SelectionArea crashes with debugNeedsLayout is not true #125065
Description
Is there an existing issue for this?
- I have searched the existing issues
- I have read the guide to filing a bug
Steps to reproduce
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
return MaterialApp(
theme: ThemeData.light().copyWith(
useMaterial3: true,
),
debugShowCheckedModeBanner: false,
home: const Scaffold(
body: Center(
child: MyWidget(),
),
),
);
}
}
class MyWidget extends StatelessWidget {
const MyWidget({super.key});
@override
Widget build(BuildContext context) {
return const SelectionArea(
child: Column(
children: <Widget>[
Text('How are you?'),
Text('Good, and you?'),
Text('Fine, thank you.'),
],
),
);
}
}app crashes upon flutter run
This is a regression caused by #124624
Actual results
app crashed
