flutter pub add atomic_ui_kit

Usage

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 reports 0.25, 0.5, 0.75, or 1.0. TimeRangeSwitch reports TimeRangeSwitchValue.day, .week, .month, or .year:

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

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

atomic_ui_kit is pure Flutter with no native code and no platform plugins. It runs on Android, iOS, web, macOS, Windows, and Linux.
