MarkdownBody displays whitespace in lists, even though it should be ignored #134847
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
Markdown normally ignores whitespace, except for having two spaces at the end of a line of text to indicate a line break. This widget behaves well in most cases, ignoring whitespace at the beginning of paragraphs, unless there's 4 or more spaces to indicate a blockquote.
I confirmed this using several different Markdown editors.
To reproduce:
- Put multiple spaces between the list character (* or 1. or what have you) and the text value.
- You'll see that the whitespace is displayed as part of the text element. I gave the text a teal background to make it more obvious.
Clearly MardownBody is trimming text in other places, so it's probably just an oversight on this particular element type.
Expected results
A screenshot I took from the Dart Markdown Live Editor:
Actual results
Android looks the same, so I didn't bother with a screenshot.
Code sample
Code sample
import 'package:flutter/material.dart';
import 'package:flutter_markdown/flutter_markdown.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Rich Text Demo',
home: Scaffold(
appBar: AppBar(
title: const Text('Markdown Test'),
),
body: MarkdownBody(
data: '1. one space\n2. two spaces\n3. three spaces\n\n- one space\n- two spaces\n- three spaces',
styleSheet: MarkdownStyleSheet(
p: const TextStyle(
backgroundColor: Colors.tealAccent,
),
),
),
),
);
}
