title: Box constraints not respecting minWidth and minHeight
body: <p>My container width and height size defaults to the minWidth and maxWidth property set in the BoxConstraints which is contrary to the result I want. It should grow from the minWidth then hit the maxWdith and stop growing. Code below.</p>
  
  <pre><code>Container(
