Description
Describe the bug:
I use Html widget nested in IntrinsicHeight and SingleChildScrollView as follows:
import 'package:flutter/material.dart';
import 'package:flutter_html/flutter_html.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
home: Scaffold(
appBar: AppBar(),
body: LayoutBuilder(
builder: (context, constraints) {
return SingleChildScrollView(
child: ConstrainedBox(
constraints: BoxConstraints(
minHeight: constraints.maxHeight,
),
child: IntrinsicHeight(
child: Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
children: [
Html(
data: 'Test',
),
const Spacer(),
Container(
height: 200,
color: Colors.red,
),
],
),
),
),
);
},
),
),
);
}
}It works well with flutter_html: 3.0.0-alpha.5 but doesn't work with flutter_html: 3.0.0-alpha.6.
Exception message is
Intrinsics are not available for PlaceholderAlignment.baseline, PlaceholderAlignment.aboveBaseline, or PlaceholderAlignment.belowBaseline.
Expected behavior:
Should render as on the screenshot from version 3.0.0-alpha.5.
