NeumorphicSwitch class

Used to toggle the on/off state of a single setting.

The switch itself does not maintain any state. Instead, when the state of the switch changes, the widget calls the onChanged callback. Most widgets that use a switch will listen for the onChanged callback and rebuild the switch with a new value to update the visual appearance of the switch.

 bool _switch1Value = false;
 bool _switch2Value = false;

 Widget _buildSwitches() {
   return Row(children: <Widget>[

     NeumorphicSwitch(
       value: _switch1Value,
       style: NeumorphicSwitchStyle(
         thumbShape: NeumorphicShape.concave,
       ),
       onChanged: (value) {
         setState(() {
           _switch1Value = value;
         });
       },
     ),

     NeumorphicSwitch(
       value: _switch2Value,
       style: NeumorphicSwitchStyle(
         thumbShape: NeumorphicShape.flat,
       ),
       onChanged: (value) {
         setState(() {
           _switch2Value = value;
         });
       },
     ),

   ]);
 }
