How to use #

Typically ConvexAppBar can work with Scaffold by setup its bottomNavigationBar.

The ConvexAppBar has to two constructors, the ConvexAppBar() will use default style to simplify the tab creation.

Add this to your package's pubspec.yaml file, use the latest version:

dependencies:
  convex_bottom_bar: ^1.4.0

import 'package:convex_bottom_bar/convex_bottom_bar.dart';

Scaffold(
  bottomNavigationBar: ConvexAppBar(
    items: TAB_ITEMS,
    style: _style.value,
    curve: _curve.value,
    backgroundColor: _babColor,
    onTap: (int i) => setState(() {
      _selectedIndex = i;
    }),
  )
);

Custom Example #

If the default style does not match with your situation， try with ConvexAppBar.builder(), which allow you to custom nearly all the tab features.

Scaffold(
  bottomNavigationBar: ConvexAppBar.builder(
    count: items.length,
    backgroundColor: _tabBackgroundColor,
    style: TabStyle.fixed,
    builder: _CustomBuilder(items, _tabBackgroundColor),
  )
);
