ListView.builder(
   itemCount: 3,
   itemBuilder: (context, index) {
      return StickyHeaderBuilder(
         builder: (context, stuckAmount) {
            stuckAmount = 1.0 - stuckAmount.clamp(0.0, 1.0);
            if(stuckAmount == 1) print('$index is actived');
         return SizedBox();
     },
    content: Text('$index'),);
});
