       dateStart: DateTime(2023, 1, 1),
       dateEnd: DateTime(2023, 1, 10),
       data: Task(name: 'Task 1'),
       label: 'Task 1',
       subData: [
         GanttSubData(
           dateStart: DateTime(2023, 1, 2),
           dateEnd: DateTime(2023, 1, 5),
           data: 'Sub Task 1',
           label: 'Sub Task 1',
         ),
       ],
     ),
   ];
   
   @override
   Widget build(BuildContext context) {
     return Scaffold(
       body: SafeArea(
         child: GanttChart<Task, String>(
           data: ganttData,
           onDragEnd: (data, index, details) {
             ganttData[index] = data;
           },
         ),
       ),
     );
   }

4. Customize the Gantt chart as needed using the available properties and builders.
