Problem with Flow

[AlokBansal8]

When I run yarn test in chapter 02 after adding the Flow. I get following error:

Although when I add following lines in .flowconfig file, the above mentioned error goes away:

[ignore]
<PROJECT_ROOT>/node_modules/eslint-plugin-jsx-a11y/src/rules/media-has-caption.js

But I would like to know if you would recommend it. @verekia
