title: listview ripple effect in flutter
body: <p>i have a simple listview in flutter</p>
  
  <pre><code>final List&lt;String&gt; entries = &lt;String&gt;['A', 'B', 'C'];
  final List&lt;int&gt; colorCodes = &lt;int&gt;[600, 500, 100];
  
  ListView.builder(
    padding: const EdgeInsets.all(8),
    itemCount: entries.length,
    itemBuilder: (BuildContext context, int index) {
      return Container(
        height: 50,
        color: Colors.amber[colorCodes[index]],
        child: Center(child: Text('Entry ${entries[index]}')),
      );
    }
  );
  </code></pre>
  
  <p>when i click/tap on it, there is a circle ripple effect that then expand to the rest of the element i clicked in the list.  i would like to change this behavior and remove the circle ripple effect. instead when someone click on an element of the list, i want that element to highlight and fade away for the whole element.  one examples is whatsapp app. when you click on a conversation, you will see that the element you click in the list will flash with ripple effect of the full element.  you will see a rectangle ripple effect not a circle ripple effect where you click and then expands to the rest of the element</p>
  
  <p>how can i change the default behavior on listview in flutter?  if im not clear, let me know
  thanks in advance</p>
