hello sir please upload the video of when user use one button and do the two conditions are work, for example i enter amount , gst percentage select dropdownlist gst exclusive, and press calculate button on the other hand select gst inclusive in dropdown and press calculate button so tell me
Thanks @Smartherd, even though i get to see this video years after it has been uploaded yet i must confess its top notch. God bless you. pls i have been strugling with section 3.7 for about 2days now and i seem not to find a solution to the bug. onChanged: (String newValueSelected) { // Your code to execute, when a menu item is selected from dropdown _onDropDownItemSelected(newValueSelected); }, The error i'm getting is The argument type 'void Function(String)' can't be assigned to the parameter type 'void Function(String?)?'.

Code snippet: @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( backgroundColor: Colors.indigo, title: Text("Simple Interest Calculator"), ), body: GestureDetector( behavior: HitTestBehavior.opaque, onTap: () => FocusScope.of(context).requestFocus(FocusNode()), child: Container( margin: EdgeInsets.all(_minimumPadding * 2.0), child: ListView( children: [ getImageAsset(), ...... ......
