requested in the upcoming PR.
