title: ReactRouter: Pass data/object in <Link>
body: <p>I'm fairly new to React and ReactRouter. I've got basic routing down, and am now trying to pass an object from one component to a sibling component using Link.</p>
  <p>I've spent hours and hours here on SO, and viewing other tutorials, but none of the code I've tried works. I either get an error on the receiving component, or no errors, but then the data I'm supposedly sending is undefined. I have a feeling I'm missing something very basic.</p>
  <p>Can someone either post a very simple working example of sending an object via Link, and using that data in a sibling component? Or, point to an existing working example on StackBlitz or something similar?</p>
  <p>I'm using functional components, React v. 16.13.1, and react-router-dom v. 5.2.0 (version taken from package.json).</p>
  <p>Thanks in advance for any and all help!</p>
