CupertinoListTile overflow error #108910
Description
Note: I had already commented on the original PR about this issue, see #78732 (comment).
Steps to Reproduce
- Use the code sample on a device with a small enough screen so that the text content takes up more space than available on one line.
Expected results:
Text content should have wrapped across multiple lines.
Actual results:
Text content overflows.
Code sample
import 'package:cupertinolisttileerrordemo/cupertino_list_tile.dart';
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 MaterialApp(
home: Scaffold(
body: Center(
child: Column(
children: [
const Text('Expected behavior (like ListTile):'),
ListTile(
title: Text('Veeeeeeeeeeeeeeeeeeeeeeeeeeeeeery long text' * 5),
onTap: () {
// TODO
},
),
const Text('Actual behavior:'),
CupertinoListTile.notched(
title: Text('Veeeeeeeeeeeeeeeeeeeeeeeeeeeeeery long text' * 5),
onTap: () {
// TODO
},
),
],
),
),
),
);
}
}Logs
══╡ EXCEPTION CAUGHT BY RENDERING LIBRARY ╞═════════════════════════════════════════════════════════
The following assertion was thrown during layout:
A RenderFlex overflowed by 1276 pixels on the right.
The relevant error-causing widget was:
Row
Row:file:///C:/Users/Alex%20Sandri/Desktop/cupertinolisttileerrordemo/lib/cupertino_list_tile.dart:351:16
The overflowing RenderFlex has an orientation of Axis.horizontal.
The edge of the RenderFlex that is overflowing has been marked in the rendering with a yellow and
black striped pattern. This is usually caused by the contents being too big for the RenderFlex.
Consider applying a flex factor (e.g. using an Expanded widget) to force the children of the
RenderFlex to fit within the available space instead of being sized to their natural size.
This is considered an error condition because it indicates that there is content that cannot be
seen. If the content is legitimately bigger than the available space, consider clipping it with a
ClipRect widget before putting it in the flex, or using a scrollable container rather than a Flex,
like a ListView.
The specific RenderFlex in question is: RenderFlex#28534 relayoutBoundary=up7 OVERFLOWING:
