Mobile applications often have various categories of content to offer. The Google Play Store app, for example, presents its content in categories such as games, apps, movies, and books. In Flutter apps, the BottomNavigationBar widget enables users to see any one category as the app starts and quickly look at the others with just the tap of a finger.

BottomNavigationBar is a widget that displays a row of small widgets at the bottom of a Flutter app. Usually, it's used to show around three to five items. Each item must have a label and an icon. BottomNavigationBar allows you to select one item at a time and quickly navigate to a given page.
