title: Flutter overflow: hidden analogue
body: <p>Is there any flutter widget that prevents the children to paint outside a Container by any mean?</p>
  
  <p>I have this container with a child that may get some transformations (such as scale and rotate) and therefore can be painted outside </p>
  
  <p>I want to limit the children's painting to only inside the parent Container, just like a div with CSS <code>overflow:hidden;</code> would behave.</p>
  
  <p>A sample:</p>
  
  <pre><code>return Container( // the one with overflow hidden -ish behavior
     height: 300.0,
     child: TheTransformingChild() // the one that can get bigger that container
  )
  </code></pre>
