ListTile Hero animation throws No Material widget found #89550
Description
Here is a piece of code to reproduce the problem
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
theme: ThemeData(
primaryColor: Colors.orange,
),
home: MyHome(),
);
}
}
class MyHome extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: PreferredSize(
preferredSize: Size.zero,
child: Container(),
),
body: MaterialButton(
onPressed: () {
Navigator.of(context).push(
MaterialPageRoute(
builder: (context) => NextScreen(),
),
);
},
child: MyTile(),
),
);
}
}
class NextScreen extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(),
body: MyTile(),
);
}
}
class MyTile extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Hero(
tag: 'hero',
child: ListTile(
key: Key('hero'),
leading: Icon(Icons.ac_unit),
),
);
}
}Actual results:
when wrapping Listtile Widget with a Hero Widget, after the navigation, for a second a red widget with an error appears instead of animation.
here is the error message
The following assertion was thrown building ListTile-[<'hero'>](dirty):
No Material widget found.
ListTile widgets require a Material widget ancestor.
In material design, most widgets are conceptually "printed" on a sheet of material. In Flutter's material library, that material is represented by the Material widget. It is the Material widget that renders ink splashes, for instance. Because of this, many material library widgets require that there be a Material widget in the tree above them.
To introduce a Material widget, you can either directly include one, or use a widget that contains Material itself, such as a Card, Dialog, Drawer, or Scaffold.
The specific widget that could not find a Material ancestor was: ListTile-[<'hero'>]

══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY
╞═══════════════════════════════════════════════════════════
The following assertion was thrown building ListTile-[<'hero'>](dirty):
No Material widget found.
ListTile widgets require a Material widget ancestor.
In material design, most widgets are conceptually "printed" on a sheet of material. In
Flutter's
material library, that material is represented by the Material widget. It is the Material
widget
that renders ink splashes, for instance. Because of this, many material library widgets
require that
there be a Material widget in the tree above them.
To introduce a Material widget, you can either directly include one, or use a widget that
contains
Material itself, such as a Card, Dialog, Drawer, or Scaffold.
The specific widget that could not find a Material ancestor was:
ListTile-[<'hero'>]
The ancestors of this widget were:
...
Opacity
RepaintBoundary
IgnorePointer
Positioned
AnimatedBuilder
...
The relevant error-causing widget was:
ListTile-[<'hero'>] file:///C:/Users/adnan/bug/lib/main.dart:56:14
When the exception was thrown, this was the stack:
