title: Flutter - Smooth transition color for LinearGradient
body: <p>Hellow!</p>
  
  <p>Is there a solution for creating a LinearGradient that has a smooth transition between start and ens color?</p>
  
  <pre><code>new Container(
          decoration: new BoxDecoration(
            gradient: new LinearGradient(
                colors: [
                  Colors.black,
                  Colors.grey,
                ],
              stops: [0.0, 1.0],
              begin: FractionalOffset.topCenter,
              end: FractionalOffset.bottomCenter,
              tileMode: TileMode.repeated
            )
          ),
  )
  </code></pre>
