Save the file and run flutter pub get to install the package.

Step 2: Import the package:

Import the buttons_tabbar package in your Dart file:

Copy Code


import 'package:flutter/material.dart';
import 'package:buttons_tabbar/buttons_tabbar.dart';

Step 3: Create a ButtonsTabBar widget:

Create a ButtonsTabBar widget and define the tabs using Tab widgets. Each Tab widget represents a tab in the tab bar:

Copy Code


Scaffold(
  appBar: AppBar(
    title: Text('Buttons TabBar Example'),
  ),
  body: DefaultTabController(
    length: 3,
    child: Column(
      children: <Widget>[
        ButtonsTabBar(
          backgroundColor: Colors.blue,
          unselectedBackgroundColor: Colors.grey[300],
          unselectedLabelStyle: TextStyle(color: Colors.black),
          labelStyle: TextStyle(color: Colors.white),
          tabs: [
            Tab(text: 'Tab 1'),
            Tab(text: 'Tab 2'),
            Tab(text: 'Tab 3'),
          ],
        ),
        Expanded(
          child: TabBarView(
            children: [
              // Tab 1 content
              Center(child: Text('Tab 1 content')),
              // Tab 2 content
              Center(child: Text('Tab 2 content')),
              // Tab 3 content
              Center(child: Text('Tab 3 content')),
            ],
          ),
        ),
      ],
    ),
  ),
);

n this example, the ButtonsTabBar widget is created with three tabs. The backgroundColor, unselectedBackgroundColor, unselectedLabelStyle, and labelStyle properties are used to customize the appearance of the tab bar.

Step 4: Run the app:

Run your Flutter app to see the buttons_tabbar in action. You should see a tab bar with three tabs at the top of the screen.
