How to solve: type 'Padding' is not a subtype of type 'IconData' in type cast
I am not understanding the error and where it is. Can you help me please?
This is the error message:
======== Exception caught by widgets library =======================================================
The following _CastError was thrown building:
type 'Padding' is not a subtype of type 'IconData' in type cast
When the exception was thrown, this was the stack:
#0 TodayTaskView.build.<anonymous closure>.<anonymous closure> (package:taskly/app/modules/home/views/today_task_view.dart:151:31)
And this is my homepage view code:

final controller = Get.put(HomeController());
@override

controller.getUser();

showModalBottomSheet(

Well, you have the following line in your code (twice), in class TodayTaskView:
) as IconData,
And SlidableAction wants an IconData, and Padding can't be cast to an IconData
IconData is not a widget, it is just a description of an icon. It holds an int, two String's and a bool.
Padding is a widget.
