Tab class

Navigation tab.

The difference with Nav, is that Tab is simpler and only supports horizontal axis for the item and widgets may also be used as tabs, meanwhile only text can be used in Nav bar.

Tab(
  items: [
    TabItem(
      builder: (context) => Center(child: Text('page1')),
      title: Text('page1'),
    ),
    TabItem(
      builder: (context) => Center(child: Text('page2')),
      title: Text('page2'),
    ),
    TabItem(
      builder: (context) => Center(child: Text('page3')),
      title: Text('page3'),
    ),
  ],
)```
