In the world of mobile applications, navigation is key. A well-designed navigation bar greatly enhances the user experience, making it easy to access different parts of your app. Today, we’re diving into how to implement a stunning bottom navigation bar in Flutter using the Titled Bottom Navigation Bar package.

Overview of the Titled Bottom Navigation Bar

This package offers a clean and elegant bottom navigation bar with smooth animations, making navigation enjoyable for users. It comes fully packed with features and customization options. Let’s take a closer look at the features it offers:

• Custom icon color
• Custom indicator color
• Support for two to five items
• Reverse mode (show selected item as icon or title)
• Option to define custom item background color
• No need to call setState(…) to update the current index
• Support RTL TextDirection

Getting Started

To get your Titled Bottom Navigation Bar up and running, follow these simple steps:

Step 1: Add the Plugin

Open your project’s pubspec.yaml file, and add the following dependency:

dependencies:
  titled_navigation_bar: ^5.0.0-nullsafety.0

Step 2: Import the Package

In your Dart file, import the package using:

import 'package:titled_navigation_bar/titled_navigation_bar.dart';

Step 3: Adding the Widget

Now, it’s time to integrate the widget within your application. Here’s an analogy to help you understand the implementation:

Imagine you are organizing a party and need to set up a buffet table. Each dish represents an item in the navigation bar, and when a guest (user) clicks on a dish (icon), they get to know more about it (navigate to the desired screen). Here’s how you can set up your buffet table (navigation bar):

bottomNavigationBar: TitledBottomNavigationBar(
  currentIndex: 2, // This sets the default selected item
  onTap: (index) {
      print('Selected Index: $index'); // Notify when an item is clicked
  },
  items: [
      TitledNavigationBarItem(title: Text('Home'), icon: Icons.home),
      TitledNavigationBarItem(title: Text('Search'), icon: Icons.search),
      TitledNavigationBarItem(title: Text('Bag'), icon: Icons.card_travel),
      TitledNavigationBarItem(title: Text('Orders'), icon: Icons.shopping_cart),
      TitledNavigationBarItem(title: Text('Profile'), icon: Icons.person_outline),
  ],
)

Customization Options

This package allows several customization options:

• onTap – To handle item clicks.
• items – Define the items with the TitledNavigationBarItem class.
• curve – Set a custom animation curve.
• reverse – Toggle between showing Text or Icons.
• activeColor – Change the active Text/Icon color.
• inactiveColor – Set the inactive Text/Icon color.
• indicatorColor – Customize the indicator color.
• currentIndex – Set the current displayed item index.
• enableShadow – Toggle shadow effects on the navigation bar.

Troubleshooting Common Issues

While implementing the Titled Bottom Navigation Bar, you might encounter a few issues. Here’s how you can troubleshoot them:

• Issue with importing: Make sure that the package is correctly added to your pubspec.yaml file. Run flutter pub get to ensure the dependencies are loaded.
• Navigation not working: Check if the onTap function is correctly implemented and ensure the currentIndex points to a valid index.
• Styling issues: Ensure that the colors for active/inactive states are appropriately defined to avoid any visibility issues.
