Adaptive Container

Conditionally layout per screen size

example

 AdaptiveContainer(
   configs: {
     BreakPoint.xs: AdaptiveSlot(builder: (context) {
       return Container(
         width: 100,
         height: 100,
         color: Colors.red,
         child: const Center(
             child: Text(
                 style: TextStyle(
                     fontSize: 30,
                     color: Colors.white,
                     fontWeight: FontWeight.bold),
                 'XS'),
         ),
       );
     }),
      BreakPoint.md: AdaptiveSlot(builder: (context) {
       return Container(
         width: 100,
         height: 100,
         color: Colors.green,

Breakpoints

Conditionally set values per screen size

example

Container c = Container(
    padding: valueFor<EdgeInsetGeometry>(
    context,
    xs:EdgeInsets.only(left: 25, right: 20),
    md:EdgeInsets.only(left: 25, right: 20),
    lg:EdgeInsets.only(left: 25, right: 20),
    )
);

double num = valueFor<double>(
  context, 
  xs:1,
  sm:2,
  md:3,
  lg:4,
  xl:4,
);
