SidebarX is a Flutter package that provides a multiplatform navigation sidebar or side navigation bar or drawer widget. It can be used for mobile, desktop, and web applications. It is designed with maximum adaptation to large screens and is easy to use. To add SidebarX to your screen, you need to add it as a dependency in your `pubspec.yaml` file and import the package in your Dart file. You can then create a Scaffold widget and add SidebarX as a child of Row widget for large screens or as a drawer widget for small screens using the ready-made Sidebar widget. The package is under development and is open for contributions and issues.
