Incorrect IntrinsicHeight calculation for RichText #48679
Description
Internal: b/147481532
This IntrinsicHeight calculation being incorrect seems to be the underlying issue for a number of things that customer:money is seeing.
I've stripped it back to a simplistic example.
With IntrinsicHeight absent, this is what I see:
With IntrinsicHeight present, this is what I see:
The expectation is that both of these should look the same.
Full repro code:
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'IntrinsicHeight',
theme: ThemeData(primarySwatch: Colors.blue),
darkTheme: ThemeData(primarySwatch: Colors.blue),
home: Scaffold(
appBar: AppBar(title: Text('IntrinsicHeight Test')),
body: Align(
alignment: Alignment.topLeft,
child: Container(
color: Colors.green,
child: IntrinsicHeight(
child: RichText(
text: TextSpan(
text: 'Root\n',
children: [
TextSpan(text: 'Start\n'),
WidgetSpan(
child: Row(
children: [
Icon(Icons.edit, size: 16),
],
),
),
TextSpan(text: 'End'),
],
),
),
),
),
),
),
);
}
}
