title: How do I add dynamically widgets to a subtitle? (for ListTile)
body: <p>I'm trying to add Chips to the ListTile subtitle, so that when the listTile is created via a ListView.builder, depending on the user's selection, they can have or see multiple chips in the subtitle.</p>
  
  <pre><code>ListView.builder(
  
        scrollDirection: Axis.vertical,
        itemCount: myShoppingBasketList.length,
        itemBuilder: (ct, shoppingListViewBuilderItemInteger)
        {
  
         return Card(
              child: ListTile(key: UniqueKey(),
                  //dense: true,
                  leading: ...,
                  title: ...
                  subtitle: Wrap(&lt;add chips here)...
                  onTap: () 
                  {
  
  // Code to add new chips depending on selection
  
  
                  }
  
          })
  </code></pre>
  
  <p>So - how could I dynamically += add to a Wrap widget. When I say</p>
  
  <pre><code>+=
  </code></pre>
  
  <p>What I'm hoping for is that if a Chip was like a String, then I'd like something like:</p>
  
  <pre><code>Wrap(SomeChipContainerWidget = SomeChipContainerWidget+ newChipWidget))
  </code></pre>
  
  <p>Do you see my problem??</p>
  
  <p>So let's say the subTitle was a Text widget, then the String text inside could be:</p>
  
  <p>Text(stringVar += stringVar + newString)</p>
  
  <p>I have tried EVERYTHING - You cannot imagine. I've looked at Expansion Tiles - does't work, Animated, etc..</p>
  
  <p>Any help will be really appreciated. Even sympathy.</p>
