multi_navigator_bottom_bar

Helps you to build multi-navigator bottom navigation bar more easily.

Usage

There is an example app in the repo. Part of the main scenario:

class _MyHomePageState extends State<MyHomePage> {
  static final tabSize = 4;
  var tabs = List.generate(
    tabSize,
    (index) => BottomBarTab(
          initPage: Page(index.toString()),
          tabIconBuilder: (_) => Icon(Icons.add),
          tabTitleBuilder: (_) => Text("Tab ${index.toString()}"),
        ),
  );

  @override
  Widget build(BuildContext context) => MultiNavigatorBottomBar(
        initTabIndex: 0,
        pageWidgetDecorator: pageDecorator,
        tabs: tabs,
      );

  Widget pageDecorator(pageWidget) => Column(
        children: <Widget>[
          Expanded(child: pageWidget),
          Container(
            alignment: AlignmentDirectional.center,
            height: 48.0,
            color: Colors.black,
            child: Text(
              "PageWidgetDecorator",
              style: TextStyle(color: Colors.white),
            ),
          )
        ],
      );
}
