Flutter——实现闪烁效果（flutter弹出框）

我们在加载列表的时候，数据没请求下来之前，一般会有个加载对话框的交互，也有闪烁骨架屏交互，下面我们在flutter中实现闪烁骨架屏的交互。

1,添加依赖

shimmer: ^1.0.0
复制代码

2，获取依赖包

flutter pub get
复制代码

3，导入需要使用的文件中

import 'package:shimmer/shimmer.dart';
复制代码

4,使用

class MyShimmer extends StatelessWidget {
 @override
 Widget build(BuildContext context) {
 return SizedBox(
 child: Shimmer.fromColors(
 baseColor: Colors.grey,
 highlightColor: Colors.white,
 child: Column(
 children: <Widget>[
 CoinRankingListItemSkeleton(),
 CoinRankingListItemSkeleton(),
 CoinRankingListItemSkeleton(),
 CoinRankingListItemSkeleton(),
 CoinRankingListItemSkeleton(),
 CoinRankingListItemSkeleton(),
 ],
 ),
 ),
 );
 }
}
class CoinRankingListItemSkeleton extends StatelessWidget {
 @override
 Widget build(BuildContext context) {
 return Container(
 margin: EdgeInsets.fromLTRB(10, 5, 10, 5),
 height: 80.0,
 child: Row(
 children: <Widget>[
 Container(width: 100.0, height: 100.0, color: Colors.grey),

 Container(width:20.0,height: 10.0, color: Colors.grey),
 ],
 )
