# NySwitch

<div id="introduction"></div>

## Introduction

In this section, we will learn about the `NySwitch` widget.

This widget can perform a 'switch' statement on the widgets that are passed to it.
It makes it easy to switch between different widgets based on the index.

Let's take a look at some code.

        appBar: AppBar(
            title: Text("Dashboard")
        ),
        bottomNavigationBar: BottomNavigationBar(items: [
            BottomNavigationBarItem(icon: Icon(Icons.account_circle_outlined), label: "Account"),
            BottomNavigationBarItem(icon: Icon(Icons.settings), label: "Settings"),
        ], onTap: (index) {
        setState(() {
            _currentIndex = index;
        });
        }, currentIndex: _currentIndex),
        body: SafeArea(
            child: NySwitch(widgets: [
            AccountTab(),
            SettingsTab(),
            ], indexSelected: _currentIndex),
        ),
