title: Flutter Container Positioning or alignment inside Row widget
body: <p>I'm new in flutter. right now learning how to positioning or aligning widgets. I have two containers inside my row widget. I want to set my first container(which is red container) at the top left, and also want to set my second container(which is blue container) at the top right. how can I achieve this?</p>
  
  <p>here is code sample :</p>
  
  <pre><code>class MyRow extends StatelessWidget {
    @override
    Widget build(BuildContext context) {
      return MaterialApp(
        home: Scaffold(
          backgroundColor: Colors.teal,
          body: SafeArea(
            child: Row(
              children: &lt;Widget&gt;[
                Container(
                  width: 100.0,
                  height: 100.0,
                  color: Colors.red,
                ),
                Container(
                  width: 100.0,
                  height: 100.0,
                  color: Colors.blue,
                ),
              ],
            ),
          ),
        ),
      );
    }
  }
  </code></pre>
