Hi @haibowen
Looks like you are using a too old version of Flutter.
Can you please upgrade to the latest stable and try again
flutter channel stable
flutter upgrade --force
flutter doctor -v

If the issue persists, please provide your flutter doctor -v.

Hi @pedromassangocode

this is my code

 `import 'package:flutter/material.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 {
int _counter = 0;

ScrollController scrollController = new ScrollController();

void _incrementCounter() {
setState(() {
_counter++;
});
}

@OverRide
void initState() {
// TODO: implement initState
super.initState();
scrollController.addListener(() {
var index = scrollController.offset;
print("这个数是输出的$index");
});
}

@OverRide
Widget build(BuildContext context) {

return Scaffold(
  appBar: AppBar(
    title: Text(widget.title),
  ),
  body: ListView.builder(
    itemBuilder: (BuildContext context, int index) {
      return ItemWidget();
    },
    itemCount: 30,
  ),

  floatingActionButton: FloatingActionButton(
    onPressed: _incrementCounter,
    tooltip: 'Increment',
    child: Icon(Icons.add),
  ), // This trailing comma makes auto-formatting nicer for build methods.
);

}

Widget ItemWidget() {
return Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(5),
//color: Colors.pinkAccent,
),
height: 90,
width: MediaQuery.of(context).size.width,
child: Stack(
children: [
Positioned(

child: Text(
'标题',
style: TextStyle(color: Colors.pinkAccent),
),
),

Hi @haibowen
This error is expected because you are using the same scroll controller for multiple ListViews and this is not accepted. Make sure each Item has its own controller.
