class ResultsPage extends StatefulWidget {
  @override
  _ResultsPageState createState() => _ResultsPageState();
}

class _ResultsPageState extends State<ResultsPage> {
  @override
  Widget build(BuildContext context) {
    return Container(
      margin: EdgeInsets.symmetric(
          vertical: kVerticalMargin, horizontal: kHorizontalMargin),
      child: Column(
        mainAxisAlignment: MainAxisAlignment.center,
        children: <Widget>[
          Text(
            'You are in the top',
            style: kSecondaryTextStyle,
          ),
          Text(
            '23%',
            style: kPrimaryTextStyle,
          ),
          SizedBox(
            height: kSizedBoxHeight,
          ),
          SizedBox(
            width: double.infinity,
            child: RaisedButton(
              onPressed: null,
              child: Text(
                'BACK',
                style: kButtonTextStyle,
              ),
            ),
          ),
        ],
