title: How to make a card widget touchable in Flutter?
body: <p>I am currently making an app with lists of a <strong>Card</strong> widgets. This is a code snippet:</p>
  <pre><code>new GestureDetector(
          onLongPress: () {
            showAlert(); 
          //pops up an AlertDialog
          },
          child: new Card(child: new Text(&quot;Hello&quot;))
  )
  </code></pre>
  <p>Is it possible to make the Card widget touchable, so <strong>the user can feel/see that the card is (long)tapped?</strong> I am searching for an 'InkWell-something result'.</p>
  <p><em>Edit:</em> I want to have a splash effect on my Card widgets when I longpress them.
  An example of the splash effect that I mean is given in the following GIF:</p>
