Hello @Aljullu
Thank you for your comments.

I added PropTypes and defaultProps in Alphabet order.
If I made a mistake, please tell me.

Thank you for your changes @partykyoung!

I'm not sure, however, how the last commit you added is related to the props changed in the first commit. If they are not related, it would be better to split the changes in different PR. How does it sound?

Ok! I will do this :)

  ● Test suite failed to run
    SecurityError: localStorage is not available for opaque origins
      
      at Window.get localStorage [as localStorage] (node_modules/jsdom/lib/jsdom/browser/Window.js:257:15)
      at Array.forEach (native)

I saw this error message, So I looked for a way to fix this error and found this link and added testUrl to package.json. I'm sorry I did not write a comment.
