Flutter TabBar height Icons - flutter

Question

import 'package:flutter/material.dart';
class TestTab extends StatelessWidget {
final List<Tab> myTabs = <Tab>[
Tab(
child: Image.asset(
'assets/icons/project/proj_001.png',
),
),
...
Tab(
icon: Image.asset(
'assets/icons/project/all.png',
height: 100,
),
),
...
Tab(
icon: Image.asset(
'assets/icons/project/proj_009.png',
),

];
#override
Widget build(BuildContext context) {
return DefaultTabController(
initialIndex: 5,
length: myTabs.length,
child: Scaffold(
appBar: PreferredSize(
preferredSize: Size.fromHeight(150.0),
child: AppBar(
bottom: TabBar(
isScrollable: true,
tabs: myTabs,
),
),
),
body: TabBarView(
children: myTabs.map((Tab tab) {
return Center(
child: Text(
'Test',
style: const TextStyle(fontSize: 36),
),
);
}).toList(),
),
),
);
}
}
I try to increase the icon height, but it doesn't work. It's as if he selects all the parameters himself. Does not allow reducing the width or increasing the height of elements.
Screen
Please tell me how you can increase the height of elements?

Answer 1

if u want set the icon size small then u can do like that
Tab(
text: "Category List",
icon: Icon(Icons.home,size: 15,),
),
Tab(
text: "Product List",
icon: Icon(Icons.view_list,size: 15,),
),
Tab(
text: "Contact Us",
icon: Icon(Icons.contacts,size: 15,),
),
Tab(
text: "Darshan Timing",
icon: Icon(Icons.access_time,size: 15,),
)
here size: 15, will make the icon size as you want

Answer 2

You gotta make custom TabBar for customization. Something like this.
CustomTabbar
import 'package:flutter/material.dart';
class ChangeTextSizeTabbar extends StatefulWidget {
#override
ChangeTextSizeTabbarState createState() {
return new ChangeTextSizeTabbarState();
}
}
class ChangeTextSizeTabbarState extends State<ChangeTextSizeTabbar> {
#override
Widget build(BuildContext context) {
return DefaultTabController(
length: 3,
child: Scaffold(
appBar: AppBar(
title: Text("Change Text Size Tabbar Example"),
bottom: TabBar(
tabs: <Tab>[
Tab(
child: Image.asset(
'assets/icons/project/proj_001.png',
height : 100,
width : 100,
),
),
Tab(
icon: Image.asset(
'assets/icons/project/all.png',
height : 100,
width : 100,
),
),
Tab(
icon: Image.asset(
'assets/icons/project/proj_009.png',
height : 100,
width : 100,
),
),
] ),
),
body: TabBarView(
children: <Widget>[
Container(),
Container(),
Container(),
],
),
),
);
}
}
main.dart
import 'package:flutter/material.dart';
import 'change_text_size_tabbar_task-3.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
// This widget is the root of your application.
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
debugShowCheckedModeBanner: false,
theme: ThemeData(
// This is the theme of your application.
//
// Try running your application with "flutter run". You'll see the
// application has a blue toolbar. Then, without quitting the app, try
// changing the primarySwatch below to Colors.green and then invoke
// "hot reload" (press "r" in the console where you ran "flutter run",
// or simply save your changes to "hot reload" in a Flutter IDE).
// Notice that the counter didn't reset back to zero; the application
// is not restarted.
