What I am trying to achieve is to update change from another widget after looking after these posts Trigger a function from a widget to a State object, How to set state from another widget?, How to force Flutter to rebuild / redraw all widgets?.I tried all these solutions but because of my tree its did not worked and after many reflections I am thinking of ValueListenableBuilder using to pass the State from child to child, child to parent, and parent to the child I want to update because InheritedWidget seems to don't fit my need more over the widget will be constantly change and I think my tree make things difficult to use Stream to achieve what I want.I don't know if it's the best way to do that passing the State from child to child, child to parent, and parent to the child I want to update .this is my tree and what I am trying to achieve
The ScrollableExhibitionSheet class is a StatefulWidget; this is the code of the Raisedbutton inside the cardcontent:
Transform.translate(
offset: Offset(48 * widget.offset, 0),
child: RaisedButton(
color: Colors.green, //Color(0xFF162A49),
child: Transform.translate(
offset: Offset(24 * widget.offset, 0),
child: Text('Reserve'),
),
textColor: Colors.white,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(32),
),
onPressed: ()async {
SharedPreferences preferences = await SharedPreferences.getInstance();
String stringValue = preferences.getString('token');
print("Token $stringValue");
Dio dio = Dio(
BaseOptions(
baseUrl:base,
method: "POST",
headers: {
'Content-Type': 'application/json',
'Accept': 'application/json',
'Authorization': 'Token $stringValue',
},
));
response4 = await dio.post(
"/orders/",
data: {
"product":widget.id,
"paiment_status": false,
"timing_paiement": false,
"reserve_status": true,
"description": "",
"price":widget.price,
"number":_counter,
"relaypoint":1
});
setState(() {
print(response4.statusCode);
//ScrollableExhibitionSheet();
});
if(_counter !=0){
if(response4.statusCode == 200 || response4.statusCode == 201){
Flushbar(
flushbarPosition: FlushbarPosition.TOP,
title: "XXXXXXXXXX",
message:"${widget.name} X${_counter}",
duration: Duration(seconds: 3)
)
..show(context);
}
setState(()async{
_counter =0;
print(response4.statusCode);
getDataFromUi();
//prices(_counter,widget.price);
//sum = sum + (_counter *widget.price);
});
}else{
Flushbar(
flushbarPosition: FlushbarPosition.TOP,
title: "XXXXXXXXX",
message:"xxxxxxxxxxxxxxxx",
duration: Duration(seconds: 3)
)
..show(context);
}
//ApiData.add_orders(context,widget.id,widget.price,widget.name,_counter);
},
),
),
and this is the code of the cardcontent class:
class CardContent extends StatefulWidget {
final int id;
final String name;
final String date;
final int price;
final double offset;
Function callback;
CardContent(

this.callback,
@required this.id,

class _CardContentState extends State<CardContent> {
num _counter = 0;

Response response4;
//Count2Bloc count1Bloc;
final number = new ValueNotifier(0);
getDataFromUi() async {
await ApiData.getDataorders();
}
@override

//bool loading = false;
void minus() {
