                reloadAfterInit: true,

            axisLabel: {              
              formatter: {

although i put reloadAfterInit=true, its still blank/not showing chart. but after i put some delay to in build method, it show now.

Future.delayed(Duration(milliseconds: 100), () {
      setState(() {
        _show = true;
      });
});

I use android 11

I use too many time setState() where did you put show?
