Upgrade to React v17 and styled component v5.3

While installing along with React v17 npm install react-flexa
I got the following error:

npm ERR! ERESOLVE unable to resolve dependency tree

It's a great, direct to the point layout solution.
Please update its peer dependencies to the latest versions.
