TabBar ignores Theme's iconTheme.size #155518
Description
Steps to reproduce
Open dartpad.dev with the latest version of Dart & Flutter. For me, that was:
- Dart 3.5.3
- Flutter 3.24.3
Paste my code sample from below.
Expected results
The icon gets its size from the theme in the TabBar and in the TabBarView.
Actual results
- For
TabBarView, the icon gets its size from the theme, as expected. - For
TabBar, the icon ignores the theme. (Bad.)
Code sample
Code sample
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
return MaterialApp(
theme: ThemeData(
iconTheme: IconThemeData(size: 64),
),
home: const Scaffold(
body: DefaultTabController(
length: 2,
child: Column(
children: [
TabBar(
tabs: [
// The icon theme is ignored for both:
Icon(Icons.backpack_outlined),
Tab(icon: Icon(Icons.map_outlined)),
],
),
Expanded(
child: TabBarView(
children: [
// The icon theme is respected for both:
Icon(Icons.backpack_outlined),
Icon(Icons.map_outlined),
],
),
),
],
),
),
),
);
}
