I tried to implement shimmer effect in flutter web using plug in https://pub.dev/packages/shimmer.
But it is throwing following error.
The following UnimplementedError was thrown during a scheduler callback:
UnimplementedError
When the exception was thrown, this was the stack:
C:/b/s/w/ir/cache/builder/src/out/host_debug/dart-sdk/lib/_internal/js_dev_runtime/private/ddc_runtime/errors.dart 214:49 throw_
C:/b/s/w/ir/cache/builder/src/out/host_debug/flutter_web_sdk/lib/_engine/engine/surface/scene_builder.dart 234:5 pushShader
Is it possible to implement shimmer effect in flutter web using this plug in?
Sample Code which works on mobile but throws error on web.
import 'package:flutter/material.dart';
import 'package:shimmer/shimmer.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
visualDensity: VisualDensity.adaptivePlatformDensity,
),
home: MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
SizedBox(
width: 200.0,
height: 100.0,
child: Shimmer.fromColors(
baseColor: Colors.red,
highlightColor: Colors.yellow,

);
}
}
