    Call your code that calls setState with some delay like the following example.

    Future.delayed(Duration.zero, () async     {
   setState(() {
      myController.text = widget.valueText ?? '';
   });
});

    The error is telling you that you are trying to rebuild the widget in the process of building the widget.

    To resolve this issue, simply call this line of code in the initState() method to ensure that it will be called once just before the first frame is displayed.

     @override
 void initState() {
   super.initState();
   myController.text = widget.valueText ?? '';

 }
