  <p>I wan't to get the outline border of two containers in a Stack, one positioned like the image suggest. My goal is to remove the &quot;red&quot; part.</p>
  <p>How can I accomplish this in Flutter?</p>
  <pre class="lang-dart prettyprint-override"><code>Widget build(BuildContext context) {
      return Stack(
        overflow: Overflow.visible,
        children: [
          Container(
            width: 200,
            height: 200,
            decoration: BoxDecoration(
              border: Border.all(),
            ),
            child: const Center(child: Text(&quot;BLABLABLA&quot;)),
          ),
          Positioned(
            top: -10,
            left: 10,
            child: Container(
              width: 150,
              height: 25,
              decoration: BoxDecoration(
                border: Border.all(),
              ),
              child: const Center(child: Text(&quot;BLABLABL2&quot;)),
            ),
          ),
        ],
      );
    }
  </code></pre>
