NeuButton and NeuTheme

Register NeuTheme on the ambient ThemeData to restyle every neu widget in the subtree. Then use NeuButton:

MaterialApp(
  theme: ThemeData(
    extensions: const [
      NeuTheme(
        keyBackgroundColor: Color(0xFF252F45),
        borderRadius: 12,
      ),
    ],
  ),
  home: Center(
    child: NeuButton(
      height: 56,
      width: 200,
      onTap: () {},
      child: const Text('Buy'),
    ),
  ),
);

PercentSwitch

PercentSwitch(
  onChanged: (percent) {
    // `percent` is 0.25, 0.5, 0.75 or 1.0.
  },
);

TimeRangeSwitch

TimeRangeSwitch(
  onChanged: (range) {
    // `range` is one of TimeRangeSwitchValue.day, .week, .month or .year.
  },
);

DropdownMenuIcon

DropdownMenuIcon<String>(
  currentIndex: 0,
  items: const [
    DropdownItem<String>(value: 'one', child: Text('One')),
    DropdownItem<String>(value: 'two', child: Text('Two')),
