After incrementing integer value on modal bottom sheet in flutter,it is updating only after closing and again opening ModalBottom sheet. as I am trying to compare qty with it so that we can compare if qty is there or not.
- StatefulBuilder( builder: (BuildContext context, StateSetter setState) => new GestureDetector( onTap: () { setState(() { value++; }); }, child: new Text( "+", style: TextStyle( color: Colors .red), ), ))
I want to increment cart value which is 1 and by tapping on '+'which is an icon, I want to incremant that 1 value on every tap on bottom sheet but what i am getting is,after tapping on '+' Incrementation of value is showing only after closing of bottom sheet and then reopen it after clicking on a product.
