Introduction to Bottom Navigation

Bottom navigation is a UI element that helps add a few (generally three to five) top-level destinations in the app at the screen’s bottom. It’s a common practice to add bottom-bar navigation in an app with the most critical or frequently visited app sections, often shown with an icon and, optionally, a label, although you can customize that according to your requirements.
