Flutter/Dart: Customize Bottom Navigation Bar height

Flutter/Dart: Customize Bottom Navigation Bar height

In Flutter, you can customize the height of the Bottom Navigation Bar by wrapping it with a Container and setting the desired height. Here's an example:

import 'package:flutter/material.dart'; void main() { runApp(MyApp()); } class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( home: Scaffold( appBar: AppBar( title: Text('Custom Bottom Navigation Bar Height'), ), body: Center( child: Text('Your Content Here'), ), bottomNavigationBar: CustomBottomNavigationBar(), ), ); } } class CustomBottomNavigationBar extends StatelessWidget { @override Widget build(BuildContext context) { return Container( height: 80.0, // Set the desired height for the Bottom Navigation Bar color: Colors.blue, // Customize the background color child: BottomNavigationBar( items: [ BottomNavigationBarItem( icon: Icon(Icons.home), label: 'Home', ), BottomNavigationBarItem( icon: Icon(Icons.settings), label: 'Settings', ), ], ), ); } }

In this example, the CustomBottomNavigationBar widget wraps the BottomNavigationBar with a Container. The Container has a specified height (80.0 in this case), which you can adjust based on your preferences.

Additionally, you can customize other aspects of the Bottom Navigation Bar, such as background color and icon styling, within the Container.

Keep in mind that adjusting the height might affect the layout and appearance of the Bottom Navigation Bar, so you may need to fine-tune other properties as needed.
