SliverChildBuilderDelegate null childCount can cause hanging hot reload, white screen #102904
Description
I was creating a new project to study more about slivers and custom scroll experiences, and them when I ran my project, nothing but a white screen showed up. So I tried changing colors of stuff, since there was no errors on console. But then my app froze on Hot Reload.
Then I looked through my code and remembered that I've faced the same issue months ago. When I passed 0 as a value to childCount and rebuilt my app, everything worked fine.
Steps to Reproduce
- Execute
flutter runon the code sample
Expected results:
SliverAppBar appearing.
Actual results:
White screen and the app get stuck once I try to hot reload.
Code sample
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
return const MaterialApp(
home: Home(),
);
}
}
class Home extends StatelessWidget {
const Home({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text("Normal AppBar"),
backgroundColor: Colors.green,
),
body: CustomScrollView(
slivers: [
const SliverAppBar(
title: Text(
"SliverAppBar",
),
backgroundColor: Colors.red,
pinned: true,
),
SliverList(delegate: SliverChildBuilderDelegate(((context, index) => Container())))
],
));
}
}
