FloatingActionBar class

A bottom-floating action bar with one large pill surface and trailing circular actions.

The bar renders:

  1. A primary pill surface that hosts child
  2. Zero or more trailing action surfaces from actions
  3. Slide and fade visibility transitions controlled by visible

Example:

FloatingActionBar(
  visible: isVisible,
  actions: [
    FloatingActionBarMenuButton<String>(
      icon: Icons.more_vert_outlined,
      items: const [
        PopupMenuItem(
          value: 'refresh',
          child: ListTile(
            leading: Icon(Icons.refresh_outlined),
            title: Text('Refresh'),
          ),
        ),
      ],
      onSelected: onMenuSelected,
    ),
  ],
  child: ChipTabSwitcher(
    tabs: const ['114-2', '114-1', '113-2'],
    padding: const EdgeInsets.symmetric(horizontal: 12),
  ),
)
