  Widget build(BuildContext context) {
    return SizedBox(
      child: Shimmer.fromColors(
        baseColor: Colors.grey,
        highlightColor: Colors.white,
        child: Column(
          children: <Widget>[
            CoinRankingListItemSkeleton(),
            CoinRankingListItemSkeleton(),
            CoinRankingListItemSkeleton(),
            CoinRankingListItemSkeleton(),

}

class CoinRankingListItemSkeleton extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
