title: Flutter CupertinoButton color always grey
body: <p>Hello I have the following dart code and I want the CupertinoButton to be orange but no matter what I do it stays grey. I have tried changing it to a different color and it still stays grey.</p>
  
  <pre><code>import 'package:flutter/material.dart';
  import 'package:flutter/services.dart';
  import 'package:flutter/cupertino.dart';
  
  void main() =&gt; runApp(new MyApp());
  
  
  class MyApp extends StatelessWidget {
  
    @override
    Widget build(BuildContext context) {
      SystemChrome.setEnabledSystemUIOverlays([]);
  
      return  new MediaQuery(
      data: new MediaQueryData(),
      child: new Container(
        decoration: new BoxDecoration(color: Colors.blue),
        child: new Directionality(
          textDirection: TextDirection.ltr,
          child: new Scaffold(
          body: new Column(
            children: &lt;Widget&gt;[
              new Row(
                mainAxisAlignment: MainAxisAlignment.center,
                children: &lt;Widget&gt;[
                  new CupertinoButton (
                    color: Colors.orange,
                    borderRadius: new BorderRadius.circular(30.0),
                    child:
                    new Text("Get Started",
                      textAlign: TextAlign.center,
                      style: new TextStyle(color: Colors.white),
                    ),
                  )
                ],
              ),
            ],
          )
        )
