Problem with value update

[vincperrone]

Hi, @Ali-Azmoud I have the same problem of #1 with version 0.1.2. this is my code:

Future<void> _setCustomHours() async {
    return showDialog<void>(
      context: context,
      barrierDismissible: false,
      builder: (BuildContext context) {
        return AlertDialog(
          title: Text('Set hours', textAlign: TextAlign.center,),
          content: SingleChildScrollView(
            child: ListBody(
              mainAxis: Axis.vertical,
              children: <Widget>[
                Padding(
                  padding: EdgeInsets.only(
                    top:15.0
                  ),
                ),
                Center(
                  child: SpinnerInput(
                    minValue: 1,
                    maxValue: 10,
                    step: 0.5,
                    fractionDigits: 1,
                    disabledLongPress: true,
                    disabledPopup: true,
                    plusButton: SpinnerButtonStyle(
                      elevation: 3, 
                      height: 40,
                      width: 40,
                      color: Colors.grey[300], 
                      textColor: Colors.black, 
                      borderRadius: BorderRadius.circular(3)
                    ),
                    minusButton: SpinnerButtonStyle(
                      elevation: 3, 
                      height: 40,
                      width: 40,
                      color: Colors.grey[300], 
                      textColor: Colors.black, 
                      borderRadius: BorderRadius.circular(3)
                    ),
                    middleNumberWidth: 80,
                    middleNumberStyle: TextStyle(
                      fontSize: 14,
                      fontWeight: FontWeight.bold
                    ),
                    spinnerValue: hours, //hours is a double initialized to 1.0 in the State
                    onChange: (newValue) {
                      setState(() => hours = newValue);
                    },
                  ),
                ),
              ],
            ),
          ),
          actions: <Widget>[
            FlatButton(
              child: Text('OK'),
              onPressed: () {
                Navigator.of(context).pop();
              },
            )
          ],
        );
      },
    );
  }

When the app starts, I see the value 1.0. If I tap + or - the value in the state gets updated, while the value I see on the view is still 1.0...

Any idea? Thanks

Hi, sorry for my late response. If I understand you correctly, you want to update hours which is inside your main widget context. if this is the case, one way is using Bloc or ScopedModels, so that when you update hours in showDialog, all related widgets which are displaying hours, update themselves. I'm not sure if this is related to this package.
