In this post, we both will be discussing how to change Flutter appbar height with step by step explanation and a proper Flutter example. I am sure all your doubts will be cleared regarding Flutter appbar height customization after you finish reading this post. So let’s not wait anymore and jump right into understanding how to change Flutter appbar height.
What is Flutter Appbar Height?
Flutter appbar height as the name suggests, it is the vertical size of the Flutter appbar. We will see what the default Flutter appbar height is and how to change it depending on the requirements of your Flutter app. So let’s get right into implementing it using a proper Flutter example.
Default Flutter Appbar Height
In order to visualize the default Flutter appbar height, you just have to implement a simple Flutter appbar widget. See the below code:
appBar: AppBar()

Change Flutter Appbar Height
Now to change the height of Flutter appbar widget, you have to use the toolbar height constructor of the Flutter appbar widget class. This constructor takes a double(decimal) value but you can pass integer as well, it will convert that integer to double automatically. For demonstration, I have passed a value of 100 to see what changes it will make to the Flutter appbar height. See the below code:
appBar: AppBar( toolbarHeight: 100, )

Customized Flutter Appbar Height Source Code
import 'package:flutter/material.dart'; void main() { runApp(const MyApp()); } class MyApp extends StatelessWidget { const MyApp({Key? key}) : super(key: key); @override Widget build(BuildContext context) { return MaterialApp( debugShowCheckedModeBanner: false, home: Homepage(), ); } } class Homepage extends StatefulWidget { @override State<Homepage> createState() => _HomepageState(); } class _HomepageState extends State<Homepage> { @override Widget build(BuildContext context) { return SafeArea( child: Scaffold( appBar: AppBar( toolbarHeight: 100, centerTitle: true, title: Text( 'Customized Flutter Appbar Height', style: TextStyle(color: Colors.white, fontWeight: FontWeight.w700), ), ))); } }
Conclusion
In summary, you have now learned practically with proper code implementation of what Flutter appbar height is and how to customize it in your Flutter appbar widget.
