Accessibility
Please follow accessibility criteria for development.
Android’s bottom app bar component APIs provide support for the navigation icon, action items, overflow menu and more for informing the user as to what each action performs. While optional, their use is strongly encouraged.
Content descriptions
When using icons for navigation icons, action items and other elements of bottom app bars, you should set a content description on them so that screen readers like TalkBack are able to announce their purpose or action, if any.
