Sidebar Items

define a list of SidebarItem objects:

final List<SidebarItem> items = [  
  SidebarItem(icon: Icons.home, text: 'Home'),  
  SidebarItem(icon: Icons.notifications, text: 'Notifications'),  
  SidebarItem(icon: Icons.person, text: 'Management'),  
];

Child Items

it is also possible to define multiple SidebarChildItem for every SidebarItem.

import 'package:animated_sidebar/animated_sidebar.dart';  
  
final List<SidebarItem> items = [  
  SidebarItem(icon: Icons.home, text: 'Home'),  
  SidebarItem(  
    icon: Icons.person,  
    text: 'Management',  
    children: [  
	  SidebarChildItem(icon: Icons.person, text: 'Users'),  
	  SidebarChildItem(icon: Icons.verified_user, text: 'Roles'),  
    ],  
  ),
];

The Item Containing the Children is Collapsed and expand only on tap. If the Current selected item is a SidebarChildItem the overlying Item keeps expanded

Default usage of `AnimatedSidebar`

import 'package:animated_sidebar/animated_sidebar.dart';

@override
Widget build(BuildContext context) {
  return Scaffold(
    backgroundColor: Theme.of(context).scaffoldBackgroundColor,
    body: Row(
      children: [
        AnimatedSidebar(
          expanded: MediaQuery.of(context).size.width > 600,
          items: items,
          selectedIndex: 0,
          onItemSelected: (index) => print(index),
          headerIcon: Icons.ac_unit_sharp,
          headerIconColor: Colors.amberAccent,
          headerText: 'Example',
        ),
        Center(
          child: Text(
            'Page: $activeTab',
            style: Theme.of(context).textTheme.headline3,
          ),
        ),
      ],
    ),
  );

Use the `AnimatedSidebar` widget and handle state external :

import 'package:animated_sidebar/animated_sidebar.dart';

int activeTab = 0;

@override
Widget build(BuildContext context) {
  return Scaffold(
    backgroundColor: Theme.of(context).scaffoldBackgroundColor,
    body: Row(
      children: [
        AnimatedSidebar(
          expanded: MediaQuery.of(context).size.width > 600,
          items: items,
          selectedIndex: activeTab,
          autoSelectedIndex: false, // must be false if you want to handle state external
          onItemSelected: (index) =>
              setState(() => activeTab = index),
          headerIcon: Icons.ac_unit_sharp,
          headerIconColor: Colors.amberAccent,
          headerText: 'Example',
        ),
        Center(
          child: Text(
            'Page: $activeTab',
            style: Theme.of(context).textTheme.headline3,
          ),
        ),
