No Scrollable widget ancestor could be found

Question

I'm trying implementing of slidable list item by using Slidable widget.

I get error that Scrollable.of() was called with a context that does not contain a Scrollable widget.

I expect to get something like this:

my code looks like:

import 'package:flutter/material.dart';
import 'package:flutter_slidable/flutter_slidable.dart';

void main(List<String> args) {
  runApp(
    const MaterialApp(
      home: MyWidget(),
    ),
  );
}

class MyWidget extends StatefulWidget {
  const MyWidget({super.key});

  @override
  State<MyWidget> createState() => _MyWidgetState();
}

class _MyWidgetState extends State<MyWidget> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: Slidable(
          startActionPane: ActionPane(
            motion: const StretchMotion(),
            children: [
              SlidableAction(onPressed: ((context) {}), icon: Icons.waves),
            ],
          ),
          child: Container(
            color: Colors.grey,
            child: const ListTile(
              leading: Icon(Icons.newspaper),
              title: Text("New List Tile"),
            ),
          ),
        ),
      ),
    );
  }
}

You can set closeOnScroll: false if the parent widget doesn't contains any scrollable widget.

Slidable(
  closeOnScroll: false, //this
  startActionPane: ActionPane(

Or you can use any scrollable widget on body:

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: ListView(
        children: [
          Center(
            child: Slidable(

or

return Scaffold(
  body: SingleChildScrollView(
    child: Center(
      child: Slidable(

Just needed to be on top of Slidable. Doesn't have to be on body specifically.
