It's a waiting animation when you delete a task. This is for waiting. Here you can swipe and delete a task and then you see the animation.

How we get all the data

We get all the data using getData() method from the server. 

  Future<void> getData() async {
    _isLoading = true;
    Response response = await service.getData(AppConstants.GET_TASKS);
    if(response.statusCode==200){
      _myData=response.body['data'];
      print("we got the data");

    }else{
      print("we did not get any data");
    }
    _isLoading = false;
    update()
  }

_myData is accessed on the UI using myData. 

 List<dynamic> _myData=[];
  List<dynamic> get myData=>_myData;

Once you load the data using _loadData(), you can access myData and it's properties like

controller.myData[index]["task_name"],

Loading all data after adding or editing

Make sure in your add_task.dart file you have the below code 

class AllTasks extends StatelessWidget {
  const AllTasks({Key? key}) : super(key: key);
  _loadData(BuildContext context) async {
    Get.find<DataController>().getData();
  }
...........................................................................
...........................................................................

And in the add_task.dart

GestureDetector(
                  onTap: (){
                    if(_dataValidation()){
                      Get.find<DataController>().postData(
                          nameController.text.trim(),
                          detailController.text.trim());
                      Get.offNamed(RoutesClass.getAllTasksRoute());
                    }
                  },
                  child: ButtonWidget(backgroundcolor: AppColors.mainColor,
                      text: "Add", textColor: Colors.white),
                )

and inside edit_task.dart

 GestureDetector(
                    onTap: (){
                      if(_dataValidation()){
                        Get.find<DataController>().updateData(
                            nameController.text.trim(),
                            detailController.text.trim(),
                            int.parse(controller.singleData["id"])
                        );
                        Get.offNamed(RoutesClass.getAllTasksRoute());
                      }
                    },
                    child: ButtonWidget(backgroundcolor: AppColors.mainColor,
                        text: "Save", textColor: Colors.white),
                  )

In the above method we are calling Get.offNamed(RoutesClass.getAllTasksRoute());
